CERAMIC DIVERSITY IN CHAVIN DE HUANTAR, PERU
Isabelle C. Druc
Ceramic diversity in the ceremonial center of Chavin de Huantar in the Peruvian highlands is assessed by neutronactivation analysis, petrography,and stylistic analysis. Theseanalyses lead to a new interpretationof ceramicproductionin Chavin
between ca. 850 and 200 B.C. Several compositional groups with very differentmineralogical paste types are identified.
More than 30 percent of the ceramics are nonlocal. Most of these are bottles and fine wares, probably brought to the site
as gifts or offerings. At the local level, ceramic production changed over time. A dramatic shift in resource procurement
occurred at the end of the first occupation phase, and production became more diversified and intense as the site and its
population grew larger

by the presence of nonlocal commodities like

Huantaris seen as representinga synthesisof earlier traditionsanda centerfromwhich ideas,if not
objects, radiated.Indeed, Chavin-styleceramics
are common at manyPeruviansites. It was, however,not certainif theirpresencewas the resultof
imitation(diffusionof ideasor styles)or trade(diffusionof objects).This questionpromptedthe present INAA (instrumental neutron activation
analysis) study, which completes earlier provenancestudieswithpetrographyandXRF(x-rayfluorescence) analyses of Chavin ceramics (Druc
1998a).A few compositionalstudieshadbeenpreviously undertakenbut not at a regionallevel and
withprovenancein mind.Theseearlieranalysesare
first reviewed to place the present study in perspective.Methodologyandresultsfollow.
A Review of Chavin Ceramic Analyses
Although stylistic analysis offers insight into the
provenanceof ceramics,compositionalanalysisof
the pastehelps to differentiatelocal productsfrom
imports,thusprovidinga meansto investigateinterregional interactions.The initial compositional
studiesof ceramicsfrom Chavinde Huantarwere
undertakenin theearly1980s.Thefirststudy,a petrographicanalysisof nineceramicthinsectionsby
RobertTracy,was publishedin RichardBurger's
(1984) excavationreport.The samplescame from
ceramicsfound outside the ceremonialcenter,in
the surroundingChavin settlement.Tracyidentified several mineralogical compositions (with
quartz,plagioclase,biotite,homblende,metamorphic, fine-grainedvolcanic, and plutonicigneous
rockfragments).His observationscorrespondto my
analyses.
The second study, using Maissbauer spectroscopy (MS), instrumentalneutron activation
analysis (INAA), and X-ray diffraction(XRD),
was conductedby a Germanteam (Salazaret al.
1986) on 61 Chavinsherdsfrom an interiorcorridor of the old temple of Chavin,50 surfacefinds
(Chavin),two ancientsoil samples,andone modem clay sample.The aim of the studywas to classify the samplesandlearnaboutfiringprocedure.
The hierarchicalclusteringof the INAA results
produced five groups with chemically distinct
pastes.The largestgroupincluded57 Chavinand
post-Chavinceramics,andthe recentclay sample.
It was thereforeassumedthatthe wareshad been
345
locally produced.The MS analysisindicatedthat
the ceramicswere firedin a reducingatmosphere
followed by an oxidationphase.X-raydiffraction
(XRD) identifiedsome of the mineralswithinthe
ceramics: black talc and feldspar for the main
group, and amphibole crystals for some of the
other samples.
These two studies showed that ceramics at
Chavin de Huantarhad variedcompositionsand
some were of nonlocal origin. Stylistic analysis
had produceda similarconclusion(Burger1984;
Lumbreras1977, 1993). Based on style, northern
andcoastaloriginswereproposedfor thenonlocal
wares.
Anothercompositionalstudy(MS, INAA, thin
section microscopy)was conductedby the same
Germanteam(Lumbreraset al. 2003) on 70 sherds
from the OfrendasGalleryof Chavinde Huantar.
Thisgalleryis famousformorethan500 finebowls
and bottles, believed to be offerings left in the
gallery on multiple occasions (Lumbreras1977,
1993).The Ofrendasmaterialis, however,stylistically differentfromtheotherceramicsfromtheceremonialcenteror the surroundingsettlement.The
hierarchicalclusteringof the INAA results conformed to stylistic groups within the Ofrendas
material.Gebhardet al. (1996) suggesta nonlocal
provenance,butno comparativematerialfromother
siteswas analyzedto allowidentificationof origins.
Stylistic affinitiespoint to the central and north
coast, andto the northernhighlands(Burger1984;
Lumbreras1993).
Until 1994, no comprehensive study of a
regional scale had been attemptedto understand
how potterywas producedin the Chavinarea.Was
it madeatdifferentworkshops?WereChavin-style
ceramicscentrallyproducedandthendistributed?
No ceramicworkshopsorkilnshavebeen foundin
Chavinde Huantaror in the nearbyregion.
A studyof ceramicproductionanddistribution
in the Chavinsphereof influence(Figure 1) was
conducted in 1993-1997 (Druc 1998a, 1998b),
usingpetrographyandenergydispersiveX-rayfluorescenceanalysis(EDXRF).The studyincluded
soil andmodemclay
284 ceramicsand69 modemrn
samplesfromsix siteslocatedin five differenthighlandandcoastalregions(Chavinde Huantar,Huaricoto,Pallka,Anc6n,andtwo smallsitesin Nepefia).

