Some rocks may contain crystals, but not all rocks contain crystals. Crystals can be found in rocks that have volcanic origin.

∙ 9y agoAll rocks do not have crystals. This is common feature of igneous rocks . The crystals are seen by slicing the rock.

∙ 10y agoYes. All rocks apart from natural glass contain crystals.
Wiki User
∙ 12y agoYes. Igneous rocks (with the exception of volcanic glass) are made entirely of mineral crystals.
Absolutely... Yes! Igneous rocks contains crystals.
Wiki User
∙ 15y agoNo. Extrusive igneous rocks like obsidian and pumice have cooled so rapidly that crystals do not have a chance to form. They are essentially natural glass.

Rocks that contain crystals exhibit what texture?
What rocks contain crystals?
Do igneous rocks have small crystals large crystals or no crystals?
It depends on the type of igneous rock. Intrusive igneous rocks such as granite have large crystals, extrusive igneous rocks may have small crystals as in basalt or no crystals as in pumice.
What are Igneous rocks that have large crystals and small crystals?
Such rocks are called porphyritic.
Rocks that have crystals?
Igneous rocks
Where would you expect to find an igneous rock with small crystals?
you would find igneous rocks with small crystals at the bottom of the volcano, this is because when the rocks crack. It brakes apart into igneous rocks

Do all intrusive igneous rocks have crystals?
Yes. All intrusive igneours rocks and many extrusive rocks have crystals.

Do igneous rocks have crystals in them?
Not all of them. Volcanic glass does not have crystals.
Are sugar crystals rocks?
No.
Do phaneritic igneous rocks contain viewable crystals?
By definition, yes. In contrast, aphanitic rocks do not have visible crystals.
What is a type of igneous rock that forms visible crystals?
Granite, gabbro, and diorite are a few igneous rocks that forms crystals. Igneous rocks that form visible crystals are intrusive igneous rocks, rocks that form under the earth's surface.
Why do some igneous rocks have big crystals or grains and some igneous rocks have small crystals or grains?
how long they stayed in the volcano; how much time the crystals had to form
Name some rocks which have crystals?
All rocks have crystals, or at least crystalline structures. Sedimentary rocks may not have crystals as such, but the individual grains have internal crystal structures. All magmatic and metamorphic rocks have crystals, though they may be too small to be seen without the aid of a microscope. Only possible exception is Obsidian (volcanic glass) which may be amorphous.
