== == Quartz is actually a silicate mineral that appears in metamorphic, sedimentary, and igneous rocks.
Quartz starts out as an igneous rock, but that rock can weather, it can have little pieces broken off by various processes, and those pieces can then wash away in the rain and wind up in some body of water as sediment.
Quartz is native to Igneous rock, erosion of Igneous rock produces sediment which can become Sedimentary rock. Quartz that eroded from Igneous rock becomes part of the sediment that can become Sedimentary rock.
Water can dissolve quartz out of hot Igneous rock and this quartz can recrystallize when the hot water cools while passing through nearby Sedimentary (or other) 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.

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.
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 is a rock-forming mineral--and can be found in all three rock types. There is no igneous rock formation that is exclusively composed of the mineral quartz.
