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.
Yes, quartz can be in both igneous and sedimentary rocks. In fact, in siliciclastic (clastic) sedimentary rocks, quartz is the most abundant mineral. Chert, a microcrystalline variety of quartz, is commonly found as nodules in chemical sedimentary rocks, such as limestone.
Felsic igneous rocks, those rich in silica, may also have quartz and commonly do. These rocks include granitoids, granites, rhyolites, diorites and granodiorites, among many others.
Quartz is a mineral composed of Silicon Dioxide (SiO2).
It can therefore be formed as an igneous rock by itself (rarely) and is part of many sedimentary rocks such as sandstone. Quartz sandstone can also be metamorphosed into quartzite. Quartz can be found as part of any rock or by itself as a sediments.
Quartz is actually a mineral that can be found in all three rock types.
Quartz is a silicate mineral that can be present in any rock type.
Quartz is a mineral, not a rock. It is found in igneous, sedimentary, and metamorphic rocks.

Amethyst is actually a variety of quartz, and as a mineral, is not classified as igneous, metamorphic, or sedimentary as are rocks.
Onyx is a variety of quartz, usually with a sedimentary origin.
Rose quartz is actually a silicate mineral that may appear in metamorphic, sedimentary, and igneous rocks.

none of the above carnelian is a mineral that is a lot like quartz
milky quartz is either metamorphic or igneous
Amethyst is actually a variety of quartz, and as a mineral, is not classified as igneous, metamorphic, or sedimentary as are rocks.
Quartz is a mineral, not a rock.
quartz is a mineral, not a rock, so it can't be igneous, sedimentary or metamorphic
Onyx is a variety of quartz, usually with a sedimentary origin.
yes may be
Rose quartz is actually a silicate mineral that may appear in metamorphic, sedimentary, and igneous rocks.
Quartz is a type of clastic rock. It is widely found in igneous, metamorphic, and sedimentary rocks, and is often colored by impurities.
Neither. Quartzite is metamorphosed quartz sandstone, and is therefore a metamorphic rock.
geode, pirite (fools gold), obsidion, quartz
none of the above carnelian is a mineral that is a lot like quartz
None of them. Quartz is a mineral, not a rock type. Quartz could be found among any of the three classifications of rock--igneous, sedimentary, or metamorphic.
