471	Khin Hnin Swe	FACIES ANALYSIS OF PYAWBWE FORMATION EXPOSED AT PYAWBWE - MINHLAGYIN AREA, MINBU DISTRICT, MAGWAY REGION, MYANMAR	Pyawbwe � Minhlagyin area is located in Minbu Township, Magway Region. It is situated between North Latitude 19? 57' to 20? 02' and East Longitude 94? 37' to 94? 43' in one inch topographic maps of 84 L/12 and 85 I/9. The Pyawbwe Formation is characterized by thin to medium bedded, pale brown to bluish grey shale and mudstone with subordinate sandstone interbedded with buff coloured loose sand, laminated to large scaled cross-bedded, greenish grey silty clay and occasionally intercalated with hard sandstone bands. Gypsum, shell beds, lenticular and concretions are also observed. Pyawbwe Formation of the research area consists of at least 11 lithofacies and they are grouped into four lithofacies association: fan delta association, delta plain association, delta front association and prodelta association. Fan delta association is usually coarse grained resulting in higher sedimentation rate. Delta plain association may have occurred in swamp, marsh, lake and distributary channel area where are filled by overbank spilling of fine-grained material from the river during flood stages with quite energy condition. Delta front associations are present distributaries channel, subaqueous levee and distributary mouth bar. Prodelta is an environment where finer particles settle out from suspension and disperse over wide area by basinal processes. The lower part of Pyawbwe Formation is occupied by the wave and tidal influence delta front association. These include wavy laminated sandstone, laminated siltstone and clay, flaser and lenticular bedding of sandstone and shale. The middle and upper parts of Pyawbwe Formation are occupied by delta plain and prodelta. These include massive clay bearing burrow structure, shale intercalated with fossiliferous sandstone and sandstone intercalated with shale bearing gypsum.	2019

474	Tun Naing Zaw	PRELIMINARY STUDIES ON SUBSIDENCE IN BAGAN - NYAUNG OO AREA, MANDALAY REGION	Bagan - Nyaung Oo area is the most important architectural complex in Myanmar and is situated between 94�45� 00� E to 95�00� 00� E and 21�00� 00� to 21�15� 00� N. The research aim is to assess whether any subsidence is currently occurring in Bagan- Nyaung Oo area and to identify whether groundwater extraction is the main case. Subsidence is a typical geohazard for low elevated coastal areas and river basin especially when densely populated. It was only recently that the potential for hazard in Bagan � Nyaung Oo area was acknowledged, but the rates and extent of such hazard remain unknown. Bagan � Nyaunng Oo has a large urban extent and is expanding rapidly. Inhabitants and ecosystems in delta and river basin areas are becoming increasingly vulnerable to the effects of subsidence, triggered both by natural causes and anthropogenic causes. The study area covers mostly the alluvial plain beside the Ayeyarwady River and partly the debris and small fan materials derived from Tuywin Taung and Tantkyi Taung hills which are exposed with rocks of Miocene to Oligocene. Bed rocks are mainly represented by rocks of Irrawaddy Formation (Late Miocene to Pliocene), Okhmintaung Formation (Upper Oligocene) and Padaung Formation and Shwezettaw Formation (Lower Oligocene). Mainly the alluvial soils of Quaternary-Recent are deposited on the plain and along the river banks by fluvial action. The areas susceptible to landslides, rock falls, mass movements, and debris flows hazards are demarcated in the Tuywin Taung and Tant kyi Taung that have been encountered with a number of small tension cracks, active and old landslides. Side cutting in both sides of Ayeyarwady River is caused by river bank scouring and rain water resulting into steep slopes. In the rainy season, low lands adjacent to the Ayeyarwady River and the main streams in the area are affected by flood. Bagan � Nyaung Oo area is situated on the bank of Ayeyarwady River. So water-based transformation and rich agricultural soils create an environment that is suitable for rapid economic growth and urbanization along river basin area. The level of human influence throughout this rapid urbanization and excessive groundwater extraction requires detailed examination in order to prevent man-made disasters and irreparable damage being caused to the environment. Subsidence is a key contributing factor to flood risk and extreme weather events and soit needs to be better evaluated, especially in area with large exposed populations. Human-induced land subsidence is mainly caused by excessive groundwater extraction as a result of rapid urbanization or extraction of other resources. The results of land subsidence are an increased vulnerability to flooding, infrastructural failures, aquifer salinization and permanent geological deformation.	2019
475	Su Su Khing	PETROLOGY, RADIOMETRIC DATING AND ECONOMIC ASPECTS OF GRANITOID ROCKS IN NWALABO TAUNG AREA, PAUNG TOWNSHIP, MON STATE	NwalaboTaung is located 4.5 km northeast of Paung in Mon State and it lies on Yangon -Mawlamyine car road. The study area is principally composed of granitoid rocks, viz, foliated porphyritic biotite granite, porphyritic biotite granite, gneissose granite, biotite microgranite and tourmaline granite. Biotite microgranite and tourmaline granite occur as small stocks. Microgranite, pegmatite and schorl rocks are found as dykes and aplite and quartzofelspathic veins are also observed. Microdioritic xenoliths are also recognized in this area. Granitoid rocks intruded Taungnyo Formation and Martaban Beds. In this area, old local worksites of tin and tungsten are found at the place about 2.5 km north of Natkyigyaung village. Minor amounts of stibnite and pyrite occur in the northeastern part of the study area. Beside Banbwegon quarry, eastern and western Yetagon quarries near Sinywa yield huge quantity of porphyritic biotite granite for extraction of high quality dimension slabs as well as construction and road materials.	2019
