Gulf of Mexico 1979, the "Ixtoc I" oil platform in the Bay of Campeche suffered a blowout leading to a catastrophic explosion, which resulted in a massive oil spill that continued for nine months before the well was finally capped. This was ranked as the largest oil spill in the Gulf of Mexico until the "Deepwater Horizon" oil spill in 2010. On April 20, 2010, the "Deepwater Horizon" oil platform, located in the Mississippi Canyon about off the Louisiana coast, suffered a catastrophic explosion; it sank a day-and-a-half later. It was in the process of being sealed with cement for temporary abandonment, to
Gulf of Mexico basin subsidence in the central region, as well as heavy sedimentation around the Florida Platform and Northern Gulf of Mexico. While a few intrusive igneous formations found as far south as Mexico City are dated to the Late-Jurassic or Early Cretaceous, the Gulf of Mexico during that time was relatively devoid of igneous activity. It wasn't until the Late Mesozoic that low-volume yet widespread volcanism occurred along the Western and Northwestern margins of the Gulf of Mexico, leaving the Yucatan Peninsula with an extremely alkali volcanic field in the subsurface. The volcanism is believed to have been activated along ancient plate
