Abstract: This study was conducted in order to determine the spatial distribution of sedimentological characteristics and heavy metal contents of Marang coastal sediment. The study area consists of 17 stations and sediment samples had been collected from 9 th th June till 11 June 2007. The analyzed data of sediment size and metals selected were mapped using Geographical Information System (GIS) with the Arcview approach. In general, the mean size of Marang coastal sediment ranged between 0.05 0 and 6.81 0 (fine sand) with poorly sorted (0. 72 0 and 2.00 0). Most of the stations were covered with fine sediment and had very positively skewed (-0.21 0 and 0.68 0) that proved an excess of finer grains. This might be due to the nearby river which is responsible to the transportation of sediments. The range of total organic carbon (TOC) content was between 0.12 % and 2.70 %. Concentration of heavy metals that had been detected using ICP - MS ranged from 207.06 to 833.23 µgig for Mn; 135.88 to 4179.10 µgig for Cr; 1.12 to 24.95 µgig for Co; 4.93 to18.44 µgig for Cu; 13.98 to 90.84 µgig for Zn; 0.03 to 0.09 µgig for Cd and 6.01 to 20.82 µgig for Pb. Correlation between percentage of TOC and particle size showed weak relationship (r=0.1658).
