== == Quartz is actually a silicate mineral that appears in metamorphic, sedimentary, and igneous rocks.
quartz is a mineral, not a rock, so it can't be igneous, sedimentary or metamorphic
Quartz is a mineral not a rock. Fossils can be found associated with quartz in sedimentary rock not inside the quartz.
Sedimentary.
By definition. A sedimentary rock is formed from sediments, chemical, organic, or clastic. A metamorphic rock has undergone a change in mineral alignment or mineral composition due to heat and/or pressure. An igneous rock forms from solidification of magma via cooling.
Sedimentary Rocks. 75% of rocks exposed to the surface are sedimentary.
quartz is a basic mineral and can be in any type of rock

milky quartz is either metamorphic or igneous
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.
Quartz can be found in igneous rocks when it crystallizes from molten magma during the cooling and solidification process. In sedimentary rocks, quartz can be present as a result of weathering and erosion of pre-existing rocks, with the quartz grains being deposited and compacted over time to form sedimentary rocks like sandstone.
Quartz can be present in igneous rocks if it crystallizes from magma during the cooling process. In sedimentary rocks, quartz can be derived from the weathering and erosion of pre-existing rocks rich in quartz, transported and deposited as sediment, and then cemented together to form the sedimentary rock.
Amethyst is a type of mineral from the quartz family, not a rock. Quartz is formed in igneous, metamorphic, and sedimentary environments, but amethyst specifically is often found in metamorphic rocks.
Quartz is a mineral primarily made up of silicon and oxygen. It is the second most abundant mineral in the Earth's continental crust and is commonly found in igneous, metamorphic, and sedimentary rocks.
