what type of rocks are calcite, quartz, halite, and pyrite
In calcite and quartz veins, pyrite is commonly associated with chalcopyrite and other sulfide minerals and metallic ores. Pyrite oxidizes to other iron sulfate minerals that in turn alter to limonite, so the presence of a weathered ârustyâ limonite layer may indicate the presence of pyrite in the underlying rock.lthough it is not a significant rock-forming mineral, pyrite is very widespread and a common accessory mineral in many rock types. In igneous rocks, pyrite may be disseminated throughout the rock or concentrated in layers if the magma cooled slowly enough for crystals to settle out.
Halite /ËhaelaÉªt/ , ËhÃ¦laÉªt commonly known as rock, salt is a type of, salt the mineral form of sodium (Chloride Na). Cl halite forms isometric. Crystals the mineral is typically colorless or, white but may also be light, blue dark, blue, purple, pink, red, orange yellow or gray depending on the amount and type of. impuritiesalite occurs in vast beds of sedimentary evaporite minerals that result from the drying up of enclosed lakes, playas, and seas. Salt beds may be hundreds of meters thick and underlie broad areas.
