Abstract
The rock-forming minerals which are abundant at the Earth's surface are chiefly translucent silicates and carbonates. Opaque minerals occur as minor components in many rocks and the ore minerals, raw materials for the world supplies of metals, are mostly opaque phases. The major categories of opaque minerals are: (i) native metals, semimetals and alloys; (ii) metal sulphides and other chalcogenides (compounds of metals with Se, Te, As, Sb, Bi); (iii) oxides of certain elements, notably the transition metals: (iv) certain hydroxides and oxysalts.
