Structure, Tectonics and Sediment Flow into the Lesser Antilles Subduction Zone

小行星9617751 这是对巴巴多斯海岭增生楔的一次调查，目的是利用地震反射剖面对楔的背面进行成像，并利用OBS仪器记录的广角反射/折射数据获得楔背面和后挡板的详细速度模型。 其目标是确定后挡板、俯冲洋壳和增生楔后部的几何形状和结构，以解决质量平衡、孕震区和其他构造问题。

9617751 Bangs This is a survey of the Barbados Ridge accretionaly wedge designed to image the back of the wedge with seismic reflection profiling and to obtain a detailed velocity model of the back of the wedge and backstop with wide-angle reflection/refraction data recorded on OBS instruments. the goal is to define the geometry and structure of the backstop, the subducting ocean crust, and the back of the accretionary wedge to address mass balance, the seismogenic zone, and other tectonic questions.
