The Great Dyke is a prominent geological feature in Zimbabwe, stretching approximately 550 kilometers. It is a long, narrow ridge composed mainly of ultramafic rocks, which are rich in minerals. This unique formation is known for its significant deposits of platinum group metals, making it one of the richest mineral belts in the world. The Great Dyke was formed around 2.5 billion years ago during the Archean era. It runs from the Zambezi River in the north to the Save River in the south. The area surrounding the dyke is also home to diverse ecosystems and various wildlife, contributing to its ecological importance.
