It is situated between Latitude N 20 43' 00" to 20 49' 00" and Longitude E 96 47' 00" to 96 50' 14" , covering one-inch topographic map sheep 93D/13 and 93D/14. The study area, it total cover is about 21 square miles (53.76 sq. km). The structure of Bawsaing Range is highly complicated by faults i.e. overturning thrusting and normal faulting. It is a double plunging anticline, plunging south as well as north. The study area is moderately elevated, hilly terrian to flat plain region. The study area is trending north-south in direction and mainly upper Paleozonic rocks are exposed. A wide range of lithology and age ranging from Upper Cambrian to Ordovician, with local presence of clastic sediments. The mineralization is characterized by host rock alteration. There are various types of alterations near the copper ore mine of Lathar-Taung area. They are; (1) Dolomitisation, (2) Silicification, (3) Sericitisation, (4) Kaolinisation and (5) Limonitisation. Mineralization hostedin carbonate sedimentary rocks at the study area. Carbonate hosted ore consist largely of galena associated with copper, pyrite,chalcopyrite and limonite were formed the major ore minerals. Galena mineralization is strongly associated with silt-patches limestone and ooidsparite limestone by thin-section.Galena is recongnized by the presence of traingular pits, along the cleavage direction and which found secondary origin in the microscope. Analysis rock samples by AAS methods, silver content in galena is relatively high and good positive correlation (+0.382) which is epithermal deposit character. At the study area, ores are found as recrystallization, replacement and fracture filling textures. So this deposit type is stratabound deposit, fracture filling deposit (epigenetic system). Copper sulphides are found as vein type within silicified zone. Copper carbonates are formed accessary of galena ore in the study area, where show that ore mineralization result of hydrothermal activity; Includes references; CONTENTS _
