中文摘要
为了了解海内弧的形成过程,我们利用伊祖弧北部已有的地震资料进行了地幔楔体地震层析成像。地幔成像结果表明,在厚岛弧地壳下存在低速地幔楔。在地幔成像的基础上,进行了OBS实验,获得了伊豆-波宁弧南部的新地震资料。
英文摘要
In order to understand formation processed of an intra-oceanic arc, we performed seismic tomography for mantle wedge imaging by using existing earthquake data in the northern Izu arc. Results of mantle imaging shows that there are low velocity mantle wedge beneath areas where thick island arc crust is observed. In addition to the mantle imaging, we carried out OBS experiment to obtain new earthquake data in the southern Izu-Bonin arc.
