Oxygen is present in the atmosphere in trace quantities in the form of carbon dioxide (CO2). The Earth's crustal rock is composed in large part of oxides of silicon (silica SiO2, as found in granite and quartz), aluminium (aluminium oxide Al2O3, in bauxite and corundum), iron (iron(III) oxide Fe2O3, in hematite and rust), and calcium carbonate (in limestone). The rest of the Earth's crust is also made of oxygen compounds, in particular various complex silicates (in silicate minerals). The Earth's mantle, of much larger mass than the crust, is largely composed of silicates of magnesium and iron.
