What is the name of a igneous rock with large crystals?

The type of igneous rock that has large crystals surrounded by smaller crystals is not a rock but a porphyritic texture. This texture describes igneous rock that has porphyrites, or large crystals, with surrounding tiny particles, or groundmass.

It is an intrusive rock.

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.

granite

Igneous rocks will develop large crystals is they cool slowly underground.

Granite have large crystals because it is an igneous rock and has cooled slowly.

Granite is an intrusive igneous rock that cooled slowly from magma and has large visible crystals.

Well The Igneous Rock: When it Forms Underground the Pressure combines with Large crystals :)

It's an igneous porphyry.

That it cooled very slowly.

Granite and gabbro are intrusive igneous rocks.

it depends on how quickly the rock cooled if it cooled quick there will have small crystals if it cooled slowly it will have large crystals

Large crystals are diagnostic of an intrusive igneous rock, as large crystals form as the source magma cools slowly.

No, melted rock that cools quickly result in igneous rock with large minerals because large crystals take time to form and the rocks that usually have them are the ones that were formed inside the earth.

Granite is coarse grained, with large crystals and its an intrusive igneous rock While Rhyolite is fine grained, with tiny crystals and is an extrusive igneous rock.

If igneous, it is called a porphyry.

An intrusive igneous rock has larger crystals than an extrusive igneous rock because it has had a longer period of time to solidify underground.

Intrusive igneous rock has visible crystals due to the increased time spent in cooling from magma.

If the magma cools slowly large crystals form and if the magma cools quickly then small crystals form

it is an igneous rock. the type of igneous rock depends on how fastly it cooled. intrusive igneous cooled slowly and has large crystals, with coarse grains. extrusive igneous rocks cooled fast have moderalty no crystals and are very fine grained

Two types of igneous rock are intrusive (also called plutonic) and extrusive. There is also porphyry rock which is partly intrusive and partly extrusive. Porphyry rock has large crystals embedded in a mass of much smaller crystals. The large crystals formed underground as does intrusive rock, and were carried in lava when it erupted. The mass of smaller crystals formed around the large crystals when the lava cooled quickly above ground, as does extrusive rock.

How fast the magma or lava cooled. How fast the rock cooled

Extrusive igneous rock consists of mineral crystals that are not observable with the naked eye. Obsidian is an extrusive igneous rock (volcanic glass) where there technically are no mineral crystals.

an igneous rock has interlocking crystals

Intrusive rock normally has visible crystals. Extrusive igneous rock has small crystals. A black extrusive igneous rock with small crystals could be basalt.
