Silicate minerals

Rocks are aggregates of minerals. Many are silicate minerals. This granite, an igneous rock, has Quartz, an amphibole called Hornblende, a pink potassium feldspar, and a white Plagioclase feldspar. Rock-forming Minerals.

Sillimanite is an alumino-silicate mineral with the chemical formula Al2SiO5. Sillimanite is named after the American chemist Benjamin Silliman (1779–1864). It was first described in 1824 for an occurrence in Chester, Middlesex County, Connecticut, US