locally made imitations.Furthermore,it proveda
small-scaleexchangeof bottlesandfinebowls into
the ceremonialcenterof Chavinde Huantar,(and
not outwardfrom Chavin).This conformsto the
idea of Chavinde Huantaras a pilgrimagecenter.
The study also yielded new insights into ceramic
production.Petrographicanalysisshowedthatthe
wareswereproducedin severalworkshopsor production areas at each site, and that bottles were
very often producedwith a fine paste.
Thepatternof productionattheceremonialcenter of Chavinde Huantar,however,provedmore
complexthanat anyothersite studied.The ceramics analyzedin the 1993-1997 study come from
the ceremonialcenter(n = 86) and the associated
settlement(n = 23). As seen in priorstudies, the
ceramicsshow high compositionalheterogeneity.
Six differentcompositionalgroupsandsubgroups
were petrographicallyidentified,along with unattributedspecimens of atypicalcomposition.Two
maingroupsareidentifiedas local. One is characterized by a volcanic-derivedpaste (pyroclastic
sandwith quartz,plagioclase,biotite,hornblende,
welded rhyolitictuff fragments),and the otherby
an intrusive-derivedpaste (quartz, plagioclase,
biotite, augite, granodioritefragments).A third
composition
groupof mixedintrusive-sedimentary
was also foundto be local, on the basis of geological and abundancecriteria.Subgroupsaregranulometricor modal variants.Ceramicswith exotic
pastesdisplaymetamorphiccomposition(quartzmuscovite-schist) or rare compositions (felsic,
granitic)not correspondingto local geology (for
detailssee Druc 1997, 1998a).The EDXRFanalysis suggestedthatat least 30 percentof the ceramics found in Chavinde Huantarwere of nonlocal
production.This figureconformsto the findingof
the INAA studyby Salazarandcolleagues(1986),
where25 percentof thewareswerefoundto be nonlocal (20 out of 76 wares).

Althoughx-rayfluorescenceworkedwell atthe
intersitelevel, it failed to distinguish individual
groupsat the intrasitelevel andwouldnotpartition
the corpus as accuratelyas petrographicclassification.Forthis reason,andto get a clearerpicture
of ceramicproductionat Chavinde Huantar,it was
decided to submit the Chavin corpus to another
roundof analysis,this time using neutronactivation. In addition,the chemicalresultscould be triangulatedwith differentsets of data:petrographic,
geological, stylistic, archaeological, and ethnographic.The resultsof this last studyarepresented
here.
The methodologywill be describedfirst.The
resultsarethendiscussedin light of the chemical,
mineral,and stylistic data.Finally,the discussion
is enlargedto reacha higherinterpretative
levelwith
regardto ceramicproductionthroughtime in relation to the developmentof Chavinde Huantarand
interregionalinteractions.
Methodology
Several questions defined the objectives of the
INAA study. Its goal was identifying and interpretingintrasitechemicalgroupsandinvestigating
compositionaldifferencesin relationto time and
space. How many differentchemical groups are
therein Chavinde Huantarceramics?Whatdo they
reflect?Is therea change in ceramiccomposition
throughtime? Is therea centralizationof production? The sample is comprisedof 81 specimens
fromChavinde Huantar(56 sherds,and25 thathad
alreadybeen used for EDXRF), and 20 pressed
powderpellets from sherdsfrom the sites of Pallka, Huaricoto,Anc6n and Garagay(Figure1) for
comparativepurposes.No bindingagentwas used
for preparingthe pellets,whichwerekeptin a desiccatorafteruse. The sampleshaveknownmineral

