Quartz is the second most abundant mineral in Earth's crust after feldspar. It occurs in nearly all acid igneous, metamorphic, and sedimentary rocks. It is an essential mineral in such silica-rich felsic rocks as granites, granodiorites, and rhyolites.

In igneous rocks and pegmatites, quartz usually occurs with potassium feldspars, muscovite, biotite and amphiboles. In sedimentary rocks or metamorphosed sedimentary rocks, quartz may be associated with potassium feldspar, calcite, dolomite or a variety of clay minerals.

A form of silica (SiO2), quartz is the second most abundant mineral in the Earth's crust. Found in various types of rocks, including metamorphic rocks (transformed under intense heat and pressure), igneous rocks (formed from solidified molten rock), and sedimentary rocks (formed by compacted and cemented sediments).
