Definition

Proper noun A major geological formation and region in the northeastern part of South Africa, specifically within the southern area historically known as the Transvaal. It is characterized by a rocky ridge and is globally significant for containing extraordinarily rich mineral deposits, most famously gold, which led to the establishment of the city of Johannesburg and a series of large-scale gold mines. The region also contains substantial deposits of coal and manganese.

Usage

The term "Witwatersrand" is used primarily as a proper noun to refer to the specific geographical region and its geological basin. It is a central term in the economic and historical context of South Africa. * The discovery of gold on the Witwatersrand in 1886 triggered a massive gold rush. * Johannesburg is located on the Witwatersrand ridge. * The Witwatersrand Basin is one of the world's largest gold-producing areas.
