Biotite: A Ferromagnesian Silicate Mineral

What is considered a ferromagnesian silicate?

Among the options provided, which mineral is considered a ferromagnesian silicate?

Final Answer

Among the options provided, biotite is considered a ferromagnesian silicate.

Ferromagnesian silicates are a group of minerals that contain both iron (Fe) and magnesium (Mg) in their chemical composition. They are characterized by their dark color and high density. Ferromagnesian silicates are commonly found in igneous and metamorphic rocks. They play a significant role in understanding the formation and composition of rocks, as well as their physical and chemical properties.

Out of the options given, biotite is considered a ferromagnesian silicate. Biotite is a dark-colored mineral that belongs to the mica group. It is commonly found in igneous and metamorphic rocks and is known for its characteristic flaky texture. Biotite contains both iron and magnesium in its chemical composition, making it a ferromagnesian silicate.
