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.
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 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.

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.
Where do we find mafic rocks?
Pertaining to rocks rich in dark, ferromagnesian minerals.

What are examples of ferromagnesian silicate?
Examples of ferromagnesian silicate minerals include olivine, pyroxenes (such as augite), amphiboles (such as hornblende), and biotite mica. These minerals contain iron and magnesium in their crystal structures, which contribute to their dark color and magnetic properties.
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.
Which ferromagnesian minerals and which of the feldspar's would be the first minerals to crystallize?
The first ferromagnesian mineral to crystallize is usually olivine, followed by pyroxene and amphibole. Among the feldspars, plagioclase feldspar is usually the first to crystallize, followed by potassium feldspar.
