- Geoelectric strike and its application in magnetotellurics
- Bachelor's
Electrical resistivity methods in geophysical prospecting have been the most powerful
tool in geothermal exploration. Determination of geoelectric strike angle in magnetotelluric
(MT) measurements is a valuable contribution to an overall analysis of
resistivity data. Among the applications of the strike analysis are the delineation of
the boundaries of geothermal reservoirs and determination of fractures and faults
at different depths which are the ideal flow paths of geothermal fluid. Strike analysis
reveals complexity of resistivity structures within geothermal areas. Four MT
soundings were conducted on Reykjanes peninsula in May 2014 and the data were
compared with results of strike analysis from Krafla and Námafjall. Similarity in
geoelectric strike behaviour in high-temperature areas confirms the results of inversion
of resistivity soundings. The strike angle is found by rotation of the impedance
tensor by a certain angle which in turn minimizes diagonal tensor elements Zxx
and Zyy.
