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

开展了沿Alarcon盆地、Guaymas盆地和Delfin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（研究南向北海底扩张到非扩张模式）和沿Wagner盆地的东西向剖面（研究深部低角度滑脱断层）的地震和构造地质实验。研究的问题包括：应变分配、裂谷岩浆活动的体积和侵位方式、伸展方式的沿轴差异以及沉积对变形的影响。计划在今后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.
