Mica is a mineral that can be found in both extrusive and plutonic igneous rocks. It is commonly associated with granite, a plutonic rock, where it forms as a result of slow cooling of magma. However, it can also occur in volcanic rocks, which are extrusive, where it crystallizes from lava that cools quickly. Thus, mica itself is not categorized as exclusively extrusive or plutonic; rather, it can be present in both types of igneous rocks.
What else can I help you with?
Is mica extrusive?
No. A mineral is not inherently extrusive or intrusive. Mica can be found in intrisive igneous rocks and in metamorphic rocks.
Is granite plutonic or volcanic?
Granite is a plutonic rock, meaning it forms from the slow cooling and crystallization of magma underground. It is composed mainly of quartz, feldspar, and mica minerals.
Is dunite intrusive or extrusive?
Dunite is an intrusive igneous rock that forms from the cooling and solidification of magma beneath the Earth's surface. It is primarily composed of olivine mineral and is typically found in plutonic environments.
What is a light colored plutonic rock?
Granite is a light-colored plutonic rock that is commonly found in the Earth's crust. It is composed mainly of quartz, feldspar, and mica minerals and forms deep within the Earth's crust through the slow cooling and solidification of magma.
How do you classify rocks were they form?
those formed deep into the earth are called Intrusive or Plutonic rocks,those formed ator near thesurface are called Extrusive or volcanic rocks
Is Plutonic intrusive or extrusive?
Intrusive
Is plutonic intrusive extrusive?
Intrusive
Is mica extrusive?
No. A mineral is not inherently extrusive or intrusive. Mica can be found in intrisive igneous rocks and in metamorphic rocks.
Plutonic is also referred to as intrusive or extrusive?
Intrusive, or forming under the surface.
Is granite plutonic or volcanic?
Granite is a plutonic rock, meaning it forms from the slow cooling and crystallization of magma underground. It is composed mainly of quartz, feldspar, and mica minerals.
Are intrusive rocks volcanic?
No. Volcanic rocks are extrusive. Intrusive rocks are sometimes called plutonic.
What igneous rock is at the earths surface that is weathered and wears away?
Extrusive (volcanic) and exposed plutonic igneous rock.
Is dunite intrusive or extrusive?
Dunite is an intrusive igneous rock that forms from the cooling and solidification of magma beneath the Earth's surface. It is primarily composed of olivine mineral and is typically found in plutonic environments.
What is a light colored plutonic rock?
Granite is a light-colored plutonic rock that is commonly found in the Earth's crust. It is composed mainly of quartz, feldspar, and mica minerals and forms deep within the Earth's crust through the slow cooling and solidification of magma.
Some igneous rocks cool at the surface and some cool underground. What are the names of these two types?
Underground = intrusive/plutonic aboveground = extrusive/volcanic
How are intrusive classified?
Intrusive features are typically classified as plutonic rocks, especially inside of a volcano. Comparatively, extrusive features are also classified as volcanic rocks.
How do you classify rocks were they form?
those formed deep into the earth are called Intrusive or Plutonic rocks,those formed ator near thesurface are called Extrusive or volcanic rocks
