milky quartz is either metamorphic or igneous
Quartz is actually a silicate mineral that appears in metamorphic, sedimentary, and igneous rocks.
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.
Neither. Quartzite is metamorphosed quartz sandstone, and is therefore a metamorphic rock.
Quartz is a type of clastic rock. It is widely found in igneous, metamorphic, and sedimentary rocks, and is often colored by impurities.
igneous
Quartz is a mineral found in many igneous, sedimentary, and metamorphic rocks. One metamorphic rock that is rich in quartz is quartzite. A quart is any of several archaic units of volume with values between 0.95 litre and 1.14 litre, the smallest and the largest of which are still used in the USA.
Quartz is a mineral, not a rock.
quartz is a mineral, not a rock, so it can't be igneous, sedimentary or metamorphic
Rose quartz is actually a silicate mineral that may appear in metamorphic, sedimentary, and igneous rocks.
No, diorite is a simply an igneous rock with lots of mafic minerals and quartz.
Quartz is a silicate mineral (SiO2). igneous A+
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.
Amethyst is an igneous rock. It is quartz which has been stained purple by mineral impurities.
Onyx is a variety of quartz, usually with a sedimentary origin.
Neither. Quartzite is metamorphosed quartz sandstone, and is therefore a metamorphic rock.

actually, it truly depends on the type of rock the metamorphic rock formed from. in other words, if it formed from a rock that held basalt in it, the rock has basalt in it. remember that a metamorphic rock can be formed by more than two different types of rock (such as metamorphic quartz, slate, "fool's gold", plus granite). it does not matter which class the metamorphic rock formed from (but if a m. rock such as m. quartz, there is more likely a chance of finding a trace of basalt), as long as it formed from two different class of rock (this does not always apply, for there can be a metamorphic rock made from two or more metamorphic rocks). i would get into geodes...... but that's another answer. :)
