What is the parent rock of the metamorphic rock biotite gneiss?
Biotite gneiss typically forms from the high-grade metamorphism of sedimentary rocks such as shale or mudstone. These parent rocks undergo intense heat and pressure, causing their minerals to recrystallize and form the characteristic banding of gneiss, with biotite and other minerals aligning to create a foliated texture.
Glauconite limonite and biotite are in which sedimentary rock?
Glauconite is commonly found in glauconitic sandstone, limonite is often found in limonite sandstone, and biotite is commonly found in biotite-rich sandstone.
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.
What is the irredescent rock that peels off in layers?
They are called Micas. Some names for Micas are called, Muscovite, Biotite, and Phlogopite.
How much is a rock crystal worth?
How much is a rock crystal. Because my sisters and I had one and ill back yard when we were 12 years old but we lost it when we moved.

Does the biotite rock cool quickly or slowly?
slowly

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.
What color is the streak of biotite?
The streak of biotite is typically brown.
How much does a moon rock worth?
about 50,000 dollars

Is basalt an igneous rock and how is it use full?
basalt is an extrusive igneous rock to be specific.you can use it to extract mafic minerals such as ,Biotite(used to make insulators).But as a rock it is used in construction as building material.
Is a granite a rock or a mineral?
Granite is an igneous rock. It is commonly formed from the following minerals. Quartz, potassium and Plagioclase Feldspars and Biotite Mica.
