Attachment characteristics were assessed with an interview-based measure (Adult Attachment Prototype Rating [AAPR]) as well as an attachment self-report (Bielefeld Questionnaire of Client Expectations [BQCE]). Therapeutic factors were measured retrospectively with the Dusseldorf Therapeutic Factors Questionnaire and treated as an individual- as well as a hospital-specific characteristic. On an individual level, only the group climate factor independently predicted treatment outcome (i.e., Symptom Checklist-90-R Global Severity Index and Inventory of Interpersonal Problems mean). If simultaneously but separately included into a path model, analyses revealed independent significant effects of AAPR-Security and BQCE-Security on group climate. If modeled as a latent variable (common attachment security), a substantially higher proportion of group climate variance could be explained. Further analyses revealed interactions between particular therapeutic factors and attachment characteristics, indicating a particular importance of these therapeutic factors for different attachment categories.

The mineralization is hosted in the volcanic rocks of late Neoproterozoic and the detrital sedimentary rocks of the Lower Cambrian. A network of faults has affected this area; it is a brutalizing deformation with NW-SE, NE-SW, E-W, and NNE-SSW directions. NW-SE and NE-SW structures have a metallogenic significance. This tectonic canvas was used as a target of a mineralization vein with Cu, Ag, and Pb in this area. By combining geological, structural, and metallogenic characteristics, it can be assumed that the Cu-Ag-Pb mineralization of the Agdim-Ait Elfersi sector is linked to two major events. A late Pan-African event linked to the extensional tectonics of the late Neoproterozoic, responsible for the establishment of mineralization at the level of the basement, and then a late Hercynian-Atlasic event, which manife...

To Bou Azzer, the serpentinisation affected almost all of the ultrabasic rocks. Among the phenomena bound to the serpentinisation observed on the ground, we distinguish the magnesium deposits (Carbonated serpentinite). These magnesian deposits correspond to veins taken in serpentinized peridotites either realizes the contact between serpentinites and ultrabasic and basic cumulats. These veins of some centimeters a few meters away from power concentrate essentially in the regions of Ait Ahmane, Ingujjem and Ambed and are formed by massive or brecciated magnesite or in cauliflower. The petrography ic and mineralogical studies of the deposits of magnesite of Bou Azzer, reveal mainly two different mechanisms: The replacement metasomatic in situ of the serpentine and the filling of fracture by circulation of...

The Zgounder inlier constituted at the base by metasedimentary basement rocks of the Early Ediacaran Saghro Group which were affected by two Pan-African deformational phases and contain tholeiitic mafic sills interstratified with a metasedimentary formation of Late Cryogenian to Early Ediacaran age emplaced in an intraplate rift zone (continental tholeiites). Volcanic-detrital strata of the Bou Salda Group of Early Ediacaran age overlay the sediment formation of Saghro Group and exhibit a calc-alkaline geochemical signature. The Saghro and Bou Salda groups are overlain by volcanic rocks or intruded by subvolcanic and plutonic formations of Late Ediacaran age (Ouarzazate Group). The volcanic rocks consist of the following: (1) andesite lava containing plagioclase (andesin...

The genesis of those mineralizations is result of both hydrothermal and tectono-magmatic processes.The results show that a primary paragenesis of magmatic origin with pentlandite, chromospinelle, and cobaltiferous and nickeliferous magnetite has been highlighted in Ambed massive where the serpentinization of ultramafic rocks is partial, and it is probably associated with Fe sulphides. However, the mineralogical assemblages identified in Aghbar and Bou Azzer East massive where serpentinization is total are composed on secondary minerals of polydymite cobaltiferous, millerite cobaltiferous, orcelite and magnetite co...

