What is the texture of an igneous rock from magma that cools in two stages?
It's texture is porphyritic
The igneous rock texture characterized by two distinctly different crystal sizes is the texture?
Porphyritic
Is granite rock porphyritic?
Granite rock is not porphyritic. It is phaneritic because it has a coarse-grained texture.
Are sedimentary rocks that form when minerals come out of a solution classified as porphyritic?
No. I believe they are called chemical precipitate sedimentary rocks. Yes, I'm sure they're called that. Absolutely! Porphyritic is a term usually applied to igneous rocks, having to do with mineral formation and rock texture.
What is the value of a porphyritic igneous rock dated 18000 bc pfke41hotmailcom?
i dont kniw that they are worth anything!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! i dont kniw that they are worth anything!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
What are porphyritic rocks?
Porphyritic Rocks are rocks that have big and small crystal's like the Igneous Rock "Andesite".
What is the texture of an igneous rock from magma that cools in two stages?
It's texture is porphyritic
What term denotes the larger mineral grains in a porphyritic igneous rock?
Phenocrysts are the larger mineral grains in a porphyritic igneous rock. These crystals are surrounded by a finer-grained matrix known as the groundmass. The presence of phenocrysts helps in understanding the cooling history of the rock.
The igneous rock texture characterized by two distinctly different crystal sizes is the texture?
Porphyritic
What is an igneous rock with both large and small crystals?
The type of igneous rock that has large crystals surrounded by smaller crystals is not a rock but a porphyritic texture. This texture describes igneous rock that has porphyrites, or large crystals, with surrounding tiny particles, or groundmass.
Is granite an example of an igneous rock?
Yes, granite is an example of an igneous rock.
Is porphyritic rock extrusive or intrusive?
A porphyritic igneous rock is one with a texture containing large isolated crystals (phenocrysts) in a mass of fine grained crystals . 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 igneous rock is an example of batholith?
An intrusive igneous rock.
What type of igneous rock is a lava flow an example of?
It is an example of extrusive igneous rock.
Which rocks has two different size grains of the same mineral?
Pegmatite is a type of igneous rock that can have two different grain sizes of the same mineral present. This is due to the slow cooling process of the magma, allowing for the growth of large crystals (phenocrysts) within a finer-grained matrix.
Is granite rock porphyritic?
Granite rock is not porphyritic. It is phaneritic because it has a coarse-grained texture.
What is igneous material?
Igneous means that it usually comes from a volcano. For example, igneous rock is rock from a volcano