Most of the analyzed ceramics from Chavin de
Huantarare represented in Figure 2. They are
grouped according to the chemical and mineralogicalgroupsin Table3. Vessel formsper group
are listed in Table2.
The neutronactivationanalysiswas conducted
at the SmithsonianCenterfor MaterialResearch
and Education(SCMRE)and at the nuclearreactorfacilityof theNationalInstituteof Standardsand
Technology(NIST).Neutronactivationanalysisin
general,andthe procedurefollowed at NIST,have
been amply described elsewhere (Bishop and
Crown 1994; Bishop et al. 1982; Glascock 1992;
Perlmanand Asaro 1969). James Blackmanand

The elements were chosen accordingto smallest

Differentclusteringmethodsas well as principal componentanalysis(PCA),using bothcovariance-variance and correlation matrices, were
explored. Cluster analysis was conducted using

ceramiccompositionsfrom Chavinde Huantar.
Results and Discussion
Eightcompositionalgroupsof archaeologicalsignificancewere identifiedin the hierarchicalclassification of the 56 samples from Chavin de
Huantarand 20 comparativesamples from four
other sites. These chemical groups are presented
in Table3, along with informationon mineralogy,
form, style, chemistry,and possible source areas;
the sherdsamplesfor each groupareillustratedin
Figure2.
The PCA scatterplot for ceramicsfromChavin
de Huantarshowsfive groups(Figure3). The main
chemical variablesresponsiblefor this classification are (by orderof importance):Cs, Th, La, Ce,
Rb, andK, for PC1, andCR, LU,YB, SC for PC2.
Thefirstprincipalcomponent(PC1)explains42.34
percentof the varianceandthe second(PC2)23.25
percent.
The chemical groups show internal heterogeneity.Compositionalvariabilitywithinclusters
is above 17 to 20 percentfor most of the elements,
suggestingmultipleoriginsfor the samplesin the
sameclusteror the existenceof severalworkshops
using clay from differentlocalized sourcesin the
same productionarea. Consequently,representation in multivariatespace, such as a PCA scatter
plot, is not easily interpretedvisually.The groups
are spreadout and give the impressionof being
intermixedbecauseof the reductionin the number
of dimensionsto two orthree,particularlyso when
the samples from the comparative sites are
included.Nevertheless,the chemicalgroupspoint
to productionareas with internallysimilar geochemicalenvironment.Due to the degreeof compositionaldiversityin Chavinde Huantarceramics,
the sampleclassificationby clusteranalysison logtransformeddatais moreinformativethanthePCA
andprovidesthe basis for the discussion.
Sample Classification
Thehierarchicalclassificationreflectsthemainpetrographicgroups observed in mineral analysis:
acidic volcanic, intermediateto basic intrusive,
fine/sedimentary,and mica tempers.The clustering constructedwiththecompletelinkmethodfollows an acidic to basic trend, with the acidic
[Vol.15, No. 3, 2004]
volcanicsampleson one endof thedendrogramand
the basic intrusivesampleson the other.Elemental variationsoccuraccordingly,allowingthe characterization of the mineral trends in terms of
chemicaltendencies.Table4 gives the concentration rangesfor each compositionalgroupderived
by this method. Values outside the range are in
parentheses,while valuesforoutliersarenotgiven.
The group numbers in parenthesesrefer to the
groupsformedby averagelinkage listed in Table
3. Differencesbetween the acidic and basic poles
are mostly seen amongtraceelements.The acidic
pole is characterizedby low Sc, and high Rb, Cs,
La, Ce, and Th (the reverseis true for the basic
pole). Ironcontentshows differencesaccordingto
the mineralogyor provenancewithinthe clusters,
witha low rangein thevolcanicgroupanda higher
one in the basic-intermediate intrusive group.
Exceptions in chemical trends are observed for
ceramics from the coast (Anc6n and Garagay),
Huaricoto,a few Chavin samples, and the three
mica-temperedceramics.Samplesfrom the comparativesites arefoundin compositionalgroups3,
5, 7 and 9 and as outliers.
In the complete-linkdendrogram,some groups
encompasssampleswith differenttempercomposition, althoughsimilaritiesin mineralcontentare
observed.Chemicalvariationsthatexist in theclay
may not be observedin petrographydueto the resolutionof the microscope.The clay matrix,which
often representsmorethan50 percentof the paste
of the Chavin ceramics (Druc 1997), is largely
uncharacterized.Consequently,finer distinctions
arereachedwithINAAthanwithpetrography
when
dealingwithfineorlow-temperedfragments.Samples with similartempermay thus displaychemical variationsrelatedto the use of a differentclay
paste. This is the case for the two Garagayollas,
G4 andG6, whichwerebothtemperedwithcrushed
granodioritebuthaddifferencesin Cs, Ba, Tb, Ta,
Th, andRb content.Theirmineralogicalcomposition is verydifferentfromtherestof theAnc6nand
Garagayceramics (see Druc et al. 2001), hence
theirseparateclustering.
The dendrogrambuilt using the average-link
method does not follow the same acidic to basic
trendin the orderingof the clusters.Nevertheless,
the constitutionof the groupsis similar.The average-linkmethodyields a morehomogeneousclusteringof the samplesrelativeto theirmineralogy.

