milky quartz is either metamorphic or igneous
Neither. Quartzite is metamorphosed quartz sandstone, and is therefore a metamorphic rock.
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.
No, quartz is not clastic. Clastic refers to sedimentary rocks made up of broken fragments of minerals and rock material. Quartz is a mineral composed of silicon and oxygen, and it can be found in various types of rocks, including igneous, metamorphic, and some sedimentary rocks.
In this scenario, the igneous rock intrusion is the youngest rock, as it formed after the metamorphic rock was already in existence. The metamorphic rock must have been present before the igneous rock intruded into it, making the metamorphic rock the oldest of the two. Thus, the metamorphic rock is the oldest in this context.
Quartz typically forms in igneous, metamorphic, and sedimentary rock environments. It is commonly found in veins and pegmatites in igneous rocks, as well as in hydrothermal veins in metamorphic rocks. In sedimentary environments, quartz can be found in sandstone and shale formations.
Quartz is a mineral, not a rock.
Neither. Quartzite is metamorphosed quartz sandstone, and is therefore a metamorphic 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, not a rock, so it can't be igneous, sedimentary or metamorphic
No, diorite is a simply an igneous rock with lots of mafic minerals and quartz.
Quartz is a silicate mineral (SiO2). igneous A+
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. :)
== == Quartz is actually a silicate mineral that appears in metamorphic, sedimentary, and igneous rocks.
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.
Rose quartz is actually a silicate mineral that may appear in metamorphic, sedimentary, and igneous rocks.
Metamorphic rock becomes igneous rock when it is melted, then solidifies.
A metamorphic rock can become a igneous rock by melting and cooling
