Type Occurrence of Sabieite
Place of Conservation of Type Material:
South African Geological Survey Museum, Pretoria, South Africa.
Geological Setting of Type Material:
Formed by the oxidation of pyrite, which interacts with ammonia produced from the decay of organic matter. Likely to form if the pH is below one.
