Pan-African orogeny

Also known as: Pan-African episode, Pan-African event

Quick Summary

The Pan-African orogeny was a major mountain-building event that occurred in Africa between approximately 950 and 550 million years ago. This thermotectonic event formed long fold belts, such as the Mozambique belt along the east coast of Africa, and the Damara and Katanga belts in southern Africa. These belts resulted from continental collisions, where sedimentary and volcanic rocks deposited in deep basins were deformed, metamorphosed, and uplifted into mountain ranges. The Arabian-Nubian Shield in northeastern Africa also experienced significant volcanic and granitoid activity during this period, similar to modern island-arc systems. This orogeny played a crucial role in shaping the African continent's geological structure.12
