Margins: Collaborative Research: Seismic and Geologic Study of Gulf of California Rifting and Magmatism

为一项地震和构造地质实验提供了资金，以描绘沿阿拉康、瓜伊马斯和德尔芬盆地三个主要共轭边缘的地壳伸展和裂谷岩浆活动的几何形状和模式(以研究从南到北的海底扩展到非扩展模式)和沿瓦格纳盆地的东西向剖面(以研究深部的低角度滑脱断层)。需要解决的问题包括应变分配、裂谷岩浆作用的体积和侵位方式、沿轴向伸展方式的差异以及沉积作用对变形的影响。计划在未来三年进行一项陆基和海上综合研究。

Funding is provided for a seismic and structural geology experiment to delineate the geometries and patterns of crustal extension and rift magmatism along three main conjugate margins across Alarcon, Guaymas and Delfin Basins (to study the south to north seafloor-spreading to non-spreading mode) and a E-W profile along Wagner Basin (to study the low-angle detachment fault at depth). The questions to be addressed include, strain partitioning, volumetric and emplacement style of rift magmatism, along-axis differences in extension style and the influence of sedimentation on deformation. An integrated land-based and at sea study is planned for the next three years.
