The Godhra-Chhota Udepur (GC) sector (west-central India) is the zone of convergence between two crustal-scale accretion zones, i.e. N/NNE-striking Aravalli Delhi Fold Belt (ADFB) against E-striking Central Indian Tectonic Zone (CITZ). In this study, we demonstrate orogens welded during Early Neoproterozoic. GC sector, recumbently folded basement gneisses, shallow-dipping granitoid mylonites an...

Abstract Hydrothermal veins and altered feldspar are evidence for fluid circulation in granitic rocks the continental crust. The hydrothermal alteration of affects deformation behavior granitoids, especially if it occurs before orogeny. Geochronology can establish timing to determine this fluid-driven plays a role crustal deformation. Although existing dating techniques cannot be applied direct...

The Açdif gold deposit is located in the Zenaga Inlier (central Anti-Atlas), approximately 120 km southwest of city Ouarzazate. It hosts mineralization associated with a shear zone affecting metamorphic and magmatic formations Eburnean basement. mainly consists alternating micaschists, augen gneisses, orthogneiss. These crystalline rock assemblages are intruded by variety granitoids. Azguemerzi...

The southern Ferkessédougou batholith in the center-west of Côte d’Ivoire is study area. geology this area includes granitoids (granodiorite, two-mica granite, biotite granite and muscovite granite) metasediment panels. Petrographic studies were coupled with geochemical analyzes on whole rock order to provide new elements structural evolution portion West African craton. data show that basement...

The N/NNE-striking Aravalli Delhi Fold Belt (ADFB) and the E-striking Central Indian Tectonic Zone (CITZ) converge at Godhra-Chhota Udepur (GC) sector, west-central India. Analyses of mesoscale deformation structures metamorphic phase equilibria in basement supracrustal rocks are integrated with geochronological-geochemical data (accompanying article) to address dynamics Early Neoproterozoic CI...

The Ghohroud granitoids (GG), containing mafic microgranular enclaves (MMEs) are located in the central part of Urumieh-Dokhtar Magmatic Arc (UDMA) Iran. They associated with subduction-related magmatism Alpine-Himalayan orogenic belt. GG comprised a variety intermediate and felsic rocks, including tonalite, granodiorite, granite, diorite porphyry monzodiorite. MMEs gabbroic tonalite compositio...
