Plagioclase microstructures and compositions as tracers of mixing processes in weakly to strongly peraluminous granodiorites and granites from the Serre Batholith (southern Italy)

摘要: The granitoids of the Serre Batholith make up middle portion an entire section late Variscan continental crust exposed in central Calabria. most felsic rock types consist two-mica K-feldspar megacrystic granodiorites and granites (BMPG), passing southward to (BMG), that grade further south Bt±Am (BAG). Microstructural features plagioclase from three granitoid units were studied detail An contents profiles obtained for selected crystals representative samples. Large (4-7 mm), medium (1-3 mm) small (
