Compositionally and.Halite: Halite has distinct cubic cleavage, and although it may resemble the clear rock crystal variety of quartz, the two can be distinguished by halite s distinctive taste, cleavage and softness. Quartz cannot be scratched by most metal implements and does not display any cleavage.Rock salt is a sedimentary rock primarily composed of halite. Halite is a mineral of sodium chloride (common salt), NaCl. Rock salt is usually white or colorless. However, impurities in the rock salt can make it appear light blue, pink, purple, yellow, orange, or gray. Colorless salt is rated the purest as it doesn’t contain any impurities.Sedimentary rocks Chemical sedimentary rocks form when minerals precipitate from a solution, usually sea water. Halite and gypsum are examples of minerals that precipitate from aqueous solutions to form chemical sedimentary rocks. Biochemical sedimentary rocks are composed of accumulations of organic debris.
