_aABSTRACT _ The study area is located about 8 km north to Mong Yawng Township, Shan State (East). It is bounded by latitude 21° 09' 40" N to 21° 15' 00" N and longitude 100° 19' 55" E to 100° 25' 05" E and area coverage is approximately 50 square kilometers and 0.21 square kilometer for detail geological map. The study area lies in apart of Eastern Highlands area of Myanmar. In addition , it is also a part of Eastern Granitoid Belts of Myanmar. The study area is mainly composed of Molohein Group of Cambrian in age and granite and vocanic rocks of late Triassic in age. Iron mineralization is found in reddish brown colored silstone and yellowish grey in colour mudstone of Molohein Group. The mineralization occurs mainly as massive, replacement and fracture fillings. Mineralization is found within the fracture zone and it is related with east-west trending lineaments systems, which are discordant to north-south direction regional structure. According to chemical assay result iron (Fe) is 60.33% - 65.61% copper(Cu) is 21 ppm-36 ppm, lead (Pb) is 59 ppm - 141 ppm and zinc (Zn) is 13 ppm-121 ppm.Ore minerals are magnetite, hematite with minor amount of pyrite. Gangue mineral is quartz. In study area, four types of alterations ard found such as silicification, sericitization,kaolanization and pyritization. The possible age of mineralization may be late Triassic in age. Geochemically, collected 30 soil samples, 19 ore samples from mineralized zone and analyzed by AAS for Fe, Au, Ag, Cu, Pb, Zn and XRF for Mgo, SiO2, CaO, TiO2 ,Cr2O3, MnO, Fe2O3, NiO and CnO. According to the field study and microscopic study, the iron mineralization is considered as igneous related hydrothermal iron deposit because of bladed quartz in mineralization, bercciated quartz, silicified zone are found close to ore mineralization zone.
