Limpopo Belt

The Limpopo Belt is a special area located in South Africa and Zimbabwe. It runs in an east-north-east direction and connects two very old pieces of Earth's crust, called the Kaapvaal craton to the south and the Zimbabwe Craton to the north. This belt is made up of high-grade metamorphic rocks, which means the rocks have been changed by heat and pressure over a very long time.

The rocks in the Limpopo Belt went through a long cycle of change and movement, ending about 2.0 billion years ago. After this time, the nearby areas, called massifs, became stable. The belt itself has three main parts: the Central Zone, the North Marginal Zone, and the South Marginal Zone. These parts show how Earth's surface has been shaped and changed over millions and millions of years.

Ca. 3.2-2.9 Ga Limpopo Central Zone

The Limpopo Belt in southern Africa is a wide zone of changed rocks. It separates two large, old land areas called the Kaapvaal and Zimbabwe cratons. The belt has stretchy areas where the earth's layers moved and changed over time.

The rocks in the central part of the Limpopo Belt went through three main time periods. The first two periods, about 3.2 to 2.9 billion years ago and around 2.6 billion years ago, were mostly about hot, molten rock forming. The third period, around 2.0 billion years ago, happened under very high heat and pressure. This caused some of the rocks to melt partly. These changes give us clues about how the earth looked and acted long ago.
