Biogenic silica deposition in Lake Malawi, East Africa over
2011-4-1 · Abstract. We report a 150,000 year record of the abundance of biogenic silica (BSi) in drill cores from the northern and central basins of Lake Malawi. The periods of highest diatom burial at both sites occurred around 65–69 and 51–60 thousand years ago (ka) after the termination of prolonged, intense drought in the region.
