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.

提供了用于地震和结构地质实验的资金，以描绘沿Alarcon，Guaymas和Delfin Basins的三个主要结合边缘的地壳延伸和裂谷岩浆的几何形状和模式（以研究南部到北部的Seaforeking to to to north Seafection to to nort e-eplenting Mode）以及沿着e-Wagner base（沿着e-e-e-Wagner specter）（沿着wagner base）进行研究。要解决的问题包括，裂谷岩浆的应变分配，体积和安置样式，延伸样式的轴差异以及沉积对变形的影响。计划在未来三年内进行一项综合土地研究。
