A Study on clay minerals and major element oxides in surface riverine estuarine sediments from selected from selected rivers of Terengganu, Malaysia

Abstract

The clay mineralogy deposition and major oxide elements distribution of the surface estuarine sediments from the selected estuaries of Terengganu was studied in order to know the types of clay minerals and the source of sediments. A total of 68 sampling stations were collected from the estuaries of Terengganu River, Kemaman River, Dungun River and Besut River. The sediments were examined using X-ray Diffractometer (XRD) and Scanning Electron Microscope with Electron Dispersive X-ray Spectroscopy (SEM-EDS) methods for the clay minerals present and major oxides composition.
