A mineral compound containing aluminum, silicon, and oxygen that forms rocks and many common minerals like feldspar and clay.
From alumino- (aluminum) + silicate (a salt of silicic acid). The term emerged in mineralogy during the 19th century as chemists identified compounds combining these two major rock-forming elements.
Aluminosilicates make up about 50% of Earth's crust and include the feldspars found in most rocks you'll ever see—they're literally the foundation of the ground beneath your feet.
