Must all rocks form crystals?
All rock does not contain mineral crystals. Obsidian, or volcanic glass, in particular is a rock that has cooled so quickly from lava that mineral crystals were not able to form.
Can large crystals be found in rocks?
Yes, rocks can contain a variety of crystal sizes.
What mineral is a mudstone?
Mustone is a clastic sedimentary rock, not a mineral.
How are igneous and metamorphic rocks alike?
Both were created under extreme heat and can contain crystals or gems.
Which foliate metamorphic rock has the smallest crystals?
Slate is a foliate metamorphic rock with the smallest crystals. It forms from the low-grade metamorphism of shale or mudstone, resulting in fine-grained crystals too small to be seen with the naked eye.
Rocks that contain crystals exhibit what texture?
Rocks that contain crystals exhibit a coarse texture. The crystals within the rock are generally large enough to be seen with the naked eye, giving the rock a grainy appearance.
Does molten rock contain large crystals?
Completely molten rock would not contain any crystals. Most magmas, however, are a mixture of molten and solid crystals of some sort. It is possible that a magma could contain larger crystals of a specific mineral.
Is mudstone igneous or sedimentary?
Mudstone is sedimentary
Does tuff have crystals?

Do all crystals contain water in crystallization?
no
Which rock has the smallest particles mudstone or conglomerate?
mudstone has smaller particles :D
Do metamorphic rocks contain lectures crystals?
yes
What are two extrusive igneous rock that contain crystals?
Basalt and rhyolite both are extrusive igneous rock that contains mineral crystals. However, the mineral crystals are normally less than 1 mm in diameter, and are therefore not discernible without magnification.
