Silicate minerals are rock-forming minerals made up of silicate groups. They are the largest and most important class of minerals and make up approximately 90 percent of Earth's crust. In mineralogy, silica (silicon dioxide, SiO2) is usually considered a silicate mineral. Silica is found in nature as the mineral quartz, … See more A silicate mineral is generally an inorganic compound consisting of subunits with the formula [SiO2+n] . Although depicted as such, the description of silicates as anions is a simplification.
