Chalcopyrite is a striking, bright yellow, metallic mineral that occurs in nearly all sulfide deposits. Initially, it may be easy to confuse chalcopyrite, or copper pyrite (CuFeS2), with pyrite (FeS2), but the two can be distinguished by their relative hardness and chalcopyrite’s iridescent tarnish.

The hardness tests reveal two key ...

The Mohs hardness scale is a qualitative test that measures the hardness of a mineral by its ability to visibly scratch softer minerals. The scale isn’t perfect, but it’s a great tool for quick identification of rocks in the field. Here a look at the scale, how ordinary minerals and objects rank, and how to perform the Mohs test.Hardness: 2.5: Specific gravity: 2.16: Cleavage: Perfect cubic {100} Fracture: Conchoidal: Luster: Vitreous: Transparency: Transparent to translucent: Streak: White: Optical Properties: PPL: ... Ragged halite crystal on a grain of sand from Satellite Beach, FL Halite in Thin Section. Stay tuned for explorable images! Halite, plane polarsHalite: Halite has distinct cubic cleavage, and although it may resemble the clear rock crystal variety of quartz, the two can be distinguished by halite s distinctive taste, cleavage and softness. Quartz cannot be scratched by most metal implements and does not display any cleavage. Chemically, the difference between the two is that hard water contains calcium and magnesium ions, while soft water does not. Soft water is easier to lather with than hard water is.Pyroxene properties. Chemical Composition. (NaCa) (Mg,Fe,Al) (Al,Si)2O6– Sodium Calcium Magnesium Iron Aluminum Silicate. Color.
