Sedimentary Structures of Neogene Clastic Sediments Exposed around Taungtha-Myingyan Areas, Mandalay Region Thu Rein Soe The current research area is located around Taungtha-Myingyan areas. The main objective is to describe the sedimentary structures on the bedding planes of Neogene clastic sediments from field observations and to estimate the possible depositional environments based on sedimentary process and condition. It is composed of light grey, reddish brown to buff coloured, fine to medium grained, thin-medium to thick-bedded, sandstones, shale and silty clay interbeds. The various types of sedimentary structures of Neogene clastic sediments include ripple marks, planar cross-bedding, bi-directional cross-bedding, parallel lamination, load cast, flute cast, mud clasts, concretions, cone-in-cone structure, convolute lamination, herringbone cross-bedding, hummocky cross-stratification, wavy bedding, lenticular bedding and flaser bedding. The possible depositional environments may be suggested as tide and wave deltaic and fluvial environments. This research provides the paleocurrent, paleoclimate, paleoecology and paleography for sustainable natural resource management. 2025-12-01 https://meral.edu.mm/records/12771
