Abstract
The fault system surrounding the Ulubelu geothermal prospect contributed 20 major fault system which have been analysed thoroughly. Thoso faults are identified as F1 to F20. The faults F3, F4, F7, F11, F15 and F16 were predicted as strike slip faults. Either faults F1, F2, F5, F6, F8, F9, F10, F12, F13, F14, F17, F18, F19 and F20, were predicted as reverse either normal fault. The relative ages of the faults are approximately between Pleocene and.Pleistocene. The faults F1, F2, F3, F4, F5, F7, F8 and F11 have relative ages Late Pleistocene. The faults F6, F10, F13, F14, F17 and F18 have relative ages Mid Pleistocene. The faults F9, F19 and F20 have relative ages Post Pleistocene. Furthermore the faults F12, F15 and F16 have relative ages Late Pliocene. The lithologies surrounding the geothermal system contributed of: Firstly, the formation and rocks, that occur at Holocene Era consisting of the alluvium, alteration rocks and Ranau Formation. Secondly, the rocks, that occur at Pleistocene Era consisting of the Mt. Kurupan ryolitc lava, the Mt. Rendingan andesitic lava and pyroclastic, Mt. Tanggamus breccias lahar and andesitic lava,and the Mt. Kabawok pyroclastic. Thirdly, the rocks, that occur at Pliocene Era consisting of the Mt. Duduk dacite lava, the Mt. Kukusan basaltic lava, and the Mt. Sulah andesite lava. The lastly, the rocks and formation that occur at Miocene Era consisting of the granodiorit intrusion and Hulusimpang Formation. Key word: fault, relative ages, geothermal, lithology
