WebGeometric Models. Cleavage means the separation by breakage of a mineral into fragments across planes of weakness in chemical bonds. Because the orientation of ions and molecules in a mineral is geometrical and repetitive, minerals fragment into the same geometric shape - for example, bigger cubes and smaller cubes. http://webmineral.com/data/Gypsum.shtml

Galena exhibits cubic cleavage, which means that it has three internal planes of weakness along which it can be broken and these planes are at right angles to one another. In contrast, graphite only has … WebChalcopyrite 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. graphic arts supply minneapolis
