PI 将进行高分辨率地震勘测,以对戈尔达悬崖南翼的结构以及悬崖和门多西诺山脊之间的过渡区进行成像。 调查的目的是确定文卡诺地块中是否存在原始圣安德烈亚断层或地块与山脊之间的缝合线。 悬崖隆起的时间将受到限制。 这将有助于深入了解戈尔达板块地壳向太平洋板块转移的过程,并了解板块边界动力学和演化。
英文摘要
The PIs will carry out a high-resolution seismic survey to image the structure of the southern flank of the Gorda Escarpment and the transiition between the Escarpment and Mendocino Ridge. The survey will be carried out to determine whether there are proto-San Andrea's faults in the Vincaino Block or sutures between blocks and the Ridge. The timing of the uplift of the Escarpment will be constrained. This will lead to an insight into the processes that are responsible for the transfer of the Gorda Plate crust to the Pacific Plate and the understanding of the plate boundary dynamics and evolution.
