Lithospheric discontinuities, above all the Conrad (the upper-lower crust discontinuity), the Moho (the crust-mantle boundary), the MLD (the intra upper-mantle lithosphere discontinuity), or the LAB (the lithosphere-asthenosphere transition), are fundamental tectonic features offering key insights into structure and evolution of both the continental and/or oceanic plates. The prominent discontinuities broaden our view on plate-tectonic processes including the natural hazard. This session welcomes contributions that explore various geophysical methods of discontinuity imaging, particularly active and passive seismic, gravitational, magnetic ones and especially their combinations. We also invite case studies of the lithospheric boundaries at regional and global tectonic scales, as well as novel interpretations of lithospheric discontinuities from multidisciplinary perspectives, including geology, geochemistry, and geodynamics.
