SEismic imaging of the Ivrea ZonE
SEIZE is the active seismics part of the ICDP-proposal DIVE (Drilling the Ivrea-Verbano ZonE). The Ivrea-Verbano Zone (IVZ) in the Italian Alps is one of the most complete and most studied, time-integrated arche-type of continental crust–upper mantle section on Earth. Moreover, it provides the best natural laboratory to significantly advance our understanding of the continental lower crust and crust–mantle transition zone by a combination of geoscientific approaches and scientific drilling. Drilling a 4-km deep hole in the IVZ will provide an unrivalled opportunity to link geophysical and geological data via core observations, downhole logging, microbiological sampling, hydrological studies, and various geophysical-geological surveys around the borehole area.
SEIZE provides the seismological image of the upper crust in the Balmuccia area needed to plan, execute and interpret the results of the ICDP drilling.
