The Granitoids of Pindar-Sarju-Ramganga and Goriganga Valleys of Higher Kumaun Himalaya
View through CrossRef
Abstract
In the Higher Kumaun Himalaya granitoids are widely distributed and occur as bands, lenses or sheet-like bodies. They include different varieties of gneissic granites (schistose, foliated, augen and porphyroblastic). The field, petrographic as well as chemical data indicate that the granitoids of Kumaun Higher Himalaya are formed due to metasomatic transformation of metasediments by alkalirich emanations. The geochemistry of these reveal their calc-alkaline, peraluminous, S-type nature and compositionally mainly represent granite. Trace elements discriminate the granitoids in the syncollisional environment.
