Feldspar minerals are a group of rock-forming silicate minerals that constitute a significant portion of the Earth's crust. They are primarily composed of aluminum, silicon, and oxygen, often combined with potassium, sodium, or calcium. Feldspars are crucial in the formation of igneous, metamorphic, and sedimentary rocks and are widely used in industrial applications such as ceramics and glass manufacturing.
