Taburan Geokimia Unsur Sedimen Kuaterner Laut Cetek Muara Sungai Kelantan hingga ke Pelantar Laut China Selatan, Semenanjung Malaysia

The geochemical analysis using ICP-MS method showed that the geochemical distribution of elements influenced by two sediment origins: From marine and terrestrial. Ca and Mg were identified as marine elements, while Al, Fe, Mn, Na, Cu, Cr, Zn and Ni were identified as terrestrial elements. The Ca and Mg elements were derived from decalcification o f skeletons of marine life such as mollusc and foraminiferas. Continental elements might have originated from granites of Gunung Korbu and Gunung Stong which are drained by Sungai Nenggiri and Sungai Galas, while and argillaceous arenaceous rocks from the south and southeastern parts of Kelantan state which originated from Gunung Cintawangsa and Gunung Stong are being drained by Sungai Lebir and Sungai Galas. These parent rocks have released their chemical elements during a chemical weathering and the elements have been absorbed by negative charges on the surface of fine sediments such as clay and silt before being deposited in the study area.
