Yangon; University of Yangon, 2018Dissertation note: ABSTRACT_ The upper Keng Tawng project is situated on Nam Teng Chaung, about 14 miles away from southeast of Keng Tawng in Southern Shan State. Likewise, it is located at Latitude 20 44' 36" N and 98 11' 11" E and 1:63360-scale topographic map index of 93.L/2 N-935122.It is a central core, zoned embankment dam 65m high, 422m long, with dam crest at elevation 747m.
There are four different types of geological formation and group. In western part of the project area, calcitic nature of Upper Plateau Limestone is found nearby north-south trending intra-formational fault. About two-third of the mapped area is consisted of red coloured sandstone, siltstone, marl and conglomerate of Kalaw Formation in age of cretaceous. In centre of the formation, permo-carboniferous aged Plateau Limestone, triassic aged Natteik Limestone and jurassic aged Loi-An Group are exposed as inliers. The two formations, Natteik Limestone and Plateau Limestone, are cross cut by northeast trending faults interperted with aerial photo analysis of the area. The project area lies within the Kalaw Formation. Five main types of rock mass classes are identified according to CRIEPI. They are CH, CI, CM, CH and D class. The two main types of grouting which are performed at Upper Keng Tawng Dam are curtain grouting and consolidation grouting for a curtain grouting, primary hole, secondary hole and tertiary hole are drilled up to 50m. The foundation is horizontally bedded sandstone and calcareous tufa mainly, exhibiting near vertical and horizontal cracking with openings varying widely from almost tight to several inches. Most application started with 8 : 1. for a curtain grouting, primary hole, secondary hole and tertiary hole are drilled up to 60m.
A single row grout curtain was constructed by stage grouting, using split spacing method, with widely spaced primary holes then successively halving the distance between holes untill eventually the desired standard of permeability was achieved in accordance with the principles. The grout holes are spaced 3m each. The curtain line had average 5.6 Lugeon after primary holes. Average Lugeon values dropped to 4.6 after secondary holes. after tertiary holes average Lugeon values are 2.9 and after quaternary holes average lugeon values are 1.4. Addational holes are drilling and grouting to obtain target lugeon value. Most of the grout hole which are found at Upper Keng Tawng dam foundation are low to moderate take. Somewhere, actual grout take are large up to Extremely high. In conclusion, the Lugeon values at the Upper Keng Tawng dam site area are less than 2 Lugeon ag=fter the grouting. M.Sc.

Yangon ; University of Yangon, 2015Dissertation note: ABSTRACT_ Myanmar is one of the earthquake prone regins as it is located in the eastern part of Alpide Earthquake Belt and the most prominent active fault in Myanmar is Sagaing Fault. Most of the major cities in Myanmar are located along or near the major active faults and among them Taunggyi City is also included. The study area, Taunggyi City is situated in a seismically active region, it is located in Shan State (South) within the latitude 20.74 N to 20.82 N and longitude 96.95 E to 97.07 E. The population of the city is about 200,000. With regards to the previous earthquake, the well-known Maymyo Earthquake of 23 May,1912 with Magnitude (Mw 8) happened in this area and it was originated from Kyaukkyan Fault, which is passing through at about 10 km in the west of the city. Moreover, Nampon Fault is located about 38km in the east. Therefore, it can be regard is Taunggyi City as seismically active area. However, there is no researched work for seismic hazard assessment.The seismic hazard assessment is required to carry out for Taunggyi City and therefore carried out by using the deterministic way. Deterministic seismic hazard analysis is carried out for Fractile dimension of 0.5 and 0.84. As the first portion of the seismic hazard assessment, the seismic sources are identified and the controlling seismic source is determined together with necessary source parameters. Finally, the seismic hazard assessment is carried out for the estimation of ground motion such as peak ground acceleration (PGA) and spectral acceleration(SA) at the period of 0.2s and 1.0s .
In developing the seismic hazard maps, one of the main parameters is the site condition. In here the average shear wave velocity of the upper 30m, Vs30 is the important parameter to present site conditon. To determine the Vs30 for the sites represented Taunggyi City, field investigation of micrometremor survey is carried out in this study. Microtremor measurements are performed at the selected sites to estimate the average shear wave velocity of upper 30m (Vs30) and the fundamental frequency of each sites.
The DSHA map of peak ground acceleration(PGA) for fractile 0.5 is obtained as the range of 0.3g to 0.75g and PGA value of 0.66g to 1.1g for fractile 0.84. Spectral acceleration at 0.2s for the Taunggyi City range from 0.52g to 1.6g for fractile 0.5 range from 0.18g to 0.9g and for fractile 0.84, it ranges is 0.34g to 1.7g. M.Sc.

