Introduction
Two main principal aspects for the genesis of
porphyry copper deposits have been determined.
The first genetic model concerns the petrologic
and geochemical processes and the other relates
the genesis to crustal deformation and
geodynamic conditions (Kesler, 1997). Recent
studies (e.g., Padilla Garza et al., 2001) show
that the generation and emplacement of porphyry
copper deposits may not only be dependent on
magmatic and hydrothermal processes, but also
that the regional and local tectonic setting plays
an important role. Therefore in determining the
suitable setting for emplacement of copper and
other porphyry intrusions, determination of
location of partial melting of the lower crust,
generation of batholiths, and their volatile-rich
derivative intrusions in the crust seems to be
necessary (Carranza and Hale, 2002). Almost all
porphyry copper deposits in Iran are located in the
Urumieh-Dokhtar magmatic belt. These deposits
show distinct spatial and temporal relationship
with Miocene granodiorite plutonic rocks
emplaced along strike slip faults (Mehrabi et al.,
2005). Accordingly, the tectonic setting of ore
deposits seem to be the most important factor for
regional exploration of porphyry copper systems
(Vearncombe and Vearncombe, 1999). There are
several methods for analysis of distribution of ore
deposits. In this research the role of structural
control in the spatial distribution of porphyry
deposits has been studied using Fry and Fractal
methods. Here, the Fry method is used as a
complementary method for Fractal analysis.
Materials and methods
Fry analysis is a self-adaptive method that is used
for point objects. Fry analysis offers a visual

approach to quantify the spatial trends in groups
of point objects. Fry analysis can also be used to
search for anisotropies in the distribution of point
objects. More specifically it can be used to
investigate whether a distribution of point objects
occurs along linear trends, and whether such
linear trends occur at a characteristic spacing.
There is 37 and 42 copper point's index in the
Khezr-Abad and Shar-B-Babak areas. The Fry
patterns of copper index for two areas were
determined with application of Dot Proc software.
Fractal analysis is another technique for
determination of regional distribution of faults. In
this research the fractal dimension of joints and
faults was determined in different locations using
box-counting fractal method and drawing the
logarithmic graphs.
Results
- The major faults show NW/SE trends in the
Khezr-Abad area. They have a similar trend with
Dehshir-Baft fault. Other sets of faults show
NE/SW trend. These faults are younger than the
Dehshir-Baft and release sinistral sense of shear.
- Intrusion of two intrusive bodies leads to the
accumulation of strike-slip faults in the vicinity of
intrusive rocks. In this region faults and joints
mainly show NW/SE and NE/SW trends.
- The results of Fry analysis show that the
mineralization in the Khezr-Abad occurred in the
Cretaceous (and younger) rocks with NE/SW and
NW/SE orientations. In the other words, these
areas of mineralization are mainly related to the
secondary faults or (P faults) in the pull basins
and cross cutting points of these faults which have
similar strike with the Dehshir-Baft fault. NE/SW
mineralization is probably related to the tensional

stress direction or faults having the general trends
of central Iran structures.
- The calculations of fractal dimension show that
the southeastern parts of the Khezr Abad have
higher amounts of fractal dimension (Db=
1.7002). Also there is a relatively higher copper
index in this part, indicating a logical relation
between fault structures and mineralization.
-The generated maps indicate that the
mineralization in the Shahr-e-Babak area occurred
at the intersection of faults and volcanic system
and the Fry analysis shows a NE/SW and NW/SE
trend of ore concentration.
- Northwestern parts of the Share-e-Babak show
higher fractal dimension (Db= 1.748) that occurs
in the areas with more volcanic rocks and copper
indexes.
- Results show that the porphyry copper
mineralization mainly occurs near the great faults
and related to the fault structures and shear zones
in the Urumieh-Dokhtar structural zone. In the
other word fault lineaments are the main factors in
the local concentration of the ore deposits.
Discussion
The Study of geometry and mechanism of faults
related to porphyry copper deposits is very
important for determining the suitable location of
ore concentration (Zarasvandi, 2004). For
example, shear zones, pull apart basins, and step
over along the strike slip faults are proper
locations for concentration of porphyry ore
deposits (Carranza and Hale, 2002). In this
research the Khezr-Abad and Shahr-e-Babak areas
have been studied. Plotted rose diagrams show the
main role of the Dehshir-Baft shear zone for
generating the joints and faults in the KhezrAbad
area. In this area faults with NNW/SSE and
NW/SE trends are the main direction of ore
concentration. They are mainly related to the
Dehshir-Baft fault. NE/SW faults show sinistral
sense of shear and generally are younger than
22
before mentioned sets. Finally the latest fault sets
show N/S trend. The Shahre-e-Babak area is
mainly dominated with Eocene igneous rocks.
Volumetrically, andesite units are more abundant.
Rose diagrams represent the existence of two
main conjugate fault sets with NW/SE and
NE/SW trends. The main copper indexes are
located in the intersection of volcanic rocks with
these two fault sets. Also the results of Fractal
analyses reveal the higher Fractal dimension in
the Northwestern part of the Shahr-e-Babak area.
In the other words the most density of joint and
faults occurred in this region.
