I Indonesia sits on the pacific ring of fire, thus the geothermal energy potential is verylarge and needs to be developed. This encourages researchers to find out how thegeological structure affect the geothermal energy. The research area is located in theCisolok area, Sukabumi District, West Java Province. This research was conductedto find out the geological conditions in the research area that was focused ongeological structures that developed in the research area and influenced thesestructures towards the manifestations of geothermal manifestations. Data collectedby geological mapping and fracture measurements in the field using the scanlinemethod supported by the Fault Fracture Density method. Geomorphology of thestudy area is divided into two units, namely the Dendudational Hills GeomorphologyUnit and the Faulty Zone of the Sharp Hills Geomorphology Unit. Geology of thestudy area is divided into four units, namely Limestone Unit, Dacite Unit, AndesiteUnit, and Tuf Unit. The geological structure of the research area is divided into 5,namely Cipanas Dextral Strike Slip Fault, Cisolok Sinistral Strike Slip Fault, CitiisDextral Strike Slip Fault, Pasir Hawu Sinistral Strike Slip Fault and Citemen ThrustFault. The movement of Cipanas Dextral Strike Slip Fault and Cisolok SinistralStrike Slip Fault plays an important role in forming the permeability zone.Geothermal model of Cisolok Area shows an outflow zone, permeability zone , andVulcanic Hidrothermal type with high relief-liquid dominated system.
