Porphyritic
What else can I help you with?
The crystal the size of an igneous rock is described as its what?
texture
Is the crystal in igneous rock small if it cools quickly from magma?
yes
What Evidence Would You Look For If Attempting To Classify A Piece of igneous Rock as Extrusive?
Extrusive igneous rocks have very small crystal grains.
What relative cooling rates of igneous intrusive rocks can be estimated by comparing rocks?
Crystal
Does igneous rock texture refers to size?
please anyone else can answer this question I'm in hurry pls.
This igneous texture is characterized by two distinctively different crystal sizes?
The igneous texture characterized by two distinctively different crystal sizes is known as porphyritic texture. Porphyritic rocks have larger crystals (phenocrysts) surrounded by a fine-grained matrix (groundmass), indicating two different stages of cooling within the magma.
Is crystal an igneous rock?
yes
Why is pegmatite igneous?
Pegmatite is classified as an igneous rock because it forms from the cooling and solidification of molten material, typically within the Earth's crust. Pegmatite is characterized by its large crystal size, which indicates that it cooled slowly, allowing the minerals to grow to a significant size.
The crystal the size of an igneous rock is described as its what?
texture
What is The crystal size of an igneous rock is described as?
texture
What is the difference in crystal growth between intrusive and extrusive igneous rock?
The crystal growth of intrusive igneous is substantially more so than extrusive igneous. Magma cools quicker on the earth's surface, extrusive igneous formed, as opposed to below the crust, intrusive. Therefore the longer it takes to cool the magma, the more the crystal growth.
What is a xenocryst?
A xenocryst is a crystal which does not occur in a specific igneous rock.
Where would you find igneous rock with the smallest crystal?
at home
What is the igneous rock that cooled too quickly for a crystal structure to form?
Volcanic glass or obsidian is a quickly cooled igneous rock without a mineral crystal structure.
Where are the two types of igneous rocks made?
Intrusive igneous rocks are formed beneath the Earth's surface through the slow cooling of magma, leading to larger crystal sizes. Extrusive igneous rocks are formed at the Earth's surface through the rapid cooling of lava, resulting in smaller crystal sizes.
Is the crystal in igneous rock small if it cools quickly from magma?
yes
What is the crystal size for extrusive igneous rocks?
Fine grained
