Pegmatite. Individual crystals can be as large as a bathtub. Pegmatites are the last rocks to crystallize from a solidifying body of magma. The large size of the crystals results from the slow rate of cooling and the presence of large amounts of water dissolved in the magma.

Do rocks have crystals?
Some rocks may contain crystals, but not all rocks contain crystals. Crystals can be found in rocks that have volcanic origin.
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.
Intrusive Igneous rocks are characterized by a coarse-grained texture because they contain?
Intrusive igneous rocks commonly have large mineral crystals.
Do all extrusive igneous rocks contain crystals?
No. Pure volcanic glasses contain no crystalline structure.
Rocks that have crystals?
Igneous rocks
Do rocks have crystals?

Do phaneritic igneous rocks contain viewable crystals?
By definition, yes. In contrast, aphanitic rocks do not have visible crystals.
Do extrusive igneous rocks contain crystals?
No. Pure volcanic glasses contain no crystalline structure.

Intrusive igneous rocks commonly have large mineral crystals.
Do all extrusive igneous rocks contain crystals?
No. Pure volcanic glasses contain no crystalline structure.
Do rocks that cool slowly from magma contain more crystals?
No. They would contain fewer, but larger mineral crystals when compared to igneous rocks which have cooled quickly from lava or magma.
Rocks that have crystals?
Igneous rocks
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.
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
What are Igneous rocks that have large crystals and small crystals?
Such rocks are called porphyritic.
Which type of rock typically has the largest formed crystals?
Igneous rocks usually contain the most crystals. The longer it takes the magma to cool, the larger the crystals. According to the Earth Science Reference Tables, pegmatite contains the largest crystals.
