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 .?
Igneous rocks that are rich in dark silicate minerals and contain high levels of magnesium and iron are classified as mafic rocks. These rocks typically include basalt and gabbro, characterized by their darker color and denser composition. The term "mafic" is derived from the minerals magnesium and ferric iron, which are predominant in these types of rocks.
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.
What is the silicate mineral that is found in the greatest variety of igneous rocks?
Quartz is one of the most abundant silicate minerals found in igneous rock.
Which minerals are not present in felsic type igneous rocks but are present in mafic type igneous rocks?
Mafic igneous rocks typically contain minerals like olivine, pyroxene, and amphibole which are not commonly found in felsic igneous rocks. These minerals have higher concentrations of iron and magnesium and form at higher temperatures as compared to the minerals present in felsic rocks.
It is generally true that igneous rocks are composed of what type of mineral?
igneous rocks are composed of silicate minerals

What are the charicteristics of igneous rocks?
Igneous rocks are nearly always composed of silicate minerals and have an interlocking crystalline structure. The size of the crystals depends on how quickly the rock has cooled. Igneous rocks that cool near or on the surface may also contain gas bubbles.

Rocks which contain a variety of minerals are examples of a?
Igneous Rocks
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.
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.
What is the silicate mineral that is found in the greatest variety of igneous rocks?
Quartz is one of the most abundant silicate minerals found in igneous rock.
How are igneous and sedimentary alike?
Both are composed of minerals. Some sedimentary rocks contain pieces of igneous rocks.
Which minerals are not present in felsic type igneous rocks but are present in mafic type igneous rocks?
Mafic igneous rocks typically contain minerals like olivine, pyroxene, and amphibole which are not commonly found in felsic igneous rocks. These minerals have higher concentrations of iron and magnesium and form at higher temperatures as compared to the minerals present in felsic rocks.
What is the mineral composition of calcium silicate rocks?
Calcium silicate rocks primarily consist of minerals that contain calcium and silicate, such as wollastonite (CaSiO3), grossular (Ca3Al2Si3O12), and others like diopside and augite. These rocks typically form through metamorphic processes or as a result of igneous activity. The mineral composition can vary based on the specific geological environment and conditions under which the rocks were formed. Additionally, they may contain varying amounts of other elements and minerals, including carbonates and oxides.
