Volcanostratigraphy of Batukuwung-Parakasak Geothermal Area, Serang Regency, West Java

Abstract

Geothermal resource and reserve have been utilized at Batukuwung-Parakasak area, Serang Regency, West Java. As in general geothermal areas, geologically there are volcanic rocks distributed in the area. Structural as well as lithological condition are causing geothermal fluids exposed as hot water springs around the area. Regional geologically, there are four lithological units, the whole are of Quartennary age. By applying volcanostratigraphic method, it can be mapped into nine volcanostratigraphic units. Based on volcanostratigraphic principles there could be interpreted volcanic process that have been controlled the volcanostratigraphic litology units' generation. Concerning the geothermal potential, volcanostratigraphic geological mapping has helped understanding the geothermal system modelling of the area, further contributed to the geothermal exploration as well as utilization activities.
