| Abstract | In the collision zone between Arabia and Eurasia, the Plio-Quaternary of Sabalan volcano, in NW Iran has been identified as a major geothermal field in Iran. A detailed surface and sub-surface exploration program have carried out in last 20 years. The data related to 11 exploration wells of NWS1 to NWS11 are compiled. Data integration including structural, stratigraphy, alteration and mud loss data indicates that structural trends and stratigraphy play a major role in the hydrothermal regime. 3D modelling of the main structures combined with mud loss data, it appears that some faults indicate a combined conduit-barrier permeability structure. Caldera structure in the high depth behaves highly permeable. |
