Integrated Gravity Interpretation for Hidden Geothermal System In Cipanas, Tasikmalaya Regency, West Java
Cipanas Geothermal Prospect in Tasikmalaya Regency is classified as a hidden geothermal system, thus gravity surveying plays an important role in early stage of subsurface imaging. Totally 165 gravity stations has been observed with 1.5-2 km spacing grid within 25 x 27 km area coverage using LaCoste-Romberg G-series gravimeter. An integrated gravity interpretation including horizontal and vertical gradient analysis, power spectral analysis, Euler Deconvolution, 2-D forward modeling, 2-D inversion modeling and 3-D inversion modelingare provided in this study to recover geological features that occurs on the geothermal system. As the results, we could estimate the location and depth ofheat sources and deep geological lineaments that control the Cipanas Geothermal Prospect.
