seismic tomography; p and PP waves; mantle Diffraction theory predicts that traveltimes of seismic waves with a finite dominant frequency are affected by heterogeneities within a narrow region around the ray-theoretical path, called Fresnel zone. Because of wavefront healing, heterogeneities whose s...
