Kalahari Manganese Fields

Situated in extremely well-preserved, 2.2 billion-year-old sedimentary rocks of the Transvaal Supergroup near Hotazel in the Northern Cape province of South Africa, the Kalahari Manganese Field is one of the geological and mineralogical wonders of the world. In addition to representing by far the largest-known land-based manganese deposit on Earth, the Kalahari Manganese Field is also the world’s top producer of ore in manganese metal tonnage. It also hosts a world-renowned, unique and varied assemblage of aesthetic collector’s mineral specimens that are often rare or unique.
