Factors responsible for driving the glaciation in the Sarchu Plain, eastern Zanskar Himalaya, during the late Quaternary
ABSTRACT Detailed geomorphological investigation supported by field stratigraphy and optical dating enabled us to identify three major events of glaciation in the eastern Zanskar Himalaya (Sarchu Plain). The oldest and most extensive glaciation is the Sarchu Glaciation Stage‐1 (SGS‐1) that pre‐dates...
