Kalkkop is an
Eastern Cape Province of South Africa. The name is derived from two Afrikaans words, namely "kalk" meaning limestone and "kop" meaning head.[1]
The meteorite impact occurred about 250,000 years ago (Pleistocene) on what is now the flat Karoo landscape. It left a crater 640 metres in diameter and a few hundred metres deep. Over time, draining water left a limestone deposit 88 metres deep. This lies over a breccia layer a further 210 metres deep. Only a weathered circular ridge is still visible at the surface.
This is one of four confirmed impact sites in South Africa and six within the Southern African region.[2]
