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.


Why does gabbro have a higher chemical weathering rate than granite?

Gabbro is mafic intrusive igneous rock and contains olivine, pyroxene, plagioclase and amphibole. These minerals are unstable at low pressure temperature conditions. In contrast, granite is felsic intrusive igneous rock and contains high amounts of quartz and orthoclase. Stability of minerals are increasing top to bottom in Bowen's Reaction Series.


Does basalt contain minerals?

Yes, basalt contains several minerals, primarily plagioclase feldspar, pyroxene, and olivine. These minerals form during the cooling and solidification of lava, which is the defining characteristic of basalt as an igneous rock. Additionally, basalt may contain smaller amounts of other minerals such as magnetite and ilmenite, contributing to its overall composition.


What is olivine syenite?

Extremely iron-rich olivine is rare, but is present in some nepheline syenite. Other minerals common in minor amounts include sodium-rich pyroxene, biotite.


What metals contain steel?

The main element in steel is usually iron. It also contains small amounts of other substances, to improve its properties. Often it contains some carbon (not a metal), and sometimes smaller amounts of other metals.

Which intrusive igneous rock could be composed of 60 percent pyroxene 25 percent plagioclase feldspar 10 percent olivine and 5 percent amphibole?

This intrusive igneous rock could be a gabbro. Gabbros are composed mainly of pyroxene and plagioclase feldspar, with lesser amounts of olivine and amphibole. This composition suggests a mafic rock with dark minerals dominating.


What is the mineral composition of andesite?

basalt and dacite, and ranges from 57 to 63% silicon dioxide (SiO2)


What is a type of mafic phaneritic rock?

Gabbro is a type of mafic phaneritic rock. It is composed mainly of pyroxene, plagioclase feldspar, and often contains minor amounts of amphibole, olivine, or biotite. Gabbro forms from the slow crystallization of mafic magma deep within the Earth's crust.


What minerals does the rock pumice have?

There usually are no minerals in pumice. it is composed of glass.


Is gabbro intrusive or extrusive?

Gabbro is a type of intrusive igneous rock that forms beneath Earth's surface from the slow cooling of magma. It is composed mainly of pyroxene, plagioclase feldspar, and minor amounts of olivine and amphibole. Its coarse-grained texture is a result of the slow cooling process.


What is the chemical composition of a basalt?

The mineralogy of basalt is characterized by a preponderance of calcic plagioclase feldspar and pyroxene. Olivine can also be a significant constituent.


What minerals occur in granite?

Granite typically contains minerals such as feldspar (including orthoclase and plagioclase), quartz, and mica (including biotite and muscovite). Other minerals like hornblende, amphibole, and pyroxene may also be present in smaller amounts.

Dense heavy dark-colored igneous rocks form from what magma?

Dense heavy dark-colored igneous rocks form from mafic magma, which is rich in iron and magnesium and has a relatively low silica content. This type of magma tends to crystallize into minerals like pyroxene, olivine, and amphibole, resulting in rocks like basalt or gabbro.


What is the chemical composition of the asthenosphere?

The asthenosphere consists of partially-melted, ductile rock that is composed mainly of silicate minerals such as olivine and pyroxene. It also contains small amounts of water and other volatiles which contribute to its plasticity and ability to flow.
