Abstract

Resistivity structure identification of magnetotelluric data was made at geothermal area“T”, located in southern Indonesia. This process is based on the modeling result of 2-dimention magnetotelluric data. The modeling result of magnetotelluric data shows relativity structure dissemination on a scale of 0-10 ohm.m in a thickness of 1 km (clay cap), on a scale of 10-100 ohm.m in a depth of 1-2 km (reservoir zone), and on a scale of 100-1000 ohm.m in a depth of 2-3 km (heat source zone). The result of relativity structure dissemination can be used to delineate an area with geothermal prospect around 12 km2. Keywords: magnetotelluric, 2 dimension modeling, structure resistivity
