Abstract

The geochemistry of ophiolite related serpentinite soils has been one of the most challenging concerns among soil scientists and ecologists for several decades. Despite increasing global knowledge about the specificity of serpentinites, they have received limited attention in Malaysia. Considering the role of climate in the chemical composition of the derived soils, this study focused on tropical serpentinite soils in Malaysia. A total of 27 soil samples was collected from five serpentinite outcrops in Peninsular Malaysia and Sabah and analysed elementally. Based on their major oxide contents, the soils were divided into two groups of ‘rich in Fe’ and ‘rich in Mg’ which represent mature and immature soils, respectively. However, the most striking result that emerged from this study was the anomalous concentration of three trace metals of chromium, nickel and cobalt in the studied serpentinite soils in comparison with those of the adjacent sedimentary soils (soils of Crocker). The observed elemental ranges were Cr 2,427-27,863, Ni 850-4,753 and Co 35-167 (in μg g-1), while the ranges for these elements for the soils of Crocker formation were Cr 67-182, Ni 33-270 and Co 11-23 (in μg g-1). It is obvious that the amounts of Cr, Ni and Co in the studied serpentinites soils were 105, 15 and 6 times higher, respectively, than those in Crocker soils comparing with the Dutch List standard and Great London Council guidelines, serpentinite soils of Malaysia can be considered to be heavily contaminated with Cr, Ni and Co.
