Blue Barite with Chalcopyrite
Barium Sulfate, BaSO4
- Barite is a widespread, relatively common mineral which forms under low to moderate temperature conditions
in hydrothermal veins. It is also found in sedimentary rocks as replacements, veins and cavity fillings
formed by hypogene or meteoric solutions.
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.
