Quartz (SiO2) crystallizes from magma that is high in silica, thus most quartz is originally igneous. It then weathers out of igneous rocks as a clast and is deposited in what becomes a sedimentary rock. The original igneous rock or the quartz containing sedimentary rock can then become metamorphosed. Furthermore, quartz can also form out of solution by meteoric water or hydrothermal systems in which case it is a precipitate. It can be both crystalline or amorphous.

Where do quartz form?

Quartz typically forms in igneous, metamorphic, and sedimentary rock environments. It is commonly found in veins and pegmatites in igneous rocks, as well as in hydrothermal veins in metamorphic rocks. In sedimentary environments, quartz can be found in sandstone and shale formations.

How does quartz get into rocks?

Quartz is commonly found in many types of rocks, including igneous, metamorphic, and sedimentary rocks. It forms from the crystallization of silica-rich magma in igneous rocks, from the alteration of pre-existing minerals in metamorphic rocks, and from the cementation of grains in sedimentary rocks. Quartz can also be deposited as a vein or replacement mineral in existing rocks.
