Sipadan Island and Mabul Island are located in the south east coast of Sabah, precisely in the Celebes Sea. Sipadan Island is bounded by longitude 118° 3TE: and 118° 38'E: , and between latitude 4° 06'N and 4° 08'N. Whereas Mabul Island is set between longitudes of 118° 3TE and 118° 38'E and latitudes of 4° 14'N and 4° 15'N. The formation of both islands was due to the volcanic activity during the age of Quaternary. Originally deposited as coral reef; deposits of raised coral limestone, now overlie the Quaternary sediments and volcanic rocks. Eleven soil samples from Sipadan and twenty eight from Mabul were collected for geochemical analysis. These analysis consist of tests on pH, moisture content, organic content, particle size and concentration of four trace elements : - Cromium, Cuprum, Plumbum and Zink. Concentration of these elements are controlled by pH, organic content and particle size. Samples were found to be in the p11 range of 7 to 9. Their organic content is little, from 1.02% to 9.12% in Sipadan and 0.2% to 5.27% in Mabul. The concentration of each trace elements in Sipadan is as follows: - Cr : 1.4 ppm - 13.5 ppm, Cu : 29.6 ppm -- 4238 ppm, Pb : 0.4 ppm - 23.4 ppm and Zn : 5.7 ppm 52.8 ppm. Whereas in Mabul: - Cr : 1.3 ppm - 8.4 ppm, Cu : 0.6 ppm -- 61.4 ppm, Pb : 0.08 ppm 11.1 ppm and Zn : 1.2 ppm - 58.4 ppm
