Abstract
The Kalkkop Crater Lake deposit formed as a result of a meteorite impact, and is situated ~51 km southwest of Graaff-Reinet in the Southern part of South Africa. The structure is about 650 m wide, and contains 90 m of lake deposits that are mainly carbonate precipitates. A 90 m sediment core from the Kalkkop Crater Lake was investigated using sedimentology, palynology and geochemical analysis. The KK1 core, along with the other two boreholes (KK2 and KK3), comprise of finely laminated and massive, structureless carbonates interrupted by debris flows from the crater rim.
