عنوان انگلیسی Identification of subsurface structures and potential reservoir zones of geothermal filds based on gravitr data analysis in the Karaha-Cakrana area, west Java
چکیده انگلیسی مقاله The Karaha-Cakrabuana area in West Java is believed to contain geothermal prospects. The discovery of geothermal manifestations in the form of fumaroles and hot springs requires further development for optimal utilization. This research aims to identify subsurface structures and potential reservoir zones using gravity methods. The research data consist of GGMplus satellite gravity data, processed using Geosoft Oasis Montaj software, and modeled using ZondGM2D. The results of the Second Vertical Derivative (SVD) curve analysis indicate the possibility of both thrust and normal faults. The SVD graph analysis reveals the presence of eleven fault structures, including eight assumed variations of uplift fault structures and three variations of normal fault structures. Faults are believed to exist in specific locations in the foothill region of Mount Talaga Bodas, in the vicinity of Mount Talaga Bodas, at the base of Mount Sawal, and in the area of Karaha Crater. The 2D inversion modeling results identify rocks based on density distribution patterns, namely densities of 1.027 gr/cm3 - 1.6 gr/cm3 and densities between -2.06 gr/cm3 - 1.32 gr/cm3, suggesting tuff and lahar rocks. Densities of 1.68 gr/cm3 - 2.01 gr/cm3 and 1.8 gr/cm3 - 3.74 gr/cm3 suggest breccia and tuff rocks. Densities of 2.09 gr/cm3 - 2.18 gr/cm3 and 4.22 gr/cm3 - 4.7 gr/cm3 are indicative of andesite lava.