Cs as Site Discriminant
In orderto allow a closer examinationof the data
andto see whichelementscharacterizeeachgroup,
the chemical raw data were listed following the
orderof the hierarchicalclustering.One element
in particular,cesium (Cs), provedto be important
in theclassificationof thesamples.Cesiumappears
to be a site discriminator,with high Cs content
(above 11 ppm)suggestinga nonlocalprovenance
fortheChavinsherds.However,thiscriterionis not
thesole indicatorof foreignprovenanceandit must
be appliedin conjunctionwith otherinformation
like the style, mineralogy, and archaeological
provenanceof the sherds.
Cesium is likely to be found in late-stage-formationcrystalsin acidicrocks,in leucite,feldspar,
and similarminerals(BruceVelde,personalcommunication2001). Itis also foundas tracesin black
mica(biotite)(FoucaultandRaoult1995),in white
mica (muscovite) in pegmatite,but not in metamorphicrocks (BruceVelde, personalcommunication2001). Thispointis importantto understand
the relativelylow Cs contentin the ceramicstemperedwith quartz-muscoviteschist (mica temper,
Table 3). These wares are nonlocal, as no metamorphicrocksareknownin the regionof Chavin.
High cesium contentmay also point to the use of
a micaceousclay to producethe ceramics,due to
the preferentialabsorptionof Cs associatedwith
micaceousclaysovergeologicaltime(RonBishop,
personalcommunication1998).
As a corollary,ceramicsfound in Chavinwith
Cs contentbelow 11 ppm areprobablylocal. This
is observedfor all theceramicsin thebasicto intermediateintrusivegroupandthesedimentary-intrusive group,and for most ceramicsin the volcanic
group.Theirmineralogyalso correspondsto local
resourcesaroundChavinde Huantar.

The chemical tendencyshown in Table 3 and
theassociatedmineralogysuggestthatCs is a componentof acidic volcanicrocks, while it is of low
abundancein ceramicswith intermediateto basic
intrusivepaste. Its presenceis linked to the geological environmentof the sourceareafor ceramic
production.The high Cs content of the coastal
ceramicsfromAnc6n andGaragay,andHuaricoto
in the Callej6nde Huaylas,is probablyrelatedto
the volcanicsof thoseregions.On the contrary,the
Mosna-Chavinregionis characterized
by intrusivegranodioritic and sedimentary geology, which
explains the lower Cs content in local Chavin
ceramics.

