| Abstract | Waesalit geothermal field lies aproximately 60 km SW of Namlea, the Capital City of Buru Regency, Maluku Province. Geophysical methods (gravity, geomagnetic and resistivity) were carried out to delineate the structural traps of a non vulcanic hosted geothermal field in Waesalit, Buru Island-Indonesia. Geophysical data indicates moderate to high gravity and low geomagnetic anomalous around the Waesalit hot water, whilst the resistivity data show the resitivity value around the hot water is relatively high ( 20 – 110 ohm-m) compare to the value of a volcanic geothermal sytem (10 – 20 om-m). Based on geophysical data, the structural traps of a non vulcanic hosted geothermal field in the area is relatively similar to volcanic hosted geothermal area, whilst the heat source is considered to be associated to volcano-tectonic process on metamorphic rock. |
