Multi-shelled orbicular olivine gabbronorite from Leh, Jammu and Kashmir, Ladakh Himalaya

Abstract

We report here a multi-shelled orbicular olivine gabbronorite with anorthositic rims from Leh, J&K, India. The rock occurs as a transported boulder near Nimoo (12 degrees 95'33.40 '' N; 38 degrees 54'45.47 '' E) in Leh, over the Indus Group of sediments at an elevation of 3110 m, and is most likely derived from the Ladakh Granitic Complex. We present here the morphological details, and preliminary mineralogy and petrology of the orbicular rock.
