Sources and Classification. Crushed stone is produced from all three groups of rocks on the earth's surface—igneous, sedimentary, and metamorphic. It has been estimated that the lithosphere, the solid portion of the earth's crust, is composed of: igneous rocks, 95 pct; shale, 4 pct; sandstone, 0.75 pct; limestone, 0.25 pct.
