What is an example of an intrusive igneous rock with large crystals?

Porphyrite of any composition, granite, gabbro, diorite. Most intrusive igneous rocks have crystals large enough to see with the naked eye. Another term used to define an igneous rock with large crystals is coarse-grained.

What kind of igneous rock texture results from slow cooling magma?
A coarse grained texture, referred to as a phaneritic texture, will be the resultant igneous rock texture. The slower the magma cools the more time minerals have to crystallize and thus grow bigger.
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.
What stone can you see through?
A very large number if the rock forming minerals allow the transmission of light if sliced thinly enough. Some others are translucent at larger scale for example quartz and calcite. However in most rocks the size of the clasts or crystals is too small or the presence of gas inclusions or other elements causes them to become coloured, cloudy or otherwise opaque. It is possible that it may be possible to see through a pegmatite (pegmatites are a rare type of very coarsely crystalline intrusive igneous rock) if the crystals are large enough. As such in the vast majority of cases naturally occurring rocks are opaque and can not be seen through.
What is the difference between batholith and stock?
Batholiths are a massive site of plutonic rock material, such as felsic and intermediary rocks, which is created from cooled magma far within the crust of Earth. The igneous intrusions in batholiths that are around 40 sq. mi. are called stocks.
Rock deposited by water melted from a glacier?
Igneous Rock molten rock igneous rock is when it cools.
Are large crystals intrusive or extrusive igneous rock?
Intrusive
Do intrusive rocks have large crystals because they cool quickly?
No. Intrusive igneous rocks have large crystals because they cool slowly.
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.
How can you tell if a intrusive rock forms?
Large crystals are diagnostic of an intrusive igneous rock, as large crystals form as the source magma cools slowly.
What is igneous rock formed in the Earth's crust?
Igneous rock formed in the earths crust is known as intrusive rock. The magma that forms it cools slowly and therefore, creates rock with large crystals. An example of an intrusive igneous rock is granite.
Intrusive Igneous rocks are characterized by a coarse-grained texture because they contain?
Intrusive igneous rocks commonly have large mineral crystals.
What igneous rock is formed in the earth?
Igneous rock formed in the earths crust is known as intrusive rock. The magma that forms it cools slowly and therefore, creates rock with large crystals. An example of an intrusive igneous rock is granite.
Do you think extrusive or intrusive igneous rocks are likely to have larger crystals?
If a rock has large crystals, it is an intrusive rock. Intrusive rocks form underneath the Earth's surface. Magma cools slowly so it has time to form large crystals. An example is granite, where you can see the crystals with your naked eye. Rocks that have small crystals are extrusive rocks. Extrusive rocks are ones that form from lava (blasted out of a volcano) so they cool very quickly, not allowing large crystals to form. An example is obsidian, where you cannot visibly see the small crystals; it just looks like one black, glassy rock.
An igneous rock containing large crystals is most likely a?
intrusive rock
What kind of igneous rock usually contain large crystals?
Intrusive or granite.
Are igneous rocks formed from smalll minerals?
Not necessarily. Intrusive igneous rocks, especially pegmatites, can have large crystals.
What type of rock has glass like large crystals?
Intrusive igneous rocks, (Plutonic rocks)