476	Su Su Kyi	THE ANALYSIS OF ENGINEERING PROPERTIES OF SOILS FACILITATING THE MECHANISM OF LANDSLIDES IN HAKHA AREA, CHIN STATE, MYANMAR	The most destructive landslides had happened in Hakha on 27th July 2015and fortunately, no one faced to death in this event. However, the huge size posed a great impact on vulnerability of the town infrastructure, housings and inhabitants. In order to support the local people and regional planners, landslide investigation was carried out to produce potential landslide hazard zonation map. This paper mainly aims to present which factors play the main role in failure mechanism in this study area. Three types of landslides had been recorded in this area and the phenomena of landslides were detail investigated especially landslides in Mt. Rung and Hakha environs. The occurrence of numerous cracks on the middle and bottom potion of the landslide slope caused the critical condition for the ability to sustain this area. Therefore, to analyze this hazardous condition, the engineering properties such as physical, mechanical properties and dispersive nature of landslide materials were analyzed. From the analysis of grain size distribution and Atterberg�s limit test results, those landslide materials are low plasticity Clayey SILT (ML)by the application of unified soil classification system(USCS). The several controlling factors of landslides were noted from the field investigation and laboratory analysis in which the most crucial factor of dispersive nature to accelerate landslide when it combines with intense rainfall had been verified in this paper.	2019
477	Aye Pyae Phyo	PETROLOGICAL AND GEOCHEMICAL STUDIES OF GRANITE HOSTED W-SN DEPOSIT IN TAGU TAUNG AREA, TANINTHARYI REGION	Tagu Taung area is situated about 59 km southeast of Myeik, Tanintharyi Region. In the study area, porphyritic granite intrudes the metasediments of the Carboniferous to Early Permian Mergui Group. Porphyritic granite is medium- to coarse-grained and characterized by the phenocrysts of feldspar. It is mainly composed of quartz, plagioclase, microcline, perthite, orthoclase, muscovite, biotite, chlorite and zircon. Geochemical data indicates that the granites from the study area have A/CNK ratio (1.2-1.4) is greater than 1.1 expressing peraluminous and S-type. When plotted in the (Y+Nb) / Rb discrimination diagram, Tagu Taung granites occupy syn-COLG (syncollisional granite) setting. Therefore, it can be said that these S-type granites are formed at syncollisional setting. The W-Sn mineralization is spatially and genetically associated with porphyritic granite. W-Sn ores are associated with sulfide bearing quartz veins that intrude the graywacke and granite. There are two stages of mineralization: namely greisen stage and vein stage. Molybdenite, chalcopyrite and sphalerite were deposited during the greisenization process (early stage). Successively, wolframite, cassiterite, arsenopyrite, pyrite, chalcopyrite, bismuth and sphalerite formed in the vein stage. The Sn-W mineralization is genetically related to the S-type granite emplacement that is resulted from the partial melting of the crust.	2019
478	Min Min Aye Than	A GEOGRAPHICAL ANALYSIS ON DISTRIBUTION OF MARKETS IN SITTWAY TOWNSHIP	Theoretically, markets are located in the place where demand and supply meet together. However, other factors are differences in market, variations and transportation system and different nature of customers. This paper attempts to find out the factors that controls the development of markets in Sittway Township. Official statistics related to population, markets, etc. are collected from Township Administrative Office, Land Records Department, Meteorology and Hydrology Department, Department of Municipal and Ministry of Immigration and Population. These statistics are verified by field observation and recorded on Geographic Information Systems. Then, spatial analysis is conducted by using ArcGIS Version 9.3 software. Based on derived results, some markets are selected to conduct a questionnaire survey and to examine the controlling factors of location. Based on the analysis of derived data by using Microsoft Excel database, markets location are evaluated. The results reveal that markets are systematically (in hierarchical and functional patterns) located in Sittway Township. These patterns are controlled by accessibility, preference based on specific items, and sellers' strategy of business.	2019

There are eight major paddy varieties in the area and price slightly differs one from another. The objectives of the paper are to analyze cultivated area and production of different paddy varieties in Ngaputaw Township, to examine the rent return of paddy cultivation caused by price fluctuation and to predict future prospect of the paddy cultivation in Ngaputaw Township. To present this paper, primary data will be mainly applied and it includes price, variety, inputs, etc. Primary data will be collected through interviews, questionnaire and focus group discussion with farmers, staff of agriculture department and authorities concerned. Secondary data such as climatic data, population, paddy cultivated area and productivity will be collected from departments concerned.	2019
480	San San Khine	AN ENVIRONMENTAL APPROACH: IMPACT OF CHANNEL BANK CHANGE OF SITTAUNG RIVER IN KAWA TOWNSHIP	Severe bank erosion on the western part of Sittaung river mouth, especially the eastern part of Kawa and Thanatpin Townships of Bago Region has caused the economic and social problems since 2015. This paper is to identify the eroded eastern part of Kawa Township from 2015 until 2017. Moreover, it is to clarify the economic and social problems of the eroded eastern part of study area. Kawa is one of eight townships in Bago district that occupies the low-lying area of Sittaung and Bago rivers. The area of Kawa Township is about 1677 square kilometers (647.68 square miles) or 167667 hectares. The lost land area was during the seven years from 2010 to 2017 was about 163.16 square- kilometers (16317 hectares) which consist of waste land, le land and settlement area. The affected area due to bank collapse included 754 households and 3965 persons. Shifts in settlement area have resulted in the negative impacts on education, agriculture, animal husbandry and fishing industry and some households had to sell their cows, buffaloes and others to build their houses in the new places.	2019
