Geology of the Kali Gandaki Supergroup of the Lesser Himalayas in Nepal.

Abstract

The Kali Gandaki Supergroup is extensively distributed in the Mahabharat Range and the Midland of the Lesser Himalayas in western Central Nepal. It is a thick sequence attaining >10 km in thickness and ranging in age from Late Precambrian to early Palaeozoic, and is unconformably overlain by the Tansen Group of Gondwana rocks. There is no stratigraphic break throughout the whole sequence. The Kali Gandaki Supergroup is divided into three groups. The Lesser Himalayas in the study area is structurally divided into two belts, a complexly folded outer belt and block-faulted inner belt by the active right-lateral Bari Gad Fault. -from Author
