Cleavage of pyrite
WebThe most obvious physical properties of chalcopyrite are its brassy yellow color, metallic luster, and high specific gravity. These give it a similar appearance to pyrite and gold. Distinguishing these minerals is easy. … WebCleavage: Cleavage is defined as how a mineral breaks. If the mineral breaks along straight lines then it has cleavage. If the mineral breaks with jagged, non-straight edges, then it has fracture. Pyrite's cleavage is very indistinct which means is not clearly or sharply faint.

WebPyrite can form cubic crystals (Figure 2.6.4b), but can also form crystals with 12 faces, known as dodecahedra (“dodeca” means 12). The mineral garnet also forms dodecahedral crystals (Figure 2.6.4c). ... Cleavage … WebThe mineral pyrite, or iron pyrite, is iron sulfide, FeS 2. It has isometric crystals that usually appear as cubes. The cube faces may be striated (parallel lines on crystal surface or cleavage face) as a result of …
