Zircon is often used to study granites (sensu lato) and continental crust because it is very resistant and can be analyzed for various isotope systems that provide time and source information about their parental melts. Granites with different petrol

Les effets territorialisants des processus de géopatrimonialisation sont analysés en région Auvergne-Rhône-Alpes (France). Ils permettent d’identifier au sein de cette région un certain nombre de géoterritoires, caractérisés par l’identif

International audience; Mashhad granitoids and associated mafic microgranular enclaves (MMEs), in NE Iran record late early Mesozoic magmatism, was related to the Palaeo-Tethys closure and Iran-Eurasia collision. These represent ideal rocks to explor

The calc-alkaline granitoids of the central Sierra Nevada batholith are associated with abundant mafic rocks. These include both country-rock xenoliths and mafic magmatic enclaves (MME) that commonly have fine-grained and, less commonly, cumulate tex

Granitoids are divided into several types according to their mineral assemblages, their field and petrographical features, and their chemical and isotopic characteristics. This typology complements most of the recent classifications because it is not

Plagiogranites are relatively abundant in the NE part of the Albanian ophiolite belt. They are commonly associated with subvolcanic and volcanic rocks (low Ti basalts, andesites, dacites and boninites). The study of the Shemri and the Kimez units ill

Thermal, mechanical and chemical exchange occurs between felsic and mafic magmas in dynamic magma systems. The occurrence and efficiency of such exchanges are constrained mainly by the intensive parameters, the compositions, and the mass fractions of

Comparison of the twenty most frequently used petrogenetic classifications of granitoids is summarized using petrography, nature and abundance of enclaves, mineralogy, major and trace element, and isotope geochemistry. This comparison indicates consi

Two-mica monzogranites to leucogranites and biotite-rich, cordierite-bearing tonalites to monzogranites form two distinct groups of peraluminous granitoids. They can be distinguished by mineral and rock associations and by the variation of their pera

We examined the Rb-Sr and Sm-Nd systematics of three different, high-level to subvolcanic granitoid plutons and their microgranular enclaves. The host granitoids are adamellites and grano-diorites, while the enclaves are mostly microtonalites with ig
