Abstract:
The study was conducted to determine the sediment types and mineral contents in Johor
coastal sediments. The sediment samples were collected from thirty stations at the Johor
coastal area (South China Sea) using the Smith McIntyre Grab operated from the
Fisheries Department vessel KL CERMIN. Sediments collected were put in labeled
plastic bags and then were brought back to the laboratory for analysis. These sediments
were air-dried for sample preparation. For the purpose of this study, the sediment samples
which are sandy are not considered in the analysis. Only twenty sediment samples out of
the thirty stations were taken. Mineral contents in the sand and silt fractions were
determined using petrographic microscope. While the clay minerals in sediment were
detected using the Scanning Electron Microscope (SEM).
