Volatile-assisted intrusion and autometasomatism of leucogranites in the Khumbu Himalaya, Nepal

Abstract:

Leucogranite crops out in the upper Imja Khola, Khumbu Himalaya, Nepal, where it makes up approximately 50% of the exposed bedrock. Leucogranites and their associated aplite-pegmatites typically intruded as concordant sills, millimeters- to kilometers-wide.
