the most abundant mineral group in earth's crust is?
silicate minerals
the largest grouping of minerals by far are the silicates; most rocks are composed of greater than 95% silicate minerals, and over 90% of the earth's crust is composed of these minerals. the two main constituents of silicates are silicon and oxygen, which are the two most abundant elements in the earth's crust. other common elements in silicate minerals correspond to other common elements in the earth's crust, such as aluminium, magnesium, iron, calcium, sodium, and potassium. some important rock-forming silicates include the feldspars, quartz, olivines, pyroxenes, amphiboles, garnets, and micas.

mineral
ferropericlase (mg,fe)o, a solid solution of periclase (mgo) and wüstite (feo), makes up about 20% of the volume of the lower mantle of the earth, which makes it the second most abundant mineral phase in that region after silicate perovskite (mg,fe)sio; it also is the major host for iron in the lower mantle. at the bottom of the transition zone of the mantle, the reaction γ-(mg,fe)[sio] ↔ (mg,fe)[sio] + (mg,fe)o transforms γ-olivine into a mixture of silicate perovskite and ferropericlase and vice versa. in the literature, this mineral phase of the lower mantle is also often called magnesiowüstite. silicate perovskite may form up to 93% of the lower mantle, and the magnesium iron form, (mg,fe)sio, is considered to be the most abundant mineral in the earth, making up 38% of its volume.
