What chemical can be found in the mantle?
The mantle of the Earth contains various chemicals, with the most abundant being silicate minerals like olivine and pyroxene. These minerals are rich in elements like silicon, magnesium, and iron, which make up the majority of the mantle's composition.
How are carbonate mineral different from silicate minerals?
Carbonate minerals contain carbon and oxygen in the form of the carbonate ion (CO3-), whereas silicate minerals contain silicon and oxygen in the form of various ions containing silicon and oxygen.
Is chrysolite a silicate?
Yes, chrysolite is a silicate mineral. It belongs to the olivine group of minerals, which are composed of silicate ions containing magnesium and iron. Chrysolite is also known as peridot, a gemstone with a distinctive green color.
Is graphite a silicate?
No a silicate is a compound containing silicon and oxygen. Graphite is pure carbon.
Is quartz a ferromagnesian silicate?
No, quartz is not a ferromagnesian silicate. Ferromagnesian silicates are silicate minerals containing iron and/or magnesium along with silicon and oxygen. Quartz is a silicate mineral composed of silicon and oxygen.
What is the composition that contain many dark silicate minerals and that also are rich in magnesium and iron?
biotite
How would the color and density of rock composed mostly of non-ferro magnesium silicate minerals differ from one made up mostly of ferro-magnesium silicate?
non-ferro magnesium silicate dominated rock would be lighter in color and less dense than ferro-magnesium silicate dominated rock. NOTE: The color of olive-green belong to the ferro-magnesium silicate dominated rock group.
What is the grouping of silicate and non-silicate minerals based on?
The grouping of silicate and non-silicate minerals is based on whether they contain silicon and oxygen. Silicate minerals are divided into smaller groups based on their structure. Non-silicate minerals are didvided into smaller groups based on their composition.
What are femic minerals?
Ferro-magnesian silicate minerals ie containing iron and magnesium
What type of composition does an igneuous rock have that contains mostly plagiclase feldspar and about 30 percent dark silicate minerals?
it is ultra mafic
Do all silicate minerals contain iron?
silicon, oxygen, iron and magnesium
What are the chemical compositions of the mantle?
The Earth's mantle primarily consists of silicate minerals rich in magnesium and iron, such as olivine, pyroxene, and garnet. Its chemical composition is dominated by compounds like magnesium silicate (Mg2SiO4) and iron silicate (Fe2SiO4), alongside other elements such as aluminum, calcium, and sodium. The mantle's overall composition reflects a gradient of increasing density and temperature with depth, impacting its physical properties and behavior.
Most silicate minerals form from?
Most silicate minerals form from the crystallization of magma or lava as it cools, allowing silicate ions (SiO₄) to combine with metal cations like aluminum, iron, magnesium, and calcium. They can also form through processes such as metamorphism, where existing rocks are subjected to heat and pressure, or through weathering, where silicate minerals break down and recombine in sedimentary environments. Silicate minerals are the most abundant group of minerals in the Earth's crust, primarily due to the prevalence of silicon and oxygen in the Earth's composition.
Is the mantle is composed mainly of metallic iron with small amounts of magnesium silicate minerals?
No, the mantle is composed primarily of solid silicate minerals rich in magnesium and iron, with smaller amounts of other elements like aluminum, calcium, and sodium. The metallic component is mainly found in the Earth's core, while the mantle is predominantly rocky in composition.
The building blocks of the silicate minerals is what?
The silicon-oxygen tetrahedron is the building block of silicate minerals. The word "silicate" means the compound contains silicon in some form.
The most common mineral group contains what kind of minerals?
The most common mineral group is the silicate mineral group, which is characterized by minerals containing silicon and oxygen, often combined with other elements such as aluminum, iron, calcium, or magnesium. Examples of silicate minerals include quartz, feldspar, and mica.
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.
