ASTRACT ___ <br/>Theingon area is located about 10 kilometres northeast of Ywangon Township Taunggyi District, Shan State (South), and covers approximately 20 square kilometres. It is located in the northwestern part of Pindaya Range that lies in the southwestern part of the Shan Plateau. <br/> The sedimentary rocks of the Pindaya Group (Lokepyin Formation, Wunbye Formation, Nan-on Formation) of Ordovician age, and Mibayataung Group (Linwe Formation) of Silurian age cropped out in the study area. Structurally, the Ingyi-Ingaung fault is trending nearly NW-SE. The present research work involves the carbonate rocks of the Wunbye Formation (Middle Ordovicain age ) which hosts the lead ore mineralization, and has seven microfacies, namely, oolitic -dolomitized grainstone, dolomitic limestone, dolostone, crystalline limestone, oolitic-peloidal grainstone, and peloidal-bioclastic wackestone.<br/> It is found at two localities. Peik Chinganaing Taung and Nwalabot Taung lead prospects are associated with the dolomitic limestone of Wunbye Formation. The lead sulfide mineralization is confined to the carbonate rocks of Wunbye Formation of Middle Ordovician age. Absence of igneous rocks is conspicuous. The wallrock alteration zones are narrow, with dolomitization as the main alteration, and silicification as subordinate, which happen after the ore mineralization. The one mineralogy is relatively simple where galena and barite form major constituents with minor amounts of sphalerite, pyrite, chalcopyrite, covellite and anglesite.The gangue minerals are calcite, dolomite and quartz. Both open-space fillings (veniclets, streaks,disseminations and fracture fillings) and replacement (irregular patches to massive aggregates) nature of ore mineralization are present. The lead sulphide mineralization is localized by both structural and lithostratigraphical controls. <br/> Lead values range from 0.108% to 34.22% in Peik Chinganaing Taung and Nwalabot Taung near Theingon village. The contents of zinc range from 0.004% to 0.937% copper ranges from 0% to 0.2250% and barite ranges from 0% to 30.960% .<br/> Based on the geological, geochemical and mineralogical characteristics, the lead sulphide mineralizations in the study area are carbonate-hosted, stratabound, and epigenetic in origin and may be regarded as one of the sub-type of the Mississippi Valley-Type (MVT) deposits.<br/> |
