Is "Quartz" classified as Metamorphic, Sedimentary or Igneous rock??

Answer 1

Quartz is a mineral, not a rock.

Many sedimentary, igneous, and metamorphic rocks contain a lot of quartz, but that by itslef doesn't make quartz a rock. A variably metamorphosed sedimentary rock called orthoquartzite (depending on whose definition you use) consists of almost all quartz, and there can be some rare igneous and metamorphic rocks composed of almost all quartz.

Quartz is not a rock, and therefore it is not possible to classify it classify quartz as sedimentary, igneous, or metamorphic.

Hope that helps!

Here ya go...

"...and quartz, may be found in metamorphic rocks, but are not necessarily the result of the process of metamorphism. These minerals formed during the crystallization of igneous rocks. They are stable at high temperatures and pressures and may remain chemically unchanged during the metamorphic process. However, all minerals are stable only within certain limits, and the presence of some minerals in metamorphic rocks indicates the approximate temperatures and pressures at which they were formed."
