Initial assessment of the Tinoc Geothermal Prospect in Ifugao suggests the existence of a geothermal resource in the area. This is based on the results of geological and geochemical surveys earlier done in the area and the recently conducted Schlumberger Resistiviy Traversing (SRT). The prospect area exhibits impressive thermal manifestations, in the forms of warm to hot springs, boiling pools, solfatara, gas seeps and altered ground. Mention made geochemical thermal to Prospect geochemical Republic Cooperation Development, Four lithologic units were identified in Tinoc, i.e. dacitic lava flows, pyroclastic rocks, diorite and meta-sedimentary rocks. Major structural features dominating the area are the NE-SW and N-S trending faults. The NE trending faults traversed along areas of hot springs and solfatara. The probable heat source of an intermediate temperature geothermal system at Tinoc could be associated with the Quaternary dacite lava dome of Mt. Tebeyo.

Chemistry of the waters however does not indicate the presence of a mature geothermal system. Geothermometry indicates a subsurface temperature of around 160░C. There are evidences to suggest on the presence of a more saline parent water possibly at higher temperatures but tends to be rich in sulfate at depth. Results of resistivity traversing at AB/2=500 m delineated an anomaly that is possibly related to the occurrence of a geothermal system. Although this seems to be localized and confined along the thermal manifestations in Tukucan and its vicinities, there is a possibility that this anomaly could widen at depth. Deeper probing geophysical methods are recommended to determine the extent of the resource and resistivity distribution at depth. Barangay relatively rugged |
