Seismic models correlation with
resistivity models
Profile DD' resistivity model show a conductive anomaly
vertically extensive parallel to Tamazula fault plane and an
horizontal extensive sill complex around 20 km depth.
Velocity model from Sychev et al. (2019) elucidates an
anomaly. Low velocity zones correlate with our conductive
body.
