  • Abstract

    This research is aimed to study the mineral composition of alterations rock in Lahendong geothermal manifestation area, North Sulawesi. This research is using Scanning Electron Microscopic-Energy Dispersive X-Ray Spectrometric (SEM-EDX) and Fourier Transform Infra Red (FTIR) characterization method. The result of the characterization using SEM-EDX shows that the warm ground contained the mineral silica, while the steaming ground contained the kaolinite clay. The rock elements of the warm ground consist of O 71.90% and Si 28.10% with O dominating, this is indicate that the rocks have high porosity, while the rock elements of the steaming ground consist of O 56.86%, Al 1.94%, Si 3.52% and C 7.25% is coating material sample for energy dispersive x-ray spectrometric as penetrate in this rock sample. This result is consistent with the characterization using FTIR.
