Abstract

Here, the AA. report on the occurrence of permafrost features in relation to lake development in the Tso Kar basin, Ladakh, throughout the last 20 000 years. These features appear to have been significantly influenced by the lake and its sedimentation history. The results are based on joint Indian-German field research carried out in the area since 2004. This included geological and geomorphological mapping, differential GPS measurements, drilling, echo-sounding and stratigraphic analyses, as well as remote sensing and GIS techniques. Regression of the lake with accompanying salinisation since about 4cal. kyr BP allowed permafrost aggradation. Permafrost mounds and thermokarst features are inferred to have continued to develop in the last 60 years
