Dwyka Group

The Dwyka Group is a geological formation consisting mainly of ancient glacial deposits from the late Carboniferous to early Permian periods, around 300 million years ago. These deposits include tillites, sandstones, and shales formed by glaciers and ice sheets that once covered parts of southern Africa. The Dwyka Group is important for understanding Earth's past climate and glacial history, and it often serves as a source rock for hydrocarbons like oil and natural gas. Its study provides insights into the ancient environment and the movements of prehistoric ice sheets.
