| Abstract | Cipanas Geothermal Prospect in Tasikmalaya Regency is classified as a hidden geothermal system, thus gravity surveying plays in important role in early stage of subsurface imaging. Totally 70 gravity stations has been observed with 1.5-2 km spacing grid within 15 x 15 km area coverage using LaCoste-Romberg G-series gravimeter. An integrated gravity interpretation including horizontal and vertical gradient analysis and 3-D inversion modeling are provided in this study to recover geological features that occurs on the geothermal system. As the results, we could estimate the location and depth of heat sources and deep geological lineaments that control the Cipanas Geothermal Prospect. |
