Quartz is one of the most common and well-known minerals on the planet. Best known as the principal constituent of glass, quartz offers multiple other uses ranging from construction granulates to solar panels. It is a hard, crystalline mineral composed of silicon and oxygen atoms and the second most abundant mineral in the planet’s crust, after the feldspar family of minerals.

Quartz is a defining constituent of granite and other felsic igneous rocks. It is common in sedimentary rocks such as sandstone and shale as well as schist, gneiss, quartzite and other metamorphic rocks.
