What two minerals are found in gneiss that contain iron and magnesium?
The two minerals commonly found in gneiss that contain iron and magnesium are biotite, a dark-colored mica mineral rich in iron and magnesium, and amphibole, a group of dark-colored mineral silicates that also contain iron and magnesium.
What is the mantle rich in?
Mafic and ultramafic minerals, high in magnesium and iron.
Which layer is composed of silicates of metallic compounds?
The mantle layer of the Earth is composed of silicates of metallic compounds. This layer lies between the Earth's core and crust and is rich in compounds like olivine and pyroxene that contain silicon and oxygen along with metallic elements like magnesium and iron.
Dark colored igneous rock rich in iron and magnesium?
Dark, mafic rock is relatively rich in iron and magnesium.
Igneous rocks that are dense and dark colored they form from magma that is rich in iron and magnesium and poor in silica?
These types of igneous rocks are commonly known as mafic rocks. They have a high density due to the presence of minerals like olivine, pyroxene, and amphibole, which are rich in iron and magnesium. Examples include basalt and gabbro.

Are dark-colored igneous rocks rich in iron and magnesium?
Dark, mafic rock is relatively rich in iron and magnesium.
What is the difference between dark and light silicate?
There are more differences between dark and light silicate than just their color. Light silicate is nonferromagnesian, while dark silicates are ferromagnesian. Light silicate is also lighter in gravity at about 2.7, and they usually contain bits of calcium, sodium, potassium and aluminum. Dark silicate usually has a heavier gravity between 3.2 and 3.6, and they are mostly comprised of magnesium and iron.

What is basalts crystal structure?
It is rich in iron and magnesium
Which mineral are almonds rich with?
Potassium, Calcium, iron, magnesium.
What material is oceanic crust rich in?
Iron and magnesium, when compared to continental crust.
Dark colored igneous rock rich in iron and magnesium?
Dark, mafic rock is relatively rich in iron and magnesium.
What is lava rich in?
Lava is rich in minerals such as silicon, oxygen, aluminum, iron, magnesium, calcium, sodium, and potassium. The specific composition can vary depending on the type of volcano and where the lava originates from.
What is the composition that contain many dark silicate minerals and that also are rich in magnesium and iron?
biotite
What mafic is like?
Mafic is a silicate mineral or rock that is rich in magnesium and iron, and is usually dark in color. It is formed from cooling volcanic lava.
