Among them, Pyawbwe and Kyaukkok formations were studied to predict the geochemical characteristics of the study area. To conduct XRF analysis, six sandstone samples were taken from the selected layer of sandstone in the Pyawbwe Formation and six sandstones were taken from the selected sandstone layers in the Kyaukkok Formation. According to the chemical classification of sandstone diagram, the sandstones of Pyawbwe and Kyaukkok f m f ‘L ’. Keywords: River, Rocks, Pyawbwe, Kyaukkok, Sandstones, Litharenite. I. INTRODUCTION II. TOPOGRAPHY The study area, Chauk Oil Field, is situated on the eastern Topographically, the study area can roughly be said as bank of the rolling terrain topography and a range of small hills is running NNW-SSE direction in the eastern part. The highest m f point of the study area located at the northeastern margin is ʹ ʺ ʹ ʺ ʹ ʺ about 180m above sea level. The western part of the area is ʹ ʺ -13 UTM Map (Fig 1). bounded by the Ayeyarwaddy River flowing from NNE to SSW.
