Present research

Evolution and structure of the lithosphere through integrated geophysical-tectonic interpretation and acquisition of new field data. Development of geophysical methodology. Current projects concentrate on causes of uplift in regions of “passive margins”, such as around the North Atlantic Ocean far from plate boundaries, including acquisition and interpretation of new seismological data for providing structural control and development of geodynamic models to explain the uplift. Use of potential field data for derivation of mantle density for understanding topographic change and long-term stability of cratonic lithosphere. Causes of basin subsidence in terms of extensional forces, temperature evolution and magma transport.

Past research and key results

New understanding of the role of magmatism in underplating and at continental rift zones, including derivation of the model for “Magma-compensated Crustal Thinning” ; new model of basin formation based on magmatic intrusion; early identification of Proterozoic collision from seismic reflection and refraction; new model of the upper mantle based on identification of the upper mantle low-velocity zone (Mid-Lithospheric Discontinuity) and pronounced heterogeneity; explanation of the “teleseismic Pn wave” in terms of whispering gallery waves; the first ever reflection seismic image of Core-Mantle Boundary; determination of surface uplift from seismic velocity.
