Reactivation of faults and alternation of competent Normal Faults. (thicks Ordovician series, Silurian limestone and Devonian limestone) and incompetent levels (Silurian shales and Devonian marls) have an important role in the deformation of the TTR anticline during the NE-SW Variscan shortening. Our work based on lineaments extraction using a Landsat 8 OLI combined with some geological cross sections, shows a N130° major fold corresponding to TTR anticline. This big fold shows internal N130°, N95° and N20° minor folds. This structure indicates that the TTR area was formed in the hinge between the Anti-Atlas and the Ougarta belts. A number of these folds are the consequence of the underlying Precambrian faults reactivation and alternation of competent and incompetent levels. Brittle tectonics is dominated by NE-SW normal faults which Received Date: 19.07.2018 result from the NE-SW shortening consequence of the Gondwana and Eurasia continents collision. Accepted Date: 16.01.2019 Consequently, the mineralization of TTR is necessarily related to late or post-Variscan orogeny. 1.

Matieland 7602, South Africa ABSTRACT The Lu-Hf isotopic composition of detrital zircons has been used to investigate the crustal evolution of the northern part of the West African (raton (WAC). The zircons were separated from six samples of siliciclastic sedimentary rocks from the main Neoproterozic stratigraphic units of the Anti-Atlas belt, from the SiIWa and Zenaga inliers. The data suggest that the north part of the WAC formed during three cycles of juvenile crust formation with variable amount of reworking of older crust. The younger group of zircons, with a main population clustering around 610 Ma, has a predominant juvenile character and Keyworili: evidences of moderate mixing with Paleoproterozoic and Neoarchean crust, which supports that most Anti-Atlas belt igneous and metamorphic rocks where zircons originally crystallized were formed in an ensialic mag­ Morocco Hfisotopes matic arc environment. The group of zircons in the age range 1.79-2.3 Ca corresponds to the major crust Detrital zircon forming event in the WAC: the Eburnian orogeny.

All of the ore deposits are located within a crustal block located at the intersection between two major shear zones and are characterized by a sustained and long-lived magmatic activity. The ore deposits are located within second-order shear zones, which played an important role in controlling the geometry of the mineralization. The mineralization lacks the unequivocal textural and structural features that are indicative of a sedimentary or diagenetic origin, and a syntectonic to late-tectonic pyrite-rich assemblage is superimposed on an earlier, pretectonic to syntectonic pyrrhotite-rich mineralization. Each deposit has a distinctive pyrrhotite sulfur isotopic signature, while the sulfur isotopic signature of pyrite is similar in all deposits.
