A sediment core was collected from Terengganu’s offshore to determine vertical profile
and concentration of major, minor and trace elements. These elements was analysed
using X-ray Fluorescence. Significant concentration of elements can be found from
90cm to 186cm depth. This might due to the declining in water content that reflects
increasing of compaction of the sediment and the clay sized sediment domination. The
major elements exist in the core are SiO2>Al2O3>CaO>Na2O>Cl>MgO>Fe2CO3>K2O.
SiO2 (62.03%) dominated this study area indicate that Terengganu’s water is highly
siliceous. Meanwhile for minor elements are TiO>P2O5>MnO>Zr>Sr>Cr>Pb>Zn>Cu.
TiO (0.63%) and Zr (494.27ppm) are represent highest concentration for minor
elements. V>Ce>Rb>Ni>Sc>Ga are the trace elements that can be found in the
sample. Concentration of V (61.3ppm) has shown increasing pattern along the core
sample. Based on this study, geochemical properties in Terengganu’s offshore are in
the low range of concentration compared with other studies in Malaysia.
