Three intrusive granitoid bodies from northwest Saveh, central Iran, are embedded in volcanic sedimentary rocks of the Eocene,forming isolated small outcrops: Khalkhab quartz monzodioritic units (SiO2: ~52-57 wt %) to the northwest, Neshveh granodioriticunits (SiO2: ~62-71 wt %) to the northeast, and Selijerd granodioritic units (SiO2: ~63-69 wt %) to the southeast. The Khalkhab unit iscomposed...

Kahang Cu Porphyry deposit is situated in the central part of a major Iranian magmatic belt, Urumieh-Dokhtar, in central Iran.There are several sub-volcanic stocks (e.g., porphyric granitoids rocks, quartz monzonite, diorite and monzodiorite-monzogranite)within Eocene volcanic and pyroclastic rocks consisting of basaltic, trachy-andesite and dacitic rocks. Hydrothermal alterations at the Kahang...

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...

The mineral system concept, which combines integrated information from all kinds of geological and geophysical studies, is a very useful approach to predict locate structures lithologies potentially associated with gold mineralization at scales (i.e., upscaling craton-to district-to camp-to deposit-scale). This demonstrated in this study where the Yaou deposit, located French Guiana within Rhya...

The origin of ferroan A-type granites in anorogenic tectonic settings remains a long-standing petrological puzzle. proposed models range from extreme fractional crystallization mantle-derived magmas to partial melting crustal rocks, or involve combination both. In this study, we apply whole-rock chemical and Sm-Nd isotopic compositions thermodynamically constrained modeling (Magma Chamber Simul...
