What large group of rocks which form from magma of lava?
another name for the mineral crystals in cooling magma or lava
Can minerals from from the cooling of magma?
Yes. When magma cools and solidifies, mineral crystals are formed.
Can minerals form the cooling of magma?
Yes. When magma cools and solidifies, mineral crystals are formed.
Can Minerals form from the cooling of magma.?
Yes. When magma cools and solidifies, mineral crystals are formed.
What is mineral crystals of quartz biotite mica and amphibole are produced primarily by?
Cooling and soildification of magma.
Is the crystal in the igneous rock large if it cools slowly from magma?
Yes. Slow cooling magma produces larger mineral crystals.
What factor most influences the size of mineral crystals in igneous rocks?
The major factor is the amount of time the magma remains mostly liquid while cooling and solidifying. More time spent cooling produces larger crystals because of the free movement of a mineral's constituent isotopes in a somewhat liquid magma.
What determines the type of mineral formed by cooling magma?
The rate of cooling of the magma determines the type of mineral formed by the magma or lava..
What factor determine the size of crystals in metamorphic rocks?
Large mineral crystals that are all about the same size are formed from magma that cooled slowly inside the earth. Small mineral crystals (not identifiable without a microscope) formed from magma that cooled rapidly, on or near the surface of the earth.
Which type of mineral formation involves the cooling of magma?
A rich assemblage of silicate-based minerals forming the igneous rocks that are solidified from magma. The faster the cooling the finer the crystals but the minerals are the same for a specific eruption or intrusion irrespective of cooling rate.
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.
Slow cooling of hot magma lead to the formation of what crystals?
large crystals
