High mantle seismic P-wave speeds as a signature for gravitational spreading of superplumes
New passive- and active-source seismic experiments reveal unusually high mantle P-wave speeds that extend beneath the remnants of the world’s largest known large igneous province, making up the 120-million-year-old Ontong-Java-Manihiki-Hikurangi Plateau. Sub-Moho P(n) phases of ~8.8 ± 0.2 km/s are r...