It consists of ultramafic rocks, cumulate gabbros, sheeted dikes, pillow lavas, and an overlying volcano-sedimentary sequence. Three main tectonic slices of sheeted dike complexes are studied in detail along three rivers, exposing well preserved outcrops where individual dikes are clearly distinguishable from the intruded host rock (Assif n’Tinzla, Assif n’Tasriwine, and Assif n’Iriri). Sheeted dikes of the Khzama ophiolitic complex are basaltic to andesitic in composition, displaying a clear sub-alkaline nature. We identify two sets of dikes that originate from lower High-Ti series (HTS) lavas and overlying upper Low-Ti series (LTS) lava. The immobile trace-element signatures of these rocks point to a genesis on a backarc environment with magmas sourced in a supra-subduction zone (SSZ) at the spinel peridotite zone. The obtained SHRIMP U-Pb data of the gabbro represent...

In order to constrain geodynamic events related to rifting and convergence and their stratigraphic records, a radiometric study was carried out on the volcano-sedimentary Tachdamt and Bleïda Formations. The volcaniclastic deposits of Tachdamt Fm. yield an age of ca. 883 Ma and provide a new constraint for the timing of the subaqueous volcanic eruption and the initiation of rifting in the Anti-Atlas. This age is ~100 my older than the previous age of 788 ± 10 Ma obtained from Rb/Sr isotope dating (Clauer, 1976). Available zircon data from the interbedded clastic deposits from Tachdamt Fm. indicate major shifts in provenance during the rifting with sediments sourced from the WAC and a nearby Grenvillian terrane. Detrital zircon ages from metasiltstones of Bleïda Fm. set a maximum depositional age at ca. ...

Pressure and temperature estimates obtained using a NaCaKFMASHT phase diagram (pseudosection) and garnet core and rim compositions predict that garnet growth began at ∼0.72 GPa and ∼615 °C and ended at ∼0.8 GPa and ∼640 °C. A bulk garnet Sm-Nd age of 647.2 ± 1.7 Ma, calculated from a four point isochron that combines whole rock, garnet full dissolution and two successively more aggressive partial dissolutions, provides a precise date for garnet formation and regional metamorphism. The age is over 15 million years younger than a previous age estimate of regional metamorphism of 663 ± 13 Ma based upon a SHRIMP U-Pb date from rims on zircon from the Iriri migmatite. The new data provide further constraints on the age and nature of regional metamorphism in the Anti-Atlas mountains and emphasizes that garnet growth during regional metamorphism may not necessarily coincide with magmatism/anatexis which predominate the signature witnessed by previous U-Pb studies. The ability to couple PT estimates for garnet formation with high precision Sm-Nd geochronology highlights the utility of garnet studies for uncovering the detailed metamorphic history of the Anti-Atlas mountain belt.

Situated to one hundred kilometers south-west of Ouarzazate, the Bou Azer inlier runs along the Anti-Atlas Major Fault. The Precambrian rocks which outcrop in the inlier represent a reference in the Morocco geology to understand the Precambrian events of the Anti-Atlas. Its interest is increased by the occurrence of an ophiolitic complex and by the metallogenic richness of this inlier. The Aït Ahmane map is composed of a Tonian to Ediacaran basement overlain by an upper Ediacaran volcanosedimentary cover (Ouarzazate Group), and by a lower Paleozoic sedimentary cover. These rocks recorded successive tectonic phases, panafrican, hercynian and atlasic. The geological survey of the formations with petrographic, geochemical, and geochronological study allows us to distinguish several lithological units crosscutted by few magmatic intrusions. The Tachd...

More precisely, the map fits into a rectangle in which the sedimentary cover of late Neoproterozoic to early Paleozoic forms a broad syncline occupying the major part of the geological map. Only the northern edge of the map consists of Proterozoic rocks, especially in the Izazen-Azaghar and Agadir Melloul Imoula inliers. The Paleoproterozoic rocks are the oldest formations in these inliers. They are affected by Eburnean orogenesis, and include (I) an ancient metasedimentary basement and (II) intrusions of various types of granitoid (intermediate to acid chemistry) which developed a more or less important contact metamorphism in the surrounding metasediments. Moreover, this Paleoproterozoic inlier hosted a whole network of basic to intermediaries...
