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.


What is the ore of mica?

The ore of mica is called "muscovite." It is a type of mica mineral that is commonly found in metamorphic and igneous rocks. Muscovite is known for its pearlescent luster and excellent cleavage properties.


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.
