Abstract

The EOCENE CHAPEDONY METAMORPHIC CORE COMPLEX, is located in western part of the Posht-e-Badam block. This complex is consisting of migmatite, gneiss, amphibolite, marble, micaschist and various types of granitoids. In middle part of this complex (Kalut-e-Chapedony), an EOCENE granitic rock unit cross cuts the other rocks. The minerals of this granite are plagioclase (An9Ab87Or4), potassium feldspars (orthoclase), quartz, euhedral garnet (Alm77Sps13Prp9Grs1), zircon, apatite, fibrolitic sillimanite and muscovite. Petrology and geochemical studies reveal calc-alkaline, peraluminous and S-type nature of the studied granites. Chondrite-normalized REE patterns represent evident negative anomaly of Eu and low values of the REEs. Continental crust and North American shale composite (NASC) - normalized multi-elements spider diagrams indicate trace elements depletion. These granites are formed by melting of continental crust sedimentary rocks, resulted by emplacement of mantle-derived magma at the bottom of continental crust which formed the CHAPEDONY METAMORPHIC CORE COMPLEX. The source rock of these granites should be a clay-rich sedimentary rock with low amount of plagioclase and CaO/Na2O ratio.
