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 rock is composed mainly of ferromagnesian minerals?
Ultramafic rocks are made of ferromagnesian minerals.
What is the mantle filled with?
The Earths mantle is filled with ferromagnesian rocks with minerals such as Olivine and Pyroxene.
What is the difference ferromagnesian and non-ferromagnesian silicates?
Ferromagnesian Silicates - silicates with iron and/or magnesium in their structure. Most ferromagnesium minerals are dark-colored and more dense than the non-ferromagnesian silicates.
What most common mineral group is broken into the subgroups of ferromagnesian and non ferromagnesian?
Iron?
What are examples of ferromagnesian silicate?
augite
What rock is composed mainly of ferromagnesian minerals?
Ultramafic rocks are made of ferromagnesian minerals.
Where do we find mafic rocks?
Pertaining to rocks rich in dark, ferromagnesian minerals.
What is the mantle filled with?
The Earths mantle is filled with ferromagnesian rocks with minerals such as Olivine and Pyroxene.
What is the earth's mantle filled with?
The Earths mantle is filled with ferromagnesian rocks with minerals such as Olivine and Pyroxene.
Why are mafic rocks denser than felsic rocks?
Mafic rocks are denser than felsic rocks because they contain heavier compounds, minerals and other materials, they are ferromagnesian in composition.
What is the difference ferromagnesian and non-ferromagnesian silicates?
Ferromagnesian Silicates - silicates with iron and/or magnesium in their structure. Most ferromagnesium minerals are dark-colored and more dense than the non-ferromagnesian silicates.
What most common mineral group is broken into the subgroups of ferromagnesian and non ferromagnesian?
Iron?
What is composed of mainly ferromagnesian minerals?
Fe (Iron) and Mg (Magnesium) that's why it's called ferromagnesian
What are examples of ferromagnesian silicate?
augite
Does Light-colored rocks with lower densities form from basaltic magma?
Basaltic Magmas are dark colored, heavy and are ferromagnesian in composition, so they most times do not form light colored rocks, rather, the Felsic Granitic Magma forms the light colored rocks with lower densities.
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.
Granite igneius rocks are light colored lower density than basltic rock high silics content?
Nonferromagnesian silicates. ferromagnesian silicates on the other hand are usually high density and dark in color.
