What are rock-forming minerals?

Rock-forming minerals are the key constituents in the formation of rocks. These minerals, which include quartz, feldspar, mica, and amphibole, among others, make up the majority of the Earth's crust. They are classified based on their chemical composition and structure. Rock-forming minerals are formed through various geological processes such as cooling and solidification of magma, precipitation from water, and metamorphism. Their abundance and properties determine the characteristics and properties of different types of rocks, making them essential for understanding the Earth's composition and geological history.
