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.
What kind of rock is feldspar?
Feldspar is a type of mineral found in igneous, metamorphic, and sedimentary rocks. It is one of the most abundant minerals in the Earth's crust and comes in different varieties such as orthoclase, albite, and plagioclase. Feldspar is commonly used in the production of ceramics and glass.
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.
When An igneous rock that contains mostly plugholes feldspar and about W percent dark silicates minerals has a composition that is?
Igneous rocks containing mostly plagioclase feldspar and a significant percentage of dark silicate minerals are typically classified as basaltic rocks. These rocks have a composition that is intermediate between mafic and felsic rocks, with a silica content of around 50-60%. Basaltic rocks often form from the solidification of magma with a basaltic composition.
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.
Rocks that contain dark silicate minerals and plagioclase feldspar have?
Basaltic composition, commonly found in oceanic crust and volcanic islands.

What type of rock is a plagioclase?
Plagioclase is not actually a rock, but a member of the feldspar family of minerals, and a major rock forming silicate mineral.
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

What minerals is a silicate Gematite Feldspar Calcite Halite?
Feldspar
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 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 are the kinds of silicate minerals?
Quartz, Feldspar, Muscovite, Biotite are among most common silicate minerals.
What is different silicate minerals produceed from solidifying magma is directly related to?
The temperature, pressure, and chemical composition of the magma are the main factors that determine the specific silicate minerals that form during solidification. Silicate minerals can vary in their chemical composition and crystal structure based on these conditions, leading to the formation of different minerals such as quartz, feldspar, mica, and pyroxene.
