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 is the most common silicate mineral group?
The most common silicate mineral group is the feldspar group, which includes minerals such as orthoclase, plagioclase, and microcline. Feldspars are abundant in the Earth's crust and are commonly found in igneous, metamorphic, and sedimentary rocks.
What Crustal rocks are made up primarily?
Crustal rocks are primarily made up of silicate minerals such as feldspar, quartz, and mica. These rocks include granite, basalt, and gneiss, and are commonly found in the Earth's crust.
What mineral is formed by the weathering of feldspar and other silicate minerals and is the principle mineral in clay and shale?
Kaolinite is the mineral formed by the weathering of feldspar and other silicate minerals, and it is the principal mineral in clay and shale. It is a type of clay mineral that is commonly found in sedimentary rocks.
In what form is silicon found?
Silicon is commonly found in nature as silicon dioxide (silica) in the form of quartz, as well as in various minerals such as feldspar and mica. It is also present in various silicate minerals and rocks.
What does CaSiO3 stand for?
CaSiO3 stands for calcium silicate. It is a mineral compound that is commonly found in rocks and minerals such as wollastonite.
Are silicate minerals found in Precambrian rocks?
Yes. The majority of rocks from any period of earth's history will be predominantly made of silicate minerals.
Rocks that contain dark silicate minerals and plagioclase feldspar have?
Basaltic composition, commonly found in oceanic crust and volcanic islands.

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 is the most common silicate mineral group?
The most common silicate mineral group is the feldspar group, which includes minerals such as orthoclase, plagioclase, and microcline. Feldspars are abundant in the Earth's crust and are commonly found in igneous, metamorphic, and sedimentary rocks.
Is pyroxene a mineral?
A pyroxene is any of a group of crystalline silicate mineral common in igneous and metamorphic rocks.
What Crustal rocks are made up primarily?
Crustal rocks are primarily made up of silicate minerals such as feldspar, quartz, and mica. These rocks include granite, basalt, and gneiss, and are commonly found in the Earth's crust.
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.
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.
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.
What are the soft silicate flakes found in many rocks?
The soft silicate flakes found in many rocks are likely to be mica minerals, such as muscovite or biotite. These minerals have a layered structure that allows them to break into thin flakes or sheets easily. Mica minerals are common in igneous, metamorphic, and sedimentary rocks.
What mineral is formed by the weathering of feldspar and other silicate minerals and is the principle mineral in clay and shale?
Kaolinite is the mineral formed by the weathering of feldspar and other silicate minerals, and it is the principal mineral in clay and shale. It is a type of clay mineral that is commonly found in sedimentary rocks.
