| Abstract | Five bore holes were drilled for this study in Bangkok Metropolis region. Two of them are very deep and one of which met
the granitic gneiss bed rock. Other three are comparatively shallow. Undisturbed samples were available from the two deepest holes and disturbed samples were available from all the five. The sedimentary prism consists of alternating sand and clay layers. No sudden change from sand to clay or clay to sand could be observed. The change is gradational. The log probability grain size distribution
curves indicates that most of these sediments are deltaic, estuary, fluvial, marine or beach in origin. The log arithmetic grain size distribution curves indicates that most of these sediments were deposited in stagnate water. The saltation and suspension fractions
predominate in these sediments over the traction load. Majority of
these sediments are poorly sorted and only few samples indicate well sorting. The sand grains of all the samples are of subangular to subrounded and the sphericity is moderately high. The clay mineralogy proves that these sediments were deposited in slightly acidic to alkaline environments. The pH value of all the samples are in alkaline range. According to the other mineralogical analyses the source area which is responsible for these sediments consists
of low grade metamorphic rocks and igneous rocks. |