Based on cesium content,mineralogy,local geology, and style, severalceramicsfound in Chavin
de Huantarwereidentifiedas nonlocal.Inthecluster analysisof the INAA results,they standout as
outliers or they group separatelyfrom the main
Chavinceramics(Groups1 and2). Mostof thestylistically atypicalceramicsare found in Groups7,
6, and 5.

These include four jars (3742c, 3748b, 3764a,
3786g) and three bowls (3708A, Mosna bowl
3755a, oversized bowl 3764b). Chakinanibowl
3708A has very high Cs (56.90 ppm) and low Na
and Fe values. Its paste is not tempered and
extremely fine, unlike any other paste found in
Chavin.An earliermicroprobeanalysisof the clay
matrixof bowl 3708A showedSi/Al ratiosof 4.20
to 4.91, well above local Chavin ceramics with
ratios from 1.98 to 2.00 in the illite-montmorillonite range(Druc 1997; Newman 1987).
ThehighCs contentof severaladditionalsherds

3745a), four circle-and-dotbowls (B21, 3775a,

The other atypical bowls and bottles (3762,
3787B, 3790, 3784f, 3787a) have normalCs content but they cluster separately from the local
ceramics. They have sedimentary or intrusive

The final clearly nonlocal group is the mica
group(Group8, Table3). Thewhite mica flakesin
the clay matrixcome from crushedquartz-muscovite schistfragmentsaddedto theclayby thepotter.Thismineralogicalcompositionis foreignto the
Mosna Valley geology. A high Cs content was

Table 5 summarizes these results. Nonlocal
ceramicsat Chavinde Huantarvaryin form,paste
composition,and date, as will be detailedbelow.
The provenancediversity for volcanic-tempered
wares bears particularsignificancewhen considering the production scenario throughout the
Chavinoccupationof thesite.Compositionaldiversity suggests multiplenonlocal origins. Nonlocal
waresreach30 percent,andupto 40 percent,if one

Local Productionat Chavinde Huantarand
Local Geology
Local geology and the abundancecriteria(Harbottle 1982; Shepard 1968) determinethe local
characterof a group.Groups1 and2 (Table3) consist of ceramicswithmineralcompositionsmatching the local geology. They are termed "local
groups"andrepresent22.2 and23.4 percentof the
Chavinsample.Partof Group4, characterizedby
a sedimentarypaste, is certainlyalso local. The
threemainpetrographic
groupsidentifiedin Chavin
ceramics(volcanic,intrusive,andsedimentary)are
compositiontypes foundwithina 20 km radiusof
the site (Figure4).
The local geology consists of Quaternaryalluvial and glacial deposits at the bottomof the valley, sedimentary rocks of Late Jurassic age
(ChicamaFormation:dark shale and dark limestone, sandstoneand tuff), and LowerCretaceous
sedimentaryrocks (Oy6n Formationand Goyallarisquisgagroup:shale, slate, coal seams, limestone quartzite,and arenite)on the valley slopes
(Cobbinget al. 1996:73-74; Turneret al. 1999).

