| 英文摘要 | Using the Pn tomography method and new ISC-EHB data, we obtained a new Pn velocity and anisotropy model of the uppermost mantle in eastern Caribbean. The consistency between the Pn fast directions and SKS splitting fast wave directions indicates that the anisotropic structure of the uppermost mantle in the area of the collisional plate boundary is the main cause of shear-wave splitting. The results show that the seismic velocity of uppermost mantle beneath the Aves Ridge is not anomalous, implying that this area is no longer affected by the upwelling of mantle material. We observe high Pn velocities in the uppermost mantle beneath eastern Caribbean Sea, which are higher than in the deeper parts (100-200 km in depth) of the upper mantle; comparing these results with similar findings in the Japan Sea at the northwestern Pacific subduction zone, we believe the uppermost mantle beneath the back-arc region is not or little affected by hot material from the deeper mantle. |
