The five most common mineral groups in rock are the silicates, carbonates, sulfates, halides, and oxides . There are about 4000 known minerals in the Earth’s crust, and about 92 % of them are silicates. The most abundant silicate is called plagioclase.
What is the largest & most common group of minerals?
Silicate Minerals
Silicates are by far the largest mineral group. Feldspar and quartz are the two most common silicate minerals. Both are extremely common rock-forming minerals.
What is the most common group of minerals?
