| Zusammenfassung: | <jats:title>Abstract</jats:title> <jats:p>Bonjol geothermal area is located in Pasaman Regency, Province of West Sumatera. The existence of geothermal system is characterized by hot springs, and rock alterations by temperature 50 - 88°C. Magnetotelluric (MT) survey had been conducted by Geological Agency in 2009 and 2018 to identify the geothermal promising zones. Utilizing 2D inversion model of MT data can delineate the conductivity structure to identify where geothermal system is located. MT data result showed that low resistivity in the northern part is around Takis, Sungai Limau, and Kambahan hotsprings, and in the southern part is around Padang Baru hotspring interpreted as cap rock of Bonjol geothermal system. The existence of top reservoir of Bonjol geothermal system is about 800 until 1000 meters depth. The promising area are located in the northern part area around Takis, Sungai Limau, and Kambahan hot springs, and in the southern part area around Padang Baru hot spring.</jats:p> |
