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, … Ver mais 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. Balancing the charges of the silicate anions … Ver mais Sorosilicates (from Greek σωρός sōros 'heap, mound') have isolated pyrosilicate anions Si 2O 7, consisting of double tetrahedra with a shared oxygen vertex—a silicon:oxygen ratio … Ver mais Inosilicates (from Greek ἴς is [genitive: ἰνός inos] 'fibre'), or chain silicates, have interlocking chains of silicate tetrahedra with either SiO3, 1:3 … Ver mais Tectosilicates, or "framework silicates," have a three-dimensional framework of silicate tetrahedra with SiO2 in a 1:2 ratio. This group comprises nearly 75% of the crust of the Earth. Tectosilicates, with the exception of the quartz group, are aluminosilicates. … Ver mais Nesosilicates (from Greek νῆσος nēsos 'island'), or orthosilicates, have the orthosilicate ion, which constitute isolated (insular) [SiO4] Ver mais Phyllosilicates (from Greek φύλλον phýllon 'leaf'), or sheet silicates, form parallel sheets of silicate tetrahedra with Si2O5 or a 2:5 ratio.
