Dolomite Speckled with Chalcopyrite
Calcium Magnesium Carbonate CaMg(CO3)2
- Dolomite is most common as a sedimentary rock-forming mineral in rock known appropriately as dolomite.
It is abundant in dolomitic limestones and as a gangue mineral in hydrothermal mineral deposits.
Copper Iron Sulfide, CuFeS2
- Chalcopyrite occurs in appreciable quantity in nearly all copper sulfide deposits. It is the most important
ore mineral of copper. Chalcopyrite is predominately of primary origin in veins and replacement bodies, as
disseminated particles in a variety of rock types and in contact metamorphic zones.
