What is basalt crystal size?
Basalt is 1mm
How does a basalt differ from gabbro?
Gabbro has much larger grains that basalt does. This is because basalt cools faster than gabbro and has less time to form 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 rock has larger crystals than basalt and granite?
A pegmatite is a rock formed under certain favorable circumstances that enhance the crystal size of the rock. The crystals would be larger than those in basalt, an extrusive igneous rock, and granite, and intrusive igneous rock.
Why is granite coarse grained while basalt is fine grained?
Basalt is fine grained because it is rapidly cooled from molten material. Rapid cooling inhibits the growth of large mineral crystals, as the time that they are allowed to form and grow is lessened.Basalt grains are small because of fast cooling.
How willl the sizen of crystals in granite b different from the size of the crystals in basalt?
The will be large in an extrusive granite and fine in an intrusive basalt.
What is the size of basalt crystals?
relativity small

Explain pegmatite is coarse grained with large crystals basalt is fine grained with small crystals and obsidian has no crystals?
Crystal size in these rock types is determined by their rate of cooling. Pegmatites have large crystals due to very slow cooling. Obsidian has microscopic crystals due to almost instantaneous cooling.
What size are the crystals in marble?
They are usually Medium size compared to those in Granite and compared to Basalt.
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.
Which has smaller crystals basalt or granite?
i think that basalt is the smaller crystals out of the two, as the crystals in granite are larger.
Does basalt have small crystals or big?
Since basalt is extrusive it cools quickly and forms small crystals.
What is the comparison of granite and basalt in terms of origin and texture which is intrusive and which is extrusive?
Basalt can't see crystals and basalt is extrusive. Granite you can see the crystals and is intrusive.
What is an igneous rock with crystals?
Granite with larger crystals, basalt with smaller crystals.
How big are basalt crystals?
small
