The deposition and development of the Kalahari Group sediments, Central Southern Africa

Abstract

Kalahari Group sediments cover 2.5 × 106 km2 of central southern Africa. This paper analyses their deposition and development by integrating geological and geomorphological evidence. The post-Gondwanaland tectonic evolution of the sub-continent, drainage development, climatic change and post depositional modification are all identified as important for the development of the Kalahari Group. It is concluded that local, regional and sub-continent wide influences have all played important roles. Consequently, caution should be implemented when attempting to correlate sedimentary units in different areas.
