South Africa’s history and economy has been built on its rich natural treasures of a number of precious metals, stones and minerals.
The country’s mineral deposits have been created over hundreds of millions of years through processes that are still not completely understood.
One of these processes, that has troubled scientists and geologists for years, is the origin of chromitite layers hosted by layered intrusions – a major source of chromium on our planet. This process has been a mystery for decades, as scientists tried to work out how layers of pure chromite form from magmas that are coming from Earth’s mantle. These are supposed to be rich in a mineral called olivine – not chromite.
