[Withdrawn] 1D Inversion of Magnetotelluric Data From Ashute, Butajira Geothermal Prospect, South-East Ethiopia and Its Geothermal Implications

Geophysical surveying is one of the Earth science disciplines which is used for exploration of geothermal energy. Magnetotelluric (MT) survey was conducted in Ashute Geothermal prospect area acquiring 28 soundings. North-South of the major hydrothermal manifestations in the Ashute field and to make the suggest cross-section maps and 1D inversion model, to study the subsurface resistivity structure of the geothermal system at the Ashute, Butajira field, its relation to the geothermal field marked Aligned volcanic cones and the group of thermal spring in the axial part of Debre zait Selti graven suggest the main NE – SW Debre zait Selti fault system and transverse NW – SE older rift structure beyond to control Magmatism (heat source), water recharge and permeability of the system. The trend of high and low resistivity anomaly and the discontinuities (NE-SW alignment) structure and transverse NW-SE faults and opening fissures, that indicated the possibility of the connection of the Ashute, Butajira geothermal systems. In Addition to this MT soundings towards NE-SW Ashute geothermal field and BTJ-068 in the Ashute field and reinterpretation of result using TEM data were recommended for a better definition of the anomalies and achieve the stated objectives.
