Pyrite, Hematite, Augite
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.
Ultramafic rocks are made of ferromagnesian minerals.
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.

Dark (or ferromagnesian) silicates contains ions of iron (iron=ferro) and/or magnesium in their structure.
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.
Pertaining to rocks rich in dark, ferromagnesian minerals.