fragmentsand in the paste of the volcanic-temperedsherds.This is peculiarbecausehornblende
is normallybrown in volcanics. Ignimbritictuffs
from the Black Cordillerahave no hornblende
(RobertStrusievicz,personalcommunication1998
and 1999), which rules out a provenancewest of
the Rio Santafor the tuff-temperedsherdsfound
in Chavin.
Othersourcesof volcanictuff are closer to the
site. The LateJurassicChicamaFormationunderlyingtheMosnaValleyis composedof volcanictuff
along with darkshale, darklimestone, and sandstone (Figure 4; Turner et al. 1999:48-49).
Althoughthis formationcould have been a source
for the Chavinpotters,its mixed sedimentaryand
tuff compositiondoes not match the paste of the
volcanicgroup.However,bouldersof volcanictuff
are reportedaroundthe site and along the river
banks(Turneret al. 1999:55),andtheymaybe part
of a rock fall or landslidefrom the uppervalley
slope to the east. Unfortunately,therehas been no
petrographicanalysisof these boulders.However,
it is likely thatthe local pottersused these soft tuff
rocks as temperingmaterial.
Theuse of volcanictuffwas notrestrictedto potteryproduction.Twodifferentkindsof porousvolcanic tuff were used for carving some of the
columnsandtenonnedheadsof Chavin(Turneret
al. 1999:55).It is likely thatthe potterswere aware
of this stonecarving"industry"andmay havebenefitedfromit by usingtuffdebris.This impliesthat
theywouldnothaveneededto go too farto get their
temperingmaterial,if stone carving was a local
activity,as suggestedby theamountof stonesculpturesin Chavin.
Theremaywell havebeenmultipleceramicproductionlocationsorworkshopswithintheresource
areasdescribedabove,which in turnmay account
for compositionalvariationsrelatedto spatialdistributions.Ignimbriticor pyroclasticdepositsrepresent a good example of such compositional
variability,as their mineralassemblagesvary by
depthof depositflow anddistancefromthe source.
This can account for the chemical heterogeneity
observedwithina single cluster.However,to confirmthe locationof the procurementareas,intensive samplingandpetrographic

CeramicProductionthroughSpace
and Timein Chavin
Elevenceramicsamplesfromtheancientsettlement
to the northand from aroundthe ceremonialcenter were included in the analysis. They are dispersed through the hierarchical classification,
togetherwiththose fromthe ceremonialarea,suggestingthatthechemicalcompositionof thesherds
is not linked to spatialdistributionwithin the site
areaas a whole.Inotherwords,no particularworkshop was producingexclusivelyfor the residential

and Chakinaniceramics(Group1, Table3). Only

probablynonlocal.
The diversityof pastes within the volcanic group
and the domesticcharacterof the wares(ollas and
jars) suggest a differentproductionscenariothan
for later periods.The chemical diversityand the
domestic characterof the volcanic wares (ollas,
bowls, a fewjars)duringtheUrabarriuphasepoint
to the existenceof multiplesmall-scaleproducers
aroundandaboveChavin,whilefinebowlsandbottles were producedin or broughtinto the valley.
Volcanicmaterialresiststhermalstresswell (Rice
1987; Shepard 1968), which suits the domestic
characterof the Urabarriuwares. These wares
reflect a demand for simpler,less-diverse forms
thanthose of laterperiods.This patternof multiple local productionlocationsalso is observedfor
other sites and is associated with compositional
diversitywithin the coarse ware inventory,while
fine bowls and bottleshave a more homogeneous
compositional profile (Chapdelaineet al. 1995;
Druc 1998a).Burgernotesthe coarseexecutionof

CeramicProductionduringthe Chakinaniand
JanabarriuPhases. The use of volcanicresources
declined,and half of the ceramicswere tempered
with sedimentarymaterialor a mixedtemper(sedimentary,volcanic, and intrusivefragmentsin the
paste)duringthe Chakinaniphase.Intrusivematerial from the White Cordillerawas mostly used
during Janabarriutimes to produce all types of
wares.Only a few ceramicshave a sedimentaryor
volcanicpaste.This suggests a switch in resource
areasandworkshoplocations,andtheexploitation
of intrusivematerialsfrom resourceareaswest of
Chavin,along the flanksof the White Cordillera.
Workshopsat the time of the maximumextentof
Chavinde Huantar(390-200 B.C.) were probably
locatedto the west, in agreementwith the distribution of modernpottingvillages along both sides
of the WhiteCordillera(Druc 1996, 2001).
No temporalvariationis observedforthemixedcomposition and fine-pasteceramics (Group4).
This was also seen in an earlierstudy based on a
largersamplethan the one used for INAA (Druc
1998a). These ceramicswere probablyproduced
in smallquantitythroughoutthe occupationof the
ceremonialcenteror were broughtfrom production centersoutsidethe MosnaValley.The present

