South Africa's Minerals
South Africa is the world’s top producer of platinum, used in everything from jewelry to catalytic converters. Most of it comes from a geological formation the size of West Virginia, called the Bushveld igneous complex, created two billion years ago as molten lava from Earth’s mantle bubbled to the surface and cooled. Lamont-Doherty graduate student Jill VanTongeren is traveling through the Bushveld collecting rocks to learn more about how this unique and mineral-rich region formed. Read about her work here.