; Literary form:
Not fiction
Yangon; University of Yangon, 2018Dissertation note: ABSTRACT _ Kyauktap area, the study area is about 18 kilometers north of Heho. Kalaw Township, Taunggyi Distrinct. It covers approximately 25 square kilometres.
Regionally, the Precambrian rocks of Chaungmagyi Group are surrounded by Lower Paleozoic rocks. The study area is located in the southern part of Bawsaing Range that lies in the southwestern part of the Shan Plateau. Sedimentary rocks of the Wunbye Formation, Nan-on Formation of Pindaya Group (Ordovician age) and Linwe Formation of Mibayataung Group (Silurian age) cropped out in the study area.
According to petrographic classification, Wunbye Formation can be divided into six microfacies: Oolitic Dolomatized Grainstone, Dolomitic Limestone, Crystalline Limestone, and Ferruginous Lime Mudstsone of Linwe Formation.
The lead mineralization is confined to the carbonate rocks of Wunbye Formation of Middle Ordovician age. Absence of igneous rocks is conspicuous. Two types of wallrock alteration are dolomitization as the main alteration, and silicification as subordinate, which predate the ore mineralization. The ore mineralogy is relatively simple. The major ore minerals are galena and barite, and its associated minerals are sphalerite, pyrite, chalcopyrite, covellite and anglesite. The gangue minerals are calcite, dolomite and quartz. Both open-space fillings (veinlets, disseminations,fracture fillings and solution collapse breccias) and replacement (irregular patches to massive aggregrates) styles are the nature of ore mineralization. Lead mineralizations are localized by both structural and lithostratigraphical controls.
There are three prospects of lead mineralization in the study area. Pb values range from 3.746%to 58.34%. The content of Zn ranges from 0.0% to 16.45% Cu ranges from 0.0% to 0.024% in the study area.
Based on the geological, geochemical and mineralogical characteristics, the lead mineralizations in the study area carbonate-hosted, stratabound deposits; and epigenetic in origin and may be regarded as one of the sub-types of the Mississippi Valley-Type (MVT) deposits.

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.
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.
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.
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% .
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.

The area is covering about 32 kilometers. The Bawsaing- Heho area is characterized by the rocks of the Molohein Group (Upper Cambrian), Pindaya Group (Ordovician), Mibayataung Group (Silurian) and Plateau Limestone Group (Permocarboniferous). The research area consists mainly two rocks type of Pindaya Group (Ordovician), namely Wunbye Formation and Nan-on Formation. Most of the area is covered by the rocks of the Wunbye Formation. It covers about 95% exposure-wise.Attitude of the rocks are generally trending N-S and dipping to the East. Petrographically,Wunbye Formation can be grouped as (1) Laminated Mudstone, (2) Pelloidal Wackestone, (3) Oolitic Packstone (4) Dolostone. The six elements were analyzed by AAS. They are As, Ag, Cu,Pb, Zn and Fe. There is a good positive correlation all of the pairs. From among the pairs of elements with lead, in rock samples, silver shows a strong positive correlation (+0.873). According to the cluster analysis, Lead is strongly associated with silver and zinc. Lead mineralization in the present study area is restricted to the Ordovician rocks and specially related to the Wunbye formation. Ore minerals are ; Galena, cerrusite, sphalerite, pyrite, chalcopyrite and covellite Gangue minerals are calcite, dolomite and quartz. Disseminated galena occuring in the limestones are also parallel to the bedding. Sphalerite is usually found in association with galena and pyrite. Pyrite and chalcopyrite are occured as small irregular masses. Galena is constantly associated with barite. By the petrographic examination and field observation.alternations are dolomitization, silicification, sericitisation and pyritization. In the study area, lead sulphide mainly occur in Thaungdwin and Phayataung worksites. Lead carbonate are also excavated at the Bawphytaung hill. The veins are trending NNW, NW and EW. Most of the mine site are using square-set stoping and shafting method. The Bawsaing area is famous for its richness in lead mineralization. Nowadays, only lead and barite deposits are extracted commercially. Local villagers are also working in this mine site.

Lead mineralization of the Shwe Taung prospect, Htaminbaung area, Ywangan township, Shan State (South) / Myo Khaing. by Myo Khaing. Material type: Text; Format:
print
; Literary form:
Not fiction
Yangon; University of Yangon, 2017Dissertation note: 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.
