Vote for your favorite mineral in #MinCup26! - Sphalerite vs. Anorthite Both zinc ore Sphalerite and calcium plagioclase feldspar Anorthite have perfect cleavage that will split cleanly if you hit them with a hammer, but only one can claim a larger split of your votes!
In polished sections, asisite is seen to occur as euhedral to subhedral lathlike grains in colorless barite in the interstices of coarsely crystalline hematophanite. Less perfect grains are intergrown with other minerals and partially fill fractures and cavities in the hematophanite. Other minerals present in the barite matrix are jacobsite (containing inclusions of hematite and native copper), blades of molybdophyllite, and serrated laths of chlorite.
