Magma cooling in 2 stages slow and then fast what is the resulting texture?

The resultant rock would have a porphyritic texture; large crystals (usually feldspars) scattered among small crystal grains.

What factors can effect the texture of a igneous rock?
The texture is determined by the rate it takes the molten to cool to form the rock.
What factors can affect the texture of an igneous rock?
The length of time the magma had to cool
How does the rate of cooling affect the type of igneous rock formed?
The rate at which the rock cool from the liquid magma determines their texture
Is granite formed from rapidly cooling magma?
No."Granite is formed by the slow cooling & crystallization of magma at some depth in the earth's crust, as indicated by its characteristic phaneritic & phaneritic-porphyritic texture."-The Audubon Society Field Guide to North American Rocks & Minerals
How is the size of mineral crystals in igneous rock related to the rate at which they cool?
When igneous rocks cool quickly, they have small crystals and have a texture that may be described as aphanitic. When igneous rocks cool slowly, they have much larger crystals and have a texture that may be described as phaneritic or pegmatitic.
What texture does magma in two cooling stages first slowly then quickly?
very coarse
What is the texture of cooling magma?
smooth
How Do Glassy Texture Igneous Rocks Form?
They form from the extremely rapid cooling of lava or magma. The quick cooling does not allow time for the crystallization of minerals, resulting in the formation of a natural glass.
What is the texture of an igneous rock from magma that cools in two stages?
It's texture is porphyritic
What is the type of crystal grain that forms when molten rock cools quickly?
Small crystal grains form from rapid cooling of magma resulting in an aphanitic rock texture.
What factors can effect the texture of a igneous rock?
The texture is determined by the rate it takes the molten to cool to form the rock.
What kind of texture is slow cooling of magma far beneath earth's surface?
Slow cooling of magma far beneath earth's surface has a phaneritic texture (this means that the individual crystals are large enough to be seen with the naked eye).
How is the texture of an igneous rock related to the rate which it cooled?
Quick cooling of magma results in small crystal formation. Slow cooling magma results in larger crystals.
What factors can affect the texture of an igneous rock?
The length of time the magma had to cool
What affects the grain size of igneous rock?
Porphyritic texture indicates that a magma has gone through a two stage cooling process. The magma has cooled sufficiently underground to allow some minerals to crystallize and grow in size; the magma is then expelled above ground where the remaining liquid magma solidifies quickly, allowing only small crystals to develop.
What is slow cooling magma far beneath earth's surface?
The slow cooling of magma far beneath earth's surface creates the rock inside earth to change slowly... this means that earths surface changes in times because of this cooling magma.
How do igneous rocks with glassy textures form and where?
They form from the extremely rapid cooling of lava or magma. The quick cooling does not allow time for the crystallization of minerals, resulting in the formation of a natural glass.
