2603 Aung Zaw Myint1 GENESIS OF SN-W MINERALIZATION AT MOSAKHEE, MAWCHI SN-W REGION, MYANMAR: CONSTRAINTS FROM MINERALOGY AND GEOCHEMISTRY* Tin-tungsten mineralization in the Mawchi Sn-W region, Myanmar, is predominantly confined to an Eocene granite and Carboniferous to Early Permian sedimentary and metasedimentary rocks. Apart from the other deposits of the region, stannite-kesterite is the major tin mineral of the Mosakhee, where Sn-W bearing quartz veins cut the metasediments sub-vertically. Stannite kesterite and wolframite, the major ore minerals of the Mosakhee, are associated with galena, sphalerite, hematite, raspite, cassiterite, and pyrite. The homogenization temperature (Th) of vein quartz ranges between 215 and 300 ?C, corresponding to salinities of less than 10 wt% NaCl equiv. The calculated temperature from the stannite-kesterite and sphalerite pair also coincides with the vein-filling temperatures resulting from fluid inclusion microthermometry. The ?34S values of stannite (3.6 - 4‰) and galena (4.6 - 6‰) indicate the homogeneous sulfur source. The ?34S values of galena are heavier than those of the Mawchi deposit, implying a likely different sulfur source derived from the country rocks. A brief account of oxygen isotope reveals that ?18OH2O calculation of ore fluid at 280 ?C is 2.9‰ to 4.8‰, suggesting the ore fluid is mainly composed of meteoric water. 2025
2604 Toe Naing Oo1 GEOLOGICAL PROSPECTING AND ORE MINEALIZATION OF EPITHERMAL DEPOSIT IN THE SHWEBONTHA AREA, MONYWA DISTRICT, CENTRAL MYANMAR The Shwebontha area is located about one-kilometer ENE of the Letpadaung Cu-Au deposit. This study is aimed to investigate and characterize the geological condition, rock, alteration and ore mineralization. The geology of the Shwebontha area consists of volcanic and volcaniclastic rocks of the Late Oligocene to Middle Miocene Magyigon Formation that served as the host rocks of ore mineralization. Geochemically, the volcanic rocks having calc-alkaline nature and they are classified as volcanic field (rhyolite). Three types of alteration are developed in vicinity of mineralized quartz veins including silicic, argillic, and propylitic alteration zones. Mineralization is characterized by gold-bearing silicified massive ore and chalcedonic quartz vein in rhyolite host rocks. Optical microscopy and X-ray diffractometer (XRD) analysis indicate that these veins typically contain several ore mineral assemblage such as pyrite, sphalerite, galena, chalcopyrite, gold, covellite, goethite and hematite, associated with gangue mineral characterized by quartz, calcite, chlorite/epidote and clay minerals. Based on the current available data from hydrothermal alteration, mineralization types and ore mineral assemblages from the Shwebontha area develops forming under an epithermal environment. 2025

It is mainly composed of yellow to red, fine to coarse sand, gravel, yellow to red of lateritic soil and yellowish clay. The main aquifer is Irrawaddy aquifer and Alluvial aquifer. The specific yield of the groundwater is 1000 to 2500 gallons per hour for 4 inches diameter well and the depth of the water-bearing horizon ranges from 40 ft to 350 ft in the aquifer. The concentration of hydrogen ions (pH) is between 6.5 and 7.7. Mostly, the total dissolved solids are 1900 ppm in the research area. Total salinity is low and electrical conductivity (E.C) is 160-2820 ? mho/cm. The concentration of Chloride ions is widely distributed in most of the water of the studied region and the amount present in groundwater is relatively higher than in other anions. The results of chemical data analyzed by the SSP% method, the SAR method and the MAR method show that some tube wells can be assessed as not suitable for use as irrigation water. Kurlov’s Method and PIPER method can be classified the water types, drinking water, domestic use and Irrigation water. If high amount of Iron concentration, it can be reduced of amount with aeration methods and sand filtering methods. According to the KURLOV’s Method and Piper Method, Water Types can be classified into 6 water types. According to the above methods and the WHO Drinking Water Standard, the data can assess whether the groundwater of the research area is suitable for drinking water, domestic use, and irrigation water, except that some tube wells are not suitable. 2025
2608 Aung Myo Zaw1 & Aye Ko Aung REVIEW ON THE PRE-PALEOZOIC TO EARLY MESOZOIC STRATIGRAPHY OF YE-NGAN TOWNSHIP, SOUTHERN SHAN STATE, MYANMAR The Pre-Paleozoic to Early Mesozoic rocks are well exposed in northwestern part of the southern Shan State. It is located about 13 km, NE of Ye-U, Ye-ngan Township, southern Shan State which lies in northwestern part of the Pindaya Range, located in the Eastern High Land (Shan-Tanintharyi Block). Ye ngan Township is a geologically very well-known to a great number of geologists. The present paper focused on the newly defined Pre Paleozoic to Early Mesozoic stratigraphy with two types of approach; data collection in the field and literary work in the library. The Ye-ngan Township comprises seven type sections and four reference sections of the Pre-Paleozoic to Lower Mesozoic strata such as, Chaung Magyi Group (Late Neoproterozoic), Molohein Group (late Jiangshanian to Furongian), Lokepyin Formation (Trmadocian to Floian), Wunbye Formation (Darriwilian), Nan-on Formation (Katian/ Caradocian), Tanshauk Member (Hirnantian), Linwe Formation (Silurian-Lochkovian), Zebingyi Formation (Pragian-Emsian), Maymyo Formation (Eifelian-Frasnian), Thitsipin Formation (Early to Upper Permian), and Nwabangyi Dolomite Formation (late Upper Permian-Induan to Olenikian). Most of the Paleozoic rock units are fossiliferous in Ye-ngan Township the Upper Cambrian is represented by the Molohein Group, bearing saukiid trilobites. The Lokepyin Formation which contains small brachiopods. The Wunbye Formation includes the nautiloids, brachiopods, sponge and receptaculitid algae. The Nan-on Formation is rich in fossils, among with cystoids, orthid brachiopods, bryozoans, sponges and trilobite have been recorded. The Tanshauk Member yields brachiopods and trilobites. The Linwe Formation (in the limestone) includes nautiloids, crinoids, cystoids, ostracods, conodonts; trilobites and graptolites occurred in the siliciclastic horizon. Some Devonian outcrops of the Zebingyi Formation and? Maymyo Formation are narrowly exposed in the Myogyi area where there are 2minor amounts of tentaculitids and ammonoids. There are so far no Carboniferous strata are discovered in this area. The Thisipin Formation contains rugose and tabulate corals, foraminifers mainly fusulinids, brachiopods, bryozoans, crinoids, gastropods and leaf fossils. The Nwabangyi Dolomite Formation has some fossils, ammonoids, conodonts, bivalves, and shark teeth. In completion of this works, detailed stratigraphic investigations are still needed in a matter of urgency. 2025
