AMIS0564 Cu 1.41% Au 0.12 g/t Carbonatite Palabora South Africa
Origin of Material
This standard was made using ore sourced from Palabora Mining Company. The Palabora alkali carbonatitic massif is an ovoid bicentered alkaline ring complex with a carbonatite core which was intruded as a vertical pipe into Archean granite prior to 2.06Ga. The Palabora complex is unique in that it hosts the only economic copper sulphide carbonatite orebody in the world.
Approximate Mineral and Chemical Composition
The host rocks are carbonatite and foskorite. Chalcopyrite is the most abundant ore mineral followed by bornite. Chalcocite is a subsidiary sulphide in the foskorite. Other sulphides are valleriite, cubanite and pyrrhotite (minor). Other important mineral by-products are titaniferous magnetite and apatite. Uranothorite is also recovered.
