What does porphyrytic texture indicate about the story of an igneous rock?
it tells you that the igneous rock formed in two stages,stage one occurred deep into the earth were large crystals formed from and then it eruptedas a volcano in stage two were small crystals formed
A type of instrusive igneous rock with large crystals?
Gabbro.
Igneous rocks with large crystals?
Igneous rocks with large crystals are known as intrusive or plutonic rocks. These rocks form underground as magma cools slowly, allowing large crystals to grow. Common examples include granite and diorite.
Do intrusive rocks have large crystals because they cool quickly?
No. Intrusive igneous rocks have large crystals because they cool slowly.
Are igneous rocks formed from smalll minerals?
Not necessarily. Intrusive igneous rocks, especially pegmatites, can have large crystals.
What does the presence of large crystals in an igneous rock indicate?
The presence of large crystals in an igneous rock indicates that the rock cooled slowly beneath the Earth's surface, allowing sufficient time for the crystals to grow to a larger size. This type of slow cooling typically occurs in intrusive igneous rocks, such as granite.
Do igneous rocks have small crystals large crystals or no crystals?
Igneous rocks can have both small and large crystals, depending on how quickly they cool. If an igneous rock cools slowly beneath the Earth's surface, it can form large crystals, while rapid cooling at the Earth's surface or in an eruption can result in small or no visible crystals.
What condition lead of the formation of large crystals in an igneous?
Igneous rocks will develop large crystals is they cool slowly underground.
What conditions lead to formation of large crystals in an igneous rock?
Igneous rocks will develop large crystals is they cool slowly underground.
What do the large crystals in igneous rocks tell about the rock?
That it cooled very slowly.
What does porphyrytic texture indicate about the story of an igneous rock?

What igneous rock does not have large crystals?
sedimantry
What is an extrusive igneous rock with large crystals?
granite
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 are Igneous rocks that have large crystals and small crystals?
Igneous rocks with large crystals are called intrusive rocks, formed from magma cooling slowly beneath the Earth's surface, allowing for large crystals to form. Igneous rocks with small crystals are called extrusive rocks, formed from lava cooling quickly on the Earth's surface, resulting in small crystals due to rapid cooling.
A type of instrusive igneous rock with large crystals?
Gabbro.
What is the size of crystals in an igneous rock called?
The size of crystals in an igneous rock is called texture. Texture can range from fine-grained (small crystals) to coarse-grained (large crystals).
