Are agates metamorphic igneous or sedimentary?
Agates are none of the above rock types, but a form of the mineral quartz, normally formed as a gas vesicle filler in igneous rocks, the microcrystalline quartz gradually filling the cavity with successive layers.
Is quartz 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.
What is the most abundant mineral in detrital sedimentary rocks?
quartz
What minerals are most common in detrital sedimentary rocks?
The most common minerals in detrital sedimentary rocks are quartz grains and clay.
Where is quartz found in the world?
White quartz, often quite massive is found in schists. Clear quartz crystals I have found in sedimentary rocks.

How do you account for the abundance of quartz?
The mineral quartz is abundant in sedimentary rocks because quartz is very durable and resistant to chemical weathering.

What types of minerals are clastic sedimentary rocks made of?
Clastic sedimentary rocks are made of broken pieces of preexisting rock that are compacted together. The mineral quartz makes up sixty percent of the clastic sedimentary rocks.
Is amethyst igneous metamorphic or sedimentary?
Amethyst is actually a variety of quartz, and as a mineral, is not classified as igneous, metamorphic, or sedimentary as are rocks.
