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 minerals are found in andesitic rocks?
Andesitic rocks typically contain minerals such as plagioclase feldspar, amphibole, pyroxene, and biotite. These minerals form as a result of the cooling and solidification of magma with intermediate silica content.
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 mineral does magma turn into when it cools?
Magma solidifies into a combination of minerals that are collectively called igneous rock. Minerals common in igneous rock are potassium feldspar, plagioclase feldspar, muscovite and biotite mica, quartz, hornblende, olivine, and magnetite.
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.
What describes an andesite?
Andesite are fine-grainedextrusive, igneous volcanic rock composed essentially of plagioclase feldspar and one or more mafic minerals, such as hornblende, pyroxene or biotite.(Refer to Geology.com -Igneous Rocks)

What are the chemical formula for diorite?
Diorite does not have a chemical formula. Chemical formula are for compounds. Diorite is a mixture of several compounds. The coposition of diorite is variable, so there is no chemical formula that could describe it.
What mineral does magma turn into when it cools?
Magma solidifies into a combination of minerals that are collectively called igneous rock. Minerals common in igneous rock are potassium feldspar, plagioclase feldspar, muscovite and biotite mica, quartz, hornblende, olivine, and magnetite.
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.
Is diorite a rock?
Yes, diorite is a type of rock. It is a granular igneous rock that is commonly found in mountain ranges and other geologically active areas. Diorite is composed mainly of plagioclase feldspar, biotite, hornblende, and other minerals.
What igneous rock contains mostly plagioclase feldspar and about 30 percent dark silicates?
A Diorite.
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.
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.
Which the following is a fine grained light colored extrusive igneous rock?
fine grained extrusive rocks can contain Potassium and Plagioclase Feldspar, Quartz, Biotite, Amphibole, Pyroxene and Olivine. these are all the choices for every igneous rocks
