#SaltSaturday The geology offshore Mexico is fascinating. Let's change the perspective and look at the margin from the North . Salt was deposited in the middle Jurassic during the opening of the Gulf of Mexico. A passive margin was established in the Cretaceous followed by

a major orogenic event leading to uplift of Sierra Madre Oriental in the Paleocene to Oligocene. During the Laramide orogeny, Salina del Istmo Basin behaved as a foredeep associated with this major mountain building event. A second regional event occurred in the Miocene, related

to the subduction of the Cocos plate south of Mexico, leading to uplift of Sierra Madre de Chiapas and impacting the salt-dominated sedimentary basin with contraction propagating basinward. The present-day structural styles in the basin are complex and breathtaking (tbc)
