Abstract:
In this paper, we discuss acquiring, processing and preliminary modelling of multidisciplinary geophysical data (i.e. seismic, magnetotelluric, potential field data and petrophysical characterisations) to reliably model subsurface features along the transects. Across the Swayze transect, seismic sections clearly show sub-horizontal and dipping geological boundaries and magnetotelluric model reveals pathways as narrow upper crustal sub-vertical zones of low resistivity. In addition, joint inversion of gravity and magnetic data on initial models constrained by surface geology, seismic and magnetotelluric models and petrophysical characterisations have improved the models by better detecting at depth the limits of lithological units, low-density batholiths, dykes and fault zones.
