151. Subjected Ancient Slabs form Heterogeneous Seismic Scatterer at the Core Mantle Boundary
    Previous tomographic studies show that there is a ring of clear high-velocity anomalies around the Pacific Anomaly near the core–mantle boundary (CMB). However, because of inadequate sampling and limited resolution from conventional seismic phases, the detailed structure and origin of these an...
