it depends on the heat, if it cool very quick then it has small crystals but if it cool very slowly than it is bigger the slower the cooling period the bigger the crystals

What conditions lead to the formation of large crystals in an igneous rock?
Igneous rocks will develop large crystals is they cool slowly underground.
Igneous rocks with large crystals?
quartz
A type of instrusive igneous rock with large crystals?
Gabbro.
What are large mineral crystals commonly found in?
large mineral crystals are most likely found or have grown in igneous or metamorphic rocks
Do intrusive rocks have large crystals because they cool quickly?
No. Intrusive igneous rocks have large crystals because they cool slowly.
What determines how large the crystals in an igneous rock will be?
How fast the magma or lava cooled. How fast the rock cooled
What determines how large the crystals in the igneous rock will be?
How fast the magma or lava cooled. How fast the rock cooled
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 igneous rock does not have large crystals?
sedimantry
What are Igneous rocks that have large crystals and small crystals?
Such rocks are called porphyritic.
Igneous rocks with large crystals?
quartz
What is an extrusive igneous rock with large crystals?
granite
What determines the size of the crystals that form in a sample of granite?
Crystal size in igneous rock is predominately a factor of time spent in cooling from lava or magma. Samples with relatively large crystals are the result of the magma having spent a longer amount of time at ideal crystal forming temperatures for each mineral present.
A rock with large crystals surrounded by small crystals called?
It's an igneous porphyry.
