What rock is composed mainly of ferromagnesian minerals?
Ultramafic rocks are made of ferromagnesian minerals.
What are ferromagnesian minerals?
Ferromagnesian silicates are those minerals containing ions of iron (iron=ferro) and/or magnesium in their structure. Because of there iron content, ferromagnesian silicates are dark in color and have a greater specific gravity, between 3.2 and 3.6, than nonferromagnesian silicates. The most common dark silicate minerals are olivine, the pyroxenes, the amphibloes, drk mica (biotite), and garnet.
How do ferromagnesian minerals differ from other rock forming minerals?
These minerals are usually dark in color, Ferromagnesian Minerals minerals are also denser than other rock-forming minerals.Resources: Science Impact Integrated Science Third Edition (Academe) pp.73
What are the two elements that are in all ferromagnesian minerals?
Dark (or ferromagnesian) silicates contains ions of iron (iron=ferro) and/or magnesium in their structure.
What most common mineral group is broken into the subgroups of ferromagnesian and non ferromagnesian?
The most common mineral group that is broken into the subgroups of ferromagnesian and non-ferromagnesian is the silicate mineral group. Ferromagnesian silicates contain iron and/or magnesium, while non-ferromagnesian silicates do not contain these elements. Examples of ferromagnesian silicates include olivine and pyroxene, while examples of non-ferromagnesian silicates include feldspar and quartz.
What characteristics do ferromagnesian minerals have in common?
Ferromagnesian minerals are rich in iron and magnesium, which give them dark colors like black, dark green, or brown. They are typically heavy, dense minerals with a high specific gravity. Additionally, ferromagnesian minerals often exhibit a distinct cleavage and are common in mafic igneous rocks like basalt and gabbro.

What is composed of mainly ferromagnesian minerals?
Fe (Iron) and Mg (Magnesium) that's why it's called ferromagnesian

What most common mineral group is broken into the subgroups of ferromagnesian and non ferromagnesian?
The most common mineral group that is broken into the subgroups of ferromagnesian and non-ferromagnesian is the silicate mineral group. Ferromagnesian silicates contain iron and/or magnesium, while non-ferromagnesian silicates do not contain these elements. Examples of ferromagnesian silicates include olivine and pyroxene, while examples of non-ferromagnesian silicates include feldspar and quartz.
What minerals make up 90 of the earths crust?
There are ten minerals that are so common that they make up 90% of the Earth's crust. These are quartz, orthoclase, plagioclase, muscovite, biotite, calcite, dolomite, halite, gypsum, and ferromagnesian minerals.
Where do we find mafic rocks?
Pertaining to rocks rich in dark, ferromagnesian minerals.
What is ferromagnesian rocks?
ferromagnesian rocks are dark coloured rocks with high melting point and high specific gravity. they are basic rocks that consists of the elements like iron and magnessium, and are made up of mostly the olivine and pyroxene minerals. ferromagnesian rocks are formed from the earths interior espesially within the mantle. they include gabbro, basalt and peridotite.
What is the difference ferromagnesian and non-ferromagnesian silicates?
Ferromagnesian silicates contain iron and magnesium in their composition, which gives them a dark color and high density. Non-ferromagnesian silicates do not contain iron and magnesium, resulting in lighter colors and lower densities. Ferromagnesian silicates tend to be denser and have higher melting points compared to non-ferromagnesian silicates.