It is interestingto note the rarityof ollas and
absence of coarse ware in the nonlocal ceramics.
Instead,the majorityof the nonlocalceramicsare
nondomesticwares,liquidor transportcontainers

and3786g, andbowl B20. Bottle3762 is decorated
with graphiteoverred,a style calledWacheqsaby
Lumbreras(1977, 1993) and supposedlyfromthe
Cupisnique region on the north coast or correspondinghighlands.However,the use of graphite
decorationis alsoknownfromtheKotosh-Huanuco
region,southeastof Chavin(Burger1984;Lumbreras 1993).
Bottle 3765a was originally attributedto the
coast by discriminantanalysisusing x-rayfluorescence data (Druc 1998a). It is now groupedwith
Pallkasherds,regardlessof the clusteringmethod,
even whensamplesfromthecoastalsites of Anc6n
andGaragayareincluded.The CasmaValleyis the
probableprovenancesite of this bottle.This placementis morein agreementwithbottlestyle at both
sites and, above all, with petrographicanalysis
(unavailablefor this sampleat the time of the XRF
analysis).PallkabottleP23 withfineintrusivepaste
clustersin Group3 withChavinoutliers,separately
from the otherPallkasherds.Its origin, however,
is not Chavinde Huantar,due to its mineralcomposition thatdoes not matchlocal Chavinmineralogy.
Along withthe sherdsfromtheceremonialcenter of Huaricotoin the Callej6nde Huaylasis the
oversizedbowl 3764b.Itis a largered-slippedbowl
materialand
temperedwithpyroclastic-ignimbritic
weldedtufffragmentsat a time (Janabarriu
phase)
when thistype of temperwas no longerused in the
region of Chavinde Huantar.The presenceof an
andesite fragmentin the paste suggests that the
materialcame froma volcanicrockof the Tertiary
Calipuy Formation.This rock type is not found
nearChavin.Themineralcompositionof thisbowl
is consistentwith sourcesof volcanictuffandignimbritecommonin theCallej6nde Huaylas(Robert
Strusievicz,personalcommunication1999; Cobbing et al. 1996). The Callej6n is easily reached
througha mountainpass just above Chavin.The
provenanceof this bowl, however,is not the small
ceremonialcenterof Huaricoto,judging from the
lack of mineralsimilaritywith the ceramicsfrom
thatsite.
SeveralotherceramicsfromChavinclusterseparately from the Chavin local groups (#3744,
3742c, 3787b, 3755a, and B21) or from samples
fromthe coast. Manyof these come fromatypical
ceramics,whose style ormineralcompositionsuggests a nonlocal provenance,as yet unidentified.
[Vol.15, No. 3, 2004]
These sherds have been discussed in relationto
theirhighCs content.TheMosnaRed-over-Orange
oripaintedsherdin Group4 is also of unattributed
gin. Its style suggestsa northernprovenance,from
the regionof Pacopampa(Lumbreras1993). Last,
the finesand-pasteChakinanibottle3755c andsedimentarypaste olla 3741d are linked to samples
fromthe coastalsites of Anc6nandGaragay.Their
mineralogy,however,is differentfrom the coastal
paste found in Anc6n and Garagay(Druc et al.
2001) and rules out a centralcoast provenance.
Conclusions
Priorchemical analyses hinted at the wide compositionaldiversityof the ceramicsin Chavin de
Huantar.FurtherpetrographicanalysisandINAA
studiesallow this diversityto be linkedto production scenarioschangingover time, and to a considerable amount of nonlocal wares. Several
observationson ceramicproductioncan be made
at the local and interregionallevels. Accordingto
chemical and mineralanalyses,severalcentersof
productionwere supplyingthe ancientsettlement
and ceremonialcenter of Chavin de Huantar.At
least threelargeproductionareascan be proposed:
two in thelocal highlandssouthandwest of Chavin
and one in the valley bottom. Severalworkshops
were probablyactivein each area,as suggestedby
the internal heterogeneity of the compositional
groups.Also, manyproductioncentersmust have
been in use at differenttime periods.The use of
material,oftenwithwelded
ignimbritic-pyroclastic
tuff fragments,is observedduringthe Urabarriu
phase, the first occupation phase at Chavin de
Huantar.The workshopsusing this materialwere
probablylocatedupto 12kmfromtheresourcearea
(estimateddistance based on ethnographicdata,
Druc 1996), south and southeastof Chavin, and
northeastof the site abovethe village of San Marcos (Figure5). Some of the workshopsalso could
havebeen locatednearthe site, using tuffboulders
scatteredalongtheMosnariverbanks,ortuffdebris
fromvolcanicstone-carvingactivity.Laterin time,
duringthe maximumextensionof the site, the tendency was to use intrusiveraw materials,and the
workshopsmusthavebeen locatedwest of the settlement,usingmaterialsfromtheslopeof theWhite
Cordillera.

