Recent progress in understanding the Mesozoic opening of the Gulf of Mexico basin and its subsequent passive margin history

Because of its thick Cretaceous-Cenozoic sedimentary fill up to 20 km, the early opening history of the Gulf of Mexico has remained speculative for decades.  I summarize recent progress using geophysical methods that include refraction, deep-penetration seismic reflection, gravity and magnetics.  These data constrain a two-phase opening model with a late Triassic-early Jurassic northwest to southeast opening followed by a counterclockwise rotation of the Yucatan block and formation by an arcuate area of oceanic crust that underlies the central area of the basin.  I will also summarize the subsequent Cretaceous-Cenozoic events that have shaped the “passive” margins of the basin that include: 1) the Laramide and younger orogenies in Mexico; 2) the Cuban arc collision, 3) the Chixcilub impact, and 3) deep burial of the western and northern margins by terrigenous sediments and formation of several passive margin fold belts.

Event will be hosted as a webinar. Registration can be found here.

For outside visitors, the best way to get to our department is to come in on Rice Blvd and turn left into entrance 20 (intersection of Rice and Kent St.). At the stop sign, you will see a visitor parking lot on your right.  From there, walk east to the department.  The google map below shows exactly where our building is.
