What else can I help you with?
Is biotite granite extrusive or intrusive?
Biotite granite is an intrusive igneous rock. It forms from the slow crystallization of magma deep within the Earth's crust, resulting in a coarse-grained texture.
What contains moderate amount of biotite and amphibole and proxene?
A rock containing a moderate amount of biotite, amphibole, and pyroxene could be a diorite. Diorite is an intermediate intrusive igneous rock with a composition between that of granite and gabbro, which typically contains these minerals in varying amounts.
What is the intrusive pink rock with mica?
The intrusive pink rock with mica is likely to be granite. Granite is an igneous rock that forms from the slow cooling of magma deep underground. The pink color is often due to the presence of potassium feldspar, and mica minerals, such as biotite or muscovite, can be found in granite as well.
What color is the streak of biotite?
biotite has a colorless streak
Is biotite magnetic?
no,biotite is not attracted to magetic forces (its not attracted to magnet)
Is biotite granite extrusive or intrusive?
Biotite granite is an intrusive igneous rock. It forms from the slow crystallization of magma deep within the Earth's crust, resulting in a coarse-grained texture.
Is a gabbro a intrusive rock or a extrusive rock?
it is an intrusive igneous rock with composition equivalent of basalt.it is dark colored due to high concentration of dark minerals;olivine,biotite,hornblende.
Is diorite intrusive or extrusive?
Diorite is an intrusive igneous rock, formed from the cooling and solidification of magma beneath the Earth's surface. It contains a mix of minerals such as plagioclase feldspar, biotite, hornblende, and pyroxene.
What contains moderate amount of biotite and amphibole and proxene?
A rock containing a moderate amount of biotite, amphibole, and pyroxene could be a diorite. Diorite is an intermediate intrusive igneous rock with a composition between that of granite and gabbro, which typically contains these minerals in varying amounts.
What is the intrusive pink rock with mica?
The intrusive pink rock with mica is likely to be granite. Granite is an igneous rock that forms from the slow cooling of magma deep underground. The pink color is often due to the presence of potassium feldspar, and mica minerals, such as biotite or muscovite, can be found in granite as well.
What is granodiorite?
Granodiorite is an intrusive igneous rock. Its composition is similar to that of granite but it contains more plagioclase than potassium feldspar. Biotite and hornblende are also abundant minerals in granodiorite.
What color is the streak of biotite?
biotite has a colorless streak
What is the origin of Diorite?
Diorite is a type of intrusive igneous rock that forms when molten magma cools and solidifies beneath the Earth's surface. It is primarily composed of plagioclase feldspar, biotite, and hornblende minerals. Diorite is commonly found in continental crust and is associated with processes like magma crystallization and mountain-building events.
Is biotite magnetic?
no,biotite is not attracted to magetic forces (its not attracted to magnet)
What is diorite?
Diorite is an intrusive igneous rock mostly composed of plagioclase feldspar, biotite mica, hornblende, and/or pyroxene. It mostly appears as gray in color, or whitish with black specs--a salt and pepper look. It may contain small amounts of quartz.
Which intrusive rock has the sale composition as andesite?
The intrusive rock that has the same composition as andesite is diorite. Both rocks are composed primarily of plagioclase feldspar, along with varying amounts of other minerals such as biotite, hornblende, and quartz. While andesite is an extrusive rock formed from volcanic activity, diorite forms through the slow crystallization of magma beneath the Earth's surface.
What is granodiorite made of?
Granodiorite is a phaneritic, intrusive igneous rock composed primarily of plagioclase feldspar, quartz, and one or more mafic minerals such as biotite or hornblende. It has a composition intermediate between granite and diorite.
