"Sedimentary Facies Analysis of Irrawaddy Formation in the Migyaungye- Kunon Area, Magway Township, Magway Region" Warr Warr Thidar Swam Khin San Zin Maung Maung Thein Soe Myint "Migyaungye- Kunon area is situated far about 40 miles from the eastern bank of the Ayeyarwaddy River in the southeast of Magway Township,. It is located between the latitudes 19º 53' N and 19º 59' N and between the longitudes 95º 06' E and 95º 14'E, referring to UTM topographic map 1995-01 (85 M-1). The sedimentary rocks found in the study area are subdivided into two formation based on the lithologic and faunal characteristics. They are Irrawaddy Formation (Late Miocene to Early Pleistocene) and Obogon Formation (Middle Miocene). Section measurements were particularly made in detailed along the well exposed sections which are perpendicular to structural trend. In the present study area, the Irrwaddy Formation is well exposed along the Ye Ngan Chaung, Sadaung Chaung and Kun on Chaung section. At least (9) lithofacies can be recognized and there are grouped into (3) lithofacies association of the Irrwaddy Formation, according to the feature of lithology, texture, sedimentary structures, fossil contents, etc. They are (1) Channel facies association, (2) Overbank facies association and (3) Flood plain facies association. According to the facies association and sedimentary characters, the Irrwaddy Formation is assigned to be deposited under meandering river dominated fluvial environment." 2022-08-12 https://meral.edu.mm/records/8408
