| Abstract |
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. |
