Earth's crust contains a lot of oxygen, which combines with many other elements. Oxides are minerals that contain one or two metal elements combined with oxygen. Oxides are different from silicates because oxides do not contain silicon.hosphates have a tetrahedron building block that is similar to that of the silicates.
