Abstract

• The research area is situated within the Chindwin Basin of Central Myanmar Belt in which the Cretaceous to Neogene sediments were deposited. Pondaung Formation consists of thick to massive, light greenish grey, hard and compact, fine to coarse-grained sandstones intercalated with light grey shale, siltstone. Moreover, there are also many gravels, pebbles, sub-rounded to rounded gritty sandstone and conglomerate bands, sandstone concretion, the laminated shale and variegated clay occurred in the study area. The heavy minerals are a very important group of minerals existed in clastic sedimentary rocks because they are provenance indicators of the source rocks. The provenance of the Pondaung Formation is interpreted as igneous rocks from the Wuntho-Popa arc based on the heavy minerals. The Pondaung sediments range from moderately to poorly sorted, positive skewed, leptokurtic to mesokurtic, two segments that indicate the medium to high energy condition during deposition. Due to these results, the Pondaung Formation was deposited in the fluvial dominated deltaic environment derived from igneous rocks of Wuntho-Popa arc.
