Quarternary Sediments at Sungei Besi, West Malaysia


University of Malaya


Abstract: Well stratified sediments consisting of gravel, sand, mud, clay and peat crop out in several opencast pits of the Sungei Besi Tin Mines near Kuala Lumpur. They lie unconformably over limestone and granite bed rock with their base below the present sea level. Pollen analyses and carbon-14 dating indicate that most of the sediments are Pleistocene in age. Abundant plant fragments, the lack of marine fossils, and the occurrence of gravelly lenses suggest a fluvial depositional environment. The dominance of angular grains of quartz, tourmaline and muscovite in these sediments indicate that they were derived from weathered granitic rocks nearby. The depositional history was probably related to the sea level changes during the Pleistocene.
