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.

What rock is composed mainly of ferromagnesian minerals?
Ultramafic rocks are made of ferromagnesian minerals.
What do ferromagnesian minerals have in common?
Ferromagnesian minerals are minerals that have iron or magnesium in their structure. The greater specific gravity is between 3.2 and 3.6. Some examples are pyroxene, biotite, garnet, and olvine.
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.
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 3 examples of ferromagnesian minerals?
Pyrite, Hematite, Augite

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.
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.
