Abstract

The Endut geothermal prospect area is located in Lebak district, Banten province, about 40 km in the southern Rangkasbitung city. This area has been surveyed by PSDG (Pusat Sumber Daya Geologi) since 2006. In this survey, data acquisition has been performed by using the resistivity methods with Schlumberger configuration from southwest to northeast. Local hot spring Cikawah (CKW) manifestation dominated by quaternary volcanic rocks of Mount Endut product that intruded tertiary sedimentary bedrock. Horizontal fault and normal trend rejuvenation of the northeast - southwest was expected control hot spring manifestation in Cikawah. Geothermal manifestations such as hot water Cikawah has the highest temperature (88 °C), the hot water discharge 5 L/sec, neutral pH, chloride type, in partial equlibrium, and there are in the between of the balance of Cl-Li-B. Resistivity data shows conductive layer at a depth of approximately 500 meters below Cikawah hot spring, which is suspected to be associated with the argillic alteration intrusive rocks. The high resistivity anomaly is suspected to be associated with thick igneous intrusive rocks.
