Six mineral belts, extending roughly north-south and being related to certain lithologic types, are recognized and delineated in the Union of Myanmar. These are: (1) Tin-tungsten belt of the Tenasserim region, southwestern Kayah State and the western marginal zone of Shan State; (2) Antimony belt of parts of Shan, Kayah and Mon states; (3) Lead-zinc-silver-barite belt of western Shan State; (4) Porphyry copper belt of Monywa and Wuntho areas' (Central Myanmar); (5) Nickel-chromium belt of northern Chin Hills; (6) Oil-gas belt of Central Myanmar, Irrawady Delta and its off-shore area (Gulf of Mataban). Of these, the antimony belt, having a sporadic distribution, is poorly defined and delineated. At least ten mineral epochs with sixteen separate or related mineral events are proposed : (1) Late Precambrian (Pb-Zn-Ag, Au); (2) Late Cambrian (Pb-Zn-Ag, Ba); (3) Late Ordovician (Pb-Zn-Ag, Ba); (4) Late Carboniferous (Sb); (5) Permo-Triassic (Fe); (6) Cretaceous, Jurassic and possibly Triassic (Sn-W); (7) Cretaceous-Eocene (Cr-Ni, jadeite, Au); (8) Mio-Pliocene (oil-gas); (9) Middle Tertiary? (gemstones); and (10) Pliocene (Mn, Cu). Also briefly discussed is the status of economic minerals of Myanmar.