The workshopslocatedhigherup in the valley

wares were ollas and bowls. As the site grew and

on pasteanalysisalone.Resourceexhaustion,landslidesthatburiedsources,ortechnologicalchanges

factors were the economic expansionof the site,
population growth, higher demand for ceramic
products, and the establishmentof new potters,

and located immediatelynorthof the ceremonial
area.Chavingrew duringthe Chakinaniphase to
an estimated 15 ha and to 42 ha duringthe Janabarriuphase,with the settlementextendingsouth
of the ceremonialcenter(Burger1984, 1992).The
ceremonialcenteralonecoveredsome 1.5ha in the
early periodsto 5 ha at its maximumextent.Severalvillages abovethe valleyfloorandin the highlands surroundedChavin.The highlandvillages
appearto have been occupied mainly duringthe
Urabarriu
phase,ata timewhenvolcanicresources
were used for ceramicproduction.Archaeological
evidence shows a dispersedpopulationduringthe
Urabarriuand Chakinaniphases,and a moreconcentratedand dense occupationduringJanabarriu
times, reflectedin the ceramicproductionpattern.
During the Urabarriuphase, the diversityof volcanicpastessuggestsdispersedceramicproviders,
probably responding to low demand. A more
diverseandintenseproductionis suggestedduring
the Janabarriuphase, when the valley was more
heavily populated.The absenceof atypicalwares
in thevolcanicandintrusivegroupsis in accordance
with the hypothesisof local highlandproduction
for utilitarianware.
The region providingthe Chavin de Huantar
populationwithutilitarianwaremusthaveextended
well beyondthe site. Untilthe early 1970s,potters
fromYacyaandMallas(Figure5), 30 km northin
the highlands above the lower Mosna Valley,
walkedto Chavinto bartertheirpots (Druc 1996;
RichardBurger,personalcommunication1998).
These conclusionssupportBurger'shypothesisof
the Chavin Temple drawing services and goods
from communitiesup to the lower Mosna Valley
and southern Callej6n de Huaylas (Burger
1984:249).In additionto the religiousimportance
of the ceremonialcenter,Chavinmusthavebeen a
centralplace for fairs and exchange of local and
interregionalproducts,including ceramics. Economic and culturalinteractionsexplain the wide
diversity of pastes and variety of origins of the
ceramicsin Chavin.
At the level of interregionalinteractions,the
importanceof Chavinde Huantaris demonstrated
by thenumberof atypicalandnonlocalwaresfrom
the Urabarriuphaseon. None of the sites analyzed
previously (Pallka, Huaricoto,Anc6n, Garagay
[Druc 1998a;Druc et al. 2001]) show this diversity of pasteandnumbersof atypicalandnonlocal
wares,attestingto the interregionalscope of interactionswith the ceremonialcenter.Most nonlocal
wares are bottles and fine bowls thatwere probably not destinedfor domesticuse in view of their
style, decoration,and rarity.One bottle may be
fromthe ceremonialcenterof Pallkain the coastal
valleyof Casma,whilea largebowlprobablycomes
from the Callej6nde Huaylas,on the otherside of
theWhiteCordillera.Abouta thirdof the nonlocal
waresarenon-Chavinin style andmay come from
cultural areas outside Chavin influence whose
inhabitantswere awareof the religious centerof
Chavinde Huantar.
This INAA study yields a clearer picture of
ceramicproductionand interactionsin Chavinde
Huantar.However,none of the conclusions presentedherecould havebeen reachedsolely on the
basis of neutronactivation.Petrographicandgeological datawereveryimportantin interpretingthe
chemicalresults,along with stylistic information.
By combining these different sets of data more
informationcan be extractedfrompaste analysis.
