General Geology of Temerloh - Jerantut Transect with Emphasis on Depositional Environment

General geology of the Central Pahang is dominated by the presence of Permian and Triassic age sediments. The Permian sediments are composed of interbedded series of black limestones, calcareous shales, sandstones and a band of conglomerate. Semantan Formation consists predominantly of deep marine, possibly bathyal (slope) sediments and there are also signs of turbidite sediments from lithological characteristics, sedimentary structures and fossils (Madon, 2010). Only the Semantan sediments will be analysed in this study. The sediments comprise of thinly and thickly bedded tuflaceous sandstone and interbedded mudstone and shale .The tuffaceous sandstone is well bedded greyish orange colour and it occur with sharp plane top and basal contact with the alternating mudstone and shale beds. As the Mesozoic stratigraphy in the Central Belt is largely controlled by tectonics, this study will be important to integrate the tectonics events that happened which influence the relative uplift and subsidence of the area, which eventually affected the depositional style and sediments in the basins in order to established a complete and better understanding stratigraphy of the Semantan sediments in Peninsular Malaysia. All information gathered will be used to make the geological map and cross section of the transect area. Petrography works from the thin section will provide details on texture and grain size of the rocks and also the origin of the rock itself. Correlation between field data and laboratory analysis such as gas chromatography, microfossils analysis and FTIR will help in classifying the depositional environment. Finally, model of the depositional environment can be modelled based on the features and data obtained from the laboratory analysis.
