Taylor0099277The gulf of Corinth is an active continental rift with high seismicity and extensional strain. The bunding faults are high angle where they are exposed at the margins of the Gulf, but become much more shallow dipping at depth. The mechanisms of faulting and extension are poorly understood, but are similar to that observed in other rifted margins. The primary deformation is focused beneath the Gulf making the use of marine seismic reflection profiling the best technique to directly image these features.The present project will use the RV Ewing to acquire 1o days of multi-channel seismic reflection data from the Gulf of Corinth rift. Primary analyses will be focused on determining the mode of deformation and how it varies along strike. The project will be an important step in determining how exposed deformation relates to evidence of deformation at depth, and hence the dynamics of the faults in this area. The project will be undertaken in cooperation with Greek and French scietists.

科林斯湾是一个活跃的大陆裂谷，具有高地震活动和伸展应变。在海湾边缘暴露的地方，捆绑断层是高角度的，但在深部变得更浅。断裂和伸展的机制知之甚少，但与在其他裂谷边缘观察到的相似。原始形变主要集中在墨西哥湾以下，利用海洋地震反射剖面是直接成像这些特征的最佳技术。本项目将使用RV Ewing从科林斯湾裂谷获取10天的多通道地震反射数据。主要的分析将集中在确定变形模式以及它如何沿走向变化。该项目将是确定暴露的变形如何与深部变形的证据相关联的重要一步，从而确定该地区断层的动力学。该项目将与希腊和法国的科学家合作进行。
