  13. Seismic anisotropy of the lithosphere: a relic of past deformation processes? Wagner et al., 2012

  14. Seismic tomography models derived from USArray data in the western US show a remarkable degree of robust, well-resolved heterogeneity on small spatial scales. • The interpretation of many of the features in tomography models is still open to exploration/debate. • Resistivity models obtained from the MT TA can provide constraints complementary to those obtained from seismic velocity models; joint interpretation can shed light on physical processes in crust and upper mantle. • Several new and exciting results relating to the discontinuity structure of the North American lithosphere. • Nature of LAB? Is the asthenosphere wet/partially melted? • Nature of MLD? • Anisotropic structure of lithosphere reflects past episodes of deformation. To what extent are these structures reflected in resistivity structure? Summary
