Abstract

Sorik Marapi geothermal area in Mandailing Natal Regency, North Sumatra Province has a high-temperature geothermal system that is interpreted from the chemical characteristics of hot springs. The presence of alteration minerals such as epidot in exploration well cutting samples strengthens the estimated reservoir temperature reaches 235⁰C. The presence of hot water are more acidic hot spring around fumaroles and the minerals obtained from the drill well reflect the upflow zone while the hot spring group of neutral chloride water in the north with lower elevation reflects the outflow zone of the geothermal system here. This is a characteristic of hot fluid flow that occurs in geothermal areas of volcanic systems with steep terrain as well as Sorik Marapi area.
