Is an igneous rock a element?
No Igneous rock is consistently a compound - a mixture of elements. Although there are variations in composition, igneous rock is usually made up of roughly half oxygen, roughly one quarter silicon, and lesser, but significant, quantities of aluminum, calcium, sodium, potassium, and magnesium., with a sprinkling of other elements.
What are Igneous rocks that contain many dark silicate minerals and that also are rich in magnesium and iron have a composition that is?
Igneous rocks that contain many dark silicate minerals and are rich in magnesium and iron have a mafic composition. These rocks typically include basalt and gabbro, which are characterized by their higher density and darker color compared to felsic rocks. The presence of minerals such as olivine, pyroxene, and amphibole contributes to their mafic nature.
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.
Is it true or false that igneous rocks are classified by their oroigntextureshape?
False. Igneous rocks are primarily classified by their origin (intrusive or extrusive) and their mineral composition, rather than their texture or shape. Texture can be a characteristic used to further describe igneous rocks, but it is not a primary method of classification.
Is magnesium an igneous rock?
No. Magnesium is not a rock; it is a metallic element. It is present in some of the minerals found in igneous rocks. It does not occur naturally in its elemental form.

The composition of igneous rock mainly made up of magnesium and iron is called?
Basalt
Can igneous rock be felsic?
Yes. Felsic is a term used to describe the composition of some igneous 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 terms felsic and mafic used by geologists to describe?
Geologists use the terms felsic and mafic to describe the compositions of igneous rocks. Felsic rocks are rich in silicon and aluminum, making them lighter in color and less dense. Mafic rocks are richer in magnesium and iron, making them darker in color and denser.
Are basaltic igneous rocks high in iron and magnesium?
Yes, basaltic igneous rocks are typically high in iron and magnesium. This is because basalt forms from the partial melting of the Earth's mantle, which is rich in these elements. The high iron and magnesium content gives basalt its dark color and dense, fine-grained texture.
What are Igneous rocks that contain many dark silicate minerals and that also are rich in magnesium and iron have a composition that is?
Igneous rocks that contain many dark silicate minerals and are rich in magnesium and iron have a mafic composition. These rocks typically include basalt and gabbro, which are characterized by their higher density and darker color compared to felsic rocks. The presence of minerals such as olivine, pyroxene, and amphibole contributes to their mafic nature.
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.
Why are some igneous rock dark and other light?
The color of igneous rocks is determined by their mineral composition. Dark-colored igneous rocks, like basalt, contain minerals that are rich in iron and magnesium, which give them their dark appearance. Light-colored igneous rocks, like granite, tend to have higher concentrations of quartz and feldspar minerals, which are lighter in color. Overall, the mineral content and composition of the rock influence its color.
What is intermediate igneous rocks?

What is the chemical composition of the Earth's crust?
The Earth's crust is formed mainly from the elements aluminum, silicon and oxygen in the form of silicates & aluminum oxides and occurring as silicate rocks.Silicate minerals are abundant in all three rock types (igneous, metamorphic, and sedimentary) comprising the crust, but the crust is composed mainly of silicate rich igneous rock. The continental crust is composed of the lighter 'felsic' igneous rock (granitic in nature), higher in aluminum, sodium, and potassium; the oceanic crust is composed of the heavier, darker, 'mafic' igneous rock (largely basalt) which is higher in iron and magnesium than the continental crust.Crust composition: Oxygen, Silicon, Aluminum, Iron, in that order.Overall composition of the entire Earth: Iron, Oxygen, Silicon, Aluminum, in that order.Magnesium and Iron
