An Integrated Geophysical Approach for Sub Basalt Exploration

We discuss an integrated work flow applied to multidisciplinary data acquired at two different scales. First, we performed an integrated geophysical experiment (on land) at relatively small scale. We performed a multidisciplinary survey along a line running on a lava flow outcrop. Our objective was to acquire a seismic and electromagnetic data set in correspondence of a basalt outcrop overlaying a well known sedimentary sequence. Using this data set we tested an integrated interpretation work flow based on modelling and inversion of complementary geophysical data. The objective was to verify if and how seismic and electromagnetic data can be combined for obtaining an improved imaging of the basalt and sub basalt sequences. Then we applied our integrated work flow to a multidisciplinary data set acquired in a much larger geological context in offshore Norway.
