Geological Context
Quartz is an extremely common and important rock-forming mineral, crystallizing from silica-rich magmas and hydrothermal solutions in igneous and metamorphic rocks, and forming as detrital grains in sedimentary environments. Its ubiquitous presence makes it a fundamental component of the Earth's crust.
