Igneous rocks that contain many dark silicate minerals and that also are rich in magnesium and iron have a composition that is . ultramafic andesitic basaltic granitic?
Igneous rocks that contain many dark silicate minerals and are rich in magnesium and iron have a composition that is classified as ultramafic. These rocks typically contain high amounts of olivine and pyroxene, making them dense and dark in color. Examples include peridotite and komatiite, which are formed from very high-temperature magmas.
What kind of rock makes up most of the igneous rock?
Most igneous rocks are made up of silicate minerals, such as quartz, feldspar, mica, amphibole, and pyroxene. These minerals are rich in silicon and oxygen and form the bulk of the composition of igneous rocks.
What does igneous rock composition mean?
Igneous rock composition basically means how the rock would look if you were to cut it in half. In the case of igneous rock, you would see the different layers of rocks that have melted with it.
What is the silicate mineral that is found in the greatest variety of igneous rocks?
Quartz is one of the most abundant silicate minerals found in igneous rock.
Which minerals are not present in felsic type igneous rocks but are present in mafic type igneous rocks?
Mafic igneous rocks typically contain minerals like olivine, pyroxene, and amphibole which are not commonly found in felsic igneous rocks. These minerals have higher concentrations of iron and magnesium and form at higher temperatures as compared to the minerals present in felsic rocks.
Igneous rock that contains many dark silicate minerals and that also are rich in magnesium and iron have composition that is?
mafic. Mafic rocks typically have high concentrations of magnesium and iron, as well as dark silicate minerals like pyroxene and olivine. These rocks are commonly found in oceanic crust and volcanic regions.

Igneous rocks that contain many dark silicate minerals and are rich in magnesium and iron have a composition that is classified as ultramafic. These rocks typically contain high amounts of olivine and pyroxene, making them dense and dark in color. Examples include peridotite and komatiite, which are formed from very high-temperature magmas.
A certain igneous rock contains about 25 percent dark silicate minerals The remainder of the rock is mostly plagioclase feldspar What type of composition does tthis igneous rock have?
ultramafic
It is generally true that igneous rocks are composed of what type of mineral?
igneous rocks are composed of silicate minerals
What composition refers to rocks with many dark silicate minerals and plagioclase feldspar?
The composition referring to rocks with many dark silicate minerals and plagioclase feldspar is called basalt. Basalt is a fine-grained igneous rock that is commonly found in oceanic crust and volcanic islands.
What type of composition does an igneous rock have that contains mostly plagioclase feldspar and about 30 percent dark silicate minerals?
The igneous rock with mostly plagioclase feldspar and about 30 percent dark silicate minerals is likely a basalt. Basalt is a fine-grained extrusive rock that is commonly found in oceanic crust and volcanic islands. The dark silicate minerals in basalt are typically pyroxene and olivine.
Is chrysolite silicate or non silicate?
Chrysolite is a silicate mineral. It is a type of magnesium-rich olivine silicate mineral commonly found in igneous and metamorphic rocks.
What kind of rock makes up most of the igneous rock?
Most igneous rocks are made up of silicate minerals, such as quartz, feldspar, mica, amphibole, and pyroxene. These minerals are rich in silicon and oxygen and form the bulk of the composition of igneous rocks.
Definitions for basaltic composition?
a compositional group of igneous rocks indicating that the rock contains substantial dark silicate minerals and calsiumrich plagioclase feldspar. a compositional group of igneous rocks indicating that the rock contains substantial dark silicate minerals and calsiumrich plagioclase feldspar.
Ferromagnesium silicate contain what elements?
Ferromagnesium silicates, like olivine and pyroxene, contain silicon, oxygen, magnesium, and iron as the main elements. These minerals are common in Earth's mantle and in igneous rocks.
What does igneous rock composition mean?
Igneous rock composition basically means how the rock would look if you were to cut it in half. In the case of igneous rock, you would see the different layers of rocks that have melted with it.
What is the name of the coloured silicate material found in igneous rocks and coarse granites?
They are silicate minerals like feldspars, micas, and olivine.
