| 英文摘要 | Temporary earthquake stations were installed on islands of Xisha Block and onshore-offshore deep seismic experiment was carried out in order to study the crustal structure beneath Xisha Block. The seismic data were analyzed and processed. A 1-D shear wave velocity model beneath Chenhang island (CHH) was constructed by applying receiver function method to the teleseismic data. A 2-D P-wave velocity crustal structure was modeled by ray-tracing and travel-time simulation. A 2 km-thick low-velocity sediment exists on the top of CHH which is attributed to Cenozoic deposition. In the lower crust, there exists a prominent Low-Velocity Layer (LVL) with average shear wave velocity of 3. 5 km/s; Moho interface lies at the depth of 24 26 km right beneath CHH. The crustal thickness gradually decreases outward along the onshore-offshore seismic line. The crustal structure has the typical characteristics of rift valley in the NW side of CHH, which belongs to the extension of Xisha Trough. The presence of anisotropy of upper mantle minerals and the ductile rheological structure arising from hot mantle activities may result in the generation of the LVL in lower crust. |
