It is wider (> 24 km) and thicker (~ 15 m) of the fluvial sand body formed during the YD.
These channel deposits, together with extensive amalgamated crevasse-splay deposits, form an intricate network of fluvial sand deposits.
Interfingering fluvio-lacustrine deposits of the Baragoi paleo-delta provide insights into the lake-level history and how erosion rates changed during this time, as revealed by delta-volume estimates and the concentration of cosmogenic 10Be in fluvial sand.
Sediment clusters 2 and 3 show differences in carbonate content and, especially, in reactive iron, confirming that in the sand pit area a Holocene marine layer overlies Pleistocene fluvial sand.
The evidence includes erosion and deformation of glaciolacustrine sediment that we interpret happened during draining of the lake, desiccation cracks that formed during exposure of the lake bottom, and fluvial sand deposited as the lake began to refill.
