What is the parent rock of the metamorphic rock biotite gneiss?
Biotite gneiss could have a number of protoliths (parent rocks), and those protoliths could be igneous or sedimentary; the sedimentary parent rock could be a fine-grained shale, high in biotite composition, or a granitic rock, high in biotite.
Which has a greater percentage of biotite in it rhyolite or basalt?
Rhyolite typically has a greater percentage of biotite compared to basalt. This is because rhyolite is a silica-rich volcanic rock that contains more biotite, a mica mineral, which forms in silica-rich environments. Basalt, on the other hand, is a silica-poor volcanic rock that generally contains lower amounts of biotite.
Glauconite limonite and biotite are in which sedimentary rock?
biotite is used for building appartments,houses,and hardware types of construction ok you get that.
How is Biotite formed?
Biotite is formed through a process called metamorphism, which involves the alteration of existing rocks through heat and pressure deep within the Earth's crust. It commonly occurs in igneous and metamorphic rocks, particularly in association with minerals like feldspar and quartz. Biotite typically forms under high temperatures and pressures, leading to the rearrangement of mineral grains and the crystallization of biotite within the rock.
Where is biotite most commonly found?
Biotite is most commonly found in igneous and metamorphic rocks. It can be found in granite, schist, and gneiss, among other rock types. Biotite is also often present in some sedimentary rocks, such as some sandstones.
Does the biotite rock cool quickly or slowly?
slowly

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.
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 color is the streak of biotite?
biotite has a colorless streak
Where is biotite most commonly found?

What type of rock is biotite schist?
Biotite schist is a metamorphic rock that forms from the metamorphism of mudstone or shale. It consists mainly of biotite mica mineral grains, along with quartz and other minerals. Schist has a foliated texture, meaning it has a layered or banded appearance due to the preferred orientation of minerals during metamorphism.
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.
What type of minerals are biotite and muscovite?
Generally referred to as micaceous minerals, biotite and muscovite are silicate minerals having perfect basal cleavage. They both contain most of the same elements, just in different quantities. However, biotite is soluble in sulfuric acid and has iron and magnesium in it, where muscovite does not. They can be found in all types of rock.
