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 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.
Rocks containing many dark silicate minerals and plagioclase feldspar have a composition.?
Rocks that contain many dark silicate minerals and plagioclase feldspar typically have a mafic composition. These rocks are rich in iron and magnesium, which contribute to their darker color. Common examples include basalt and gabbro, which are formed from the cooling of magma at varying depths. Due to their mineral content, these rocks are often denser than those with a felsic composition.
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.
An igneous rock that contains mostly plagioclase feldspar and about 30 percent dark silicate minerals has a composition that is?
An igneous rock that contains mostly plagioclase feldspar and about 30 percent dark silicate minerals is classified as a basaltic or mafic rock. This composition typically indicates a formation from a relatively high-temperature magma that is rich in iron and magnesium. The presence of plagioclase feldspar suggests a significant amount of sodium and calcium in the rock's mineral makeup. Overall, this rock type is commonly associated with volcanic activity and can be found in oceanic crust.
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

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.
