Sphalerite is found in a variety of mineral deposit types, including sedimentary exhalative, Mississippi-Valley Type (MVT), and volcanogenic massive sulfide deposits. Many minable deposits of sphalerite are formed when the hydrothermal activity or contact metamorphism brings hot, acidic, zinc-bearing fluids in contact with carbonate rocks.In addition to their concentrated occurrence in ore deposits and areas of mineralization, a limited number of sulphide minerals are found as accessory minerals in rocks. However, only pyrite, pyrrhotite, galena, sphalerite, chalcopyrite, and possibly the binary copper sulphides of the chalcocite family could be classed as rock-forming minerals.Mineralogy.

Some of them can glow a particular color, but others can be in a rainbow of possible hues.Table_5. CLEAVAGE. The way a mineral breaks is determined by the arrangement of its atoms and the strength of the chemical bonds holding them together. As these properties are unique to the mineral, careful observation can aid in mineral identification. Cleavage: mineral breaks along parallel, flat surfaces (cleavage planes).

A common rock-forming mineral found in felsic igneous rocks, pegmatites and metamorphic rocks, muscovite is the lightest-colored member of the mica mineral group. Micas are a group of sheet silicate minerals distinguished by their perfect single cleavage. This cleavage allows mica minerals to be easily split into thin parallel sheets.

Zinc sulfide occurs as two polymorphs, cubic sphalerite and hexagonal wurtzite. Sphalerite is the stable phase at low temperatures and is a fairly common trace mineral in sulfidic sediments. It forms as a discrete solid phase since Zn is not incorporated to any significant extent within sedimentary pyrite (Luther et al., 1980, Morse, 1994 ).The other mineral that can carry significant indium in base metal ores is chalcopyrite (e.g., Gaspar, 2002).Concentrations of indium are, however, lower than in co-existing sphalerite (e.g., Cook et al., 2011) where the two minerals co-exist, suggesting a strong fractionation into the zinc sulphide.Chalcopyrite can potentially account for a …Sphalerite occurs as red to black crystals with a euhedral form or scattered as smaller pieces in bedrock.
