The Merensky Reef is a significant geological formation located in South Africa, primarily within the Bushveld Igneous Complex. It is renowned for its rich deposits of precious metals, particularly platinum, palladium, and gold. The reef is approximately 2 billion years old and is a key source of the world's platinum group metals. This geological feature is named after the geologist Hans Merensky, who discovered it in the early 20th century. The Merensky Reef is typically found at depths of 600 to 1,200 meters and is characterized by its unique mineral composition, making it a vital area for mining and economic development in the region.
