Imaging Deep Slab Structure Using Shear Waves

本项研究旨在确定 俯冲的千岛群岛和日本岩石圈板块， 差分剩余球程序。 过去的研究 主要集中在P波速度结构上， 关于结果的争论仍在继续，特别是 板块穿透下地幔 S波更难 但现在由于技术的进步， 仪器仪表 S波对热辐射和 化学结构的板坯，并可能有助于解决基本的 关于地幔动力学的问题

This research is to determine the S-wave velocity structure of the subducting Kurile and Japan lithospheric slabs using differential residual sphere procedures. Past studies have concentrated mainly on P-wave velocity structure, and considerable controversy continues about the results, especially whether the slab penetrates the lower mantle. S-waves are more difficult to measure but are now accessible because of advances in instrumentation. S-waves are more sensitive to the thermal and chemical structure of the slab and may help resolve fundamental questions about mantle dynamics.
