Bahadur Singh Kotlia, Ingelore Hinz-Schallreuter, Roger Schallreuter & Jürgen Schwarz
About 35,000-40,000 yr BP, an episode o f neotectonic activity on the Indus Suture Zone created a lake at Lamayuru (Ladakh) that has preserved an over 105 m thick sequence of fluvio-lacustrine deposits. The lacustrine horizons (carbonaceous muds) and a number of carbonate-rich strata interlayered with clay/silt/sand have yielded freshwater ostracods, gastropods and charophytes. A total of nine fossiliferous horizons are located. The prominent ostracod taxa are llyocypris (I. gibba and I. bradyi), Eucypris and...
