Geological Formation of South Africa

The original source of these gold particles, however, remains something of a geological mystery. Around 2.7 billion years ago, the Kaapvaal Craton collided with the Zimbabwe craton to the north. This created a mammoth mountain range that rose up along what is now called the Limpopo Mobile Belt. It also resulted in a great flood of lava that ...

How Diamonds are Formed Cape Town Diamond Museum

HOW DIAMONDS ARE FORMED. Diamonds were formed over 3 billion years ago deep within the Earth’s crust under conditions of intense heat and pressure that cause carbon atoms to crystallise forming diamonds. Diamonds are found at a depth of approx. 150-200km below the surface of the Earth. Here, temperatures average 900 to 1,300 degrees Celsius ...
