【 摘 要 】

The chemical elements making up the rocks located on the coastal areas in the Eastern Bolaang Mongondow were successfully mapped and investigated by employing the XRF method. The rocks collected from the Central Buyat, South Buyat, Motongkat and Jiko coastal areas of the sub-districts were milled until the size was close to 120 mesh. The samples were characterized and measured to obtain the chemical elements deposited inside the rocks. It was found that the elements which make up the rocks are relatively different depending on the coastal locations. The silicon (Si) was the highest percentage of all elements found and followed by iron (Fe), calcium (Ca) and aluminum (Al). The composition of Si deposited in the rocks from Buyat coastal area was of 42.4% which the biggest percentage compared the rest of the samples. The Iron (Fe) element had a chemical composition recorded at 28.9% that was the highest figure in which rocks were obtained from Jiko coast. The aluminum (Al) composition was relatively similar for all samples collected from that location and observed at 10%.
