However, quartz is a very common mineral found in many different types of rocks, including:

* Igneous rocks: Quartz is found in granite, rhyolite, and other felsic rocks.

* Sedimentary rocks: Quartz is found in sandstone, quartzite, and conglomerate.

* Metamorphic rocks: Quartz is found in gneiss, schist, and marble.
