| 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.
