Silicate structures. A silicate mineral ( or silicate for short) is a mineral containing silicate structures; so silicate minerals can be classified according to their silicate structures as lattice silicates, sheet silicates, chain silicates, and so forth. Note that with the exception of quartz and its polymorphs,. Rock Salt may be a synonym of the mineral Halite, but is also used referring to a rock composed of 95 to 99 percent Halite, containing impurities such as the minerals Anhydrite, Gypsum, Dolomite, Quartz, and Pyrite.
