In this work, the electrical resistivity of the subsurface is studied. Geophysical exploration methods to be used are discussed in some details. The joint 1-D inversion of TEM and MT data is performed. The static shift problem of MT data is solved by inverting jointly both TEM and MT data. The resistivity of the subsurface correlates with the alteration mineralogy studied in drillholes. The NW-SE profile of the Krýsuvík area appears to host a viable geothermal system. However, a discrepancy is raised between the formation and the alteration temperatures, which would mean a cooling geothermal system underneath the studied profile. |
