| Abstract | The main objectives of this study are to determine the sedimentology, stratigraphy and depositional environment of the redbeds in Laem Thai Ran Dok Mai. In this study, 6 lithofacies are classified based on field work, thin section analysis and spectral gamma signatures which are shale, fine to coarse sandstone, coarse sandstone with clasts, granular sandstone, pebbly sandstone and conglomerate. These redbeds mainly contain sandstones. In the lower part, sandstones interbed with conglomerates, some pebbly sandstones and granular sandstones. Generally, spectral gamma signatures match quite well with sedimentary features. These redbeds were deposited by a braided stream system. Based on their characteristics, these redbeds are interpreted as belonging to the Nam Phong Formation. These rocks have poor reservoir potential because of low porosity. They are compacted, strongly influenced by diagenesis and filled by infiltrated clay. |
