Our in-depth interpretation of the data resulted in the detection of structural heterogeneities in the rift zones and active segments of the fracture zones, of a tract of sedimentary cover that shows evidence of several deformation phases, and of previously unreported volcanic edifices. In addition, a system of NW-SE trending strike-slip faults was established. The study shows that converting information from paper carriers to a digital format and combining the results with Internet resources and deep sea sampling data creates an entirely new dataset amenable to state-of-the-art processing techniques eventually leading to unexpected corollaries.
