DeepChalla

East Africa

Fine sediment lamination in Lake Challa (East Africa), dating from three time periods during the last two glacial-interglacial cycles. Left: open core surface, CHALLACEA core sequence recovered in March 2005. Centre and right: view through core liner, DeepCHALLA core sequence recovered in November 2016.

... below the lake floor, with almost certain 100% coverage over the uppermost 121.3 meter (ca.150,000 years ago to the present) and at least 80% coverage in the lower part of the sequence, down to the lowermost distinct seismic reflector displayed in the project logo. This reflector represents a 2-meter thick layer of volcanic sand and silt deposited ca.250,000 years ago, and overlies silty lacustrine clays deposited during early lake development. As readily observed through the transparent core liners, Lake Challa sediments are finely laminated throughout most of the recovered sequence. Down-hole logging from 187 meter depth to the surface produced continuous profiles of in-situ sediment composition that confer an absolute depth scale to both the recovered cores and their three-dimensional representation in seismic stratigraphy.
