| The study area is about 4 miles north of Pyin-Oo-Lwin. Topographic map of this area is 93 B/8. It is North Latitude 22 02' to 22 06' and East Longitude 96˚ 23' to 96 28'. The Paleozoic rock of the study area consist of in ascending order, Sitha Formation (Middle Ordovician), Kyaingtaung Formation (Upper Ordovician), Nyaungbaw Formation with Pan-Sha-Pye shale (Lower to Upper Silurian), Zebingyi Formation (Upper Silurian to Devonium). In the study area, the carbonate rocks are more abundant than clastic sediments. Among the stratigraphic units, the Nyaungbaw Formation is made up of carbonate rocks interbedded with siliciclastics units. Nyaungbaw Formation is extensively distributed the western and eastern part of the area. The rock of the lower member of Nyaungbaw Formation composed mainly of white shale with abundant graptolites are well exposed at east of Okhpo village. Graptolite; Monograptus sp, Climacograptus sp are found and which are indicate Silurian age. Moreover, the Nyaungbaw Formation can be measured from the base of the section to the top than the other formation of the study area. Microfacies analysis was detail study on carbonate rocks, mainly in the Nyaungbaw Formation. The section line exposed car road and this section have been measured bed by bed samples have been taken significant lithogic change, depending on facies changes. After studying field observation, thin sections and facies and microfacies has been constructed. There are two major depositional environments in the Silurian Nyaungbaw Formation on the basis of grain types, physical and biogenic sedimentary structures, and vertical facies relationships. In the study area, there are six microfacies and two lithofacies observed and they are grouped into two main facies associations such as inner shelf association and outer shelf association. |
