ABSTRACT _ The study area is situated about 11 kilometers southeast of Ywangan. Total area coverage is about 25 square kilometres. The major rock units are Chaungmagyi Group, Pindaya Group, Mibayataung Group and Plateau Limestone Group. Structurally, the faults are trending NNW-SSE and NE-SW. Lead ore mineralization occurs in the Middle Ordovician age of the Wunbye Formation. It is found at two localities. Shwe Taung lead occurrence - 1 is associated with brecciated argillaceous limestone and Shwe Taung lead occurrence - 2 is associated with the dolomitic limestone, both of Wunbye Formation. The chief ore mineral is galena and associated ore minerals are sphalerite, chalcopyrite, anglesite and pyrite. Two types of alterations; the dolomitization and silicification can be recongnized. Ore microscopic study reveals that the alignments of cleavage pits are wavy and extremely curved in galena. It indicates that there have been considerable amount of deformation during and after ore deposition. Open-space filling and replacement texture are observed in the ore microscopic study. The lead mineralization is controlled by lithology, stratigraphy and structure. Shwe Taung Lead Deposit is carbonate-hosted , stratabound and epigenetic in origin as judged by its geological characteristics. According to the report of Shwe Lar Taung Mining Co.Ltd; February, 2013, estimated tonnage of Shwe Taung Lead Occurrences 1 and 2 is 2073 tonnes. Average AAS assay results of metal contents are Pb 2.02%, Zn 0.0236%, Fe 0.4676% and Ag 85ppm or g/t. Based on the geological, mineralogical and geochemical signatures, the lead ore deposits of Shwe Taung, Htaminbaung area is carbonate-hosted, stratabound and epigenetic deposits and most probably belong to a Pb-rich sub-type of the Mississippi Valley-Type (MVT) deposits. <br/><br/>Keywords : Shwe Taung, Wunbye Formation, carbonate-hosted, stratabound, epigenetic deposits,MVT. |
