poldervaartite
Rare mineral that forms a series with Olmiite that has calcium replacing some of the magnesium. Like Olmiite, it is found only in the Kalahari Manganese Field of South Africa. Poldervaartite is much less common that perceived, with many specimens having been labelled as Poldervaartite in fact being Olmiite upon further analyis.
