Collaborative Research: Seismic Imaging of New Transitional Crust in the Salton Trough Oblique Rift

0742263孔摘要该项目将通过对索尔顿海槽的地震反射和折射测量来研究大陆岩石圈破裂的过程。这是研究岩浆作用和沉积作用对大陆伸展作用的影响以及岩石圈应变垂直分异的理想场所。这项研究的目的是调查裂陷大陆边缘过渡地壳的性质;岩浆活动在断裂最后阶段的作用;同裂谷沉积作用对岩浆活动和伸展机制的影响;高度倾斜大陆裂陷作用中的分割和位移;更广泛的影响包括实现MARGINS RCL倡议的重要目标，实现Earthscope和GeoSwath的目标。它使用Earthscope仪器。它将促进MARGINS、Earthscope和USGS之间的密切合作，并让本科生和研究生参与实地实验。它还将把实验纳入研究生课程，并让学生在收集到数据后参与解释。

This is an ideal location to study the effect of magmatism and sedimentation on continental extension and the portioning of the strain vertically in the lithosphere. The objectives of the study are to investigate the nature of the transitional crust at rifted continental margins; the role of magmatism in final stages of breakup; the effect of synrift sedimentation on magmatism and extension mechanism; the portioning and displacement in highly oblique continental rifting; and 3D structure for earthquake hazard evaluation.The broader impacts include addressing important goals of the MARGINS RCL initiative and contribute towards the goals of Earthscope as well as GeoSwath initatives. It uses Earthscope instrumention. It will foster strong collaboration between MARGINS, Earthscope and USGS, and involve undergraduate and graduate students in the field experiment. It will also incorporate the experiment into a graduate level course, and involve students in the interpretation of the data once it is collected.
