Geologists and other Earth scientists agree in general that the present Gulf of Mexico basin originated in Late Triassic time as the result of rifting within Pangea the rifting was associated with zones of weakness within Pangea including sutures where the Laurentia South American and African plates collided to create it First there was a Late Triassic-Early Jurassic phase of rifting during which rift valleys formed and filled with continental red beds Second as rifting progressed through Early and Middle Jurassic time continental crust was stretched and thinned This thinning created a broad zone of transitional crust which displays modest and uneven thinning with block faulting and a broad zone of uniformly thinned transitional crust which is half the typical 40 kilometer thickness of normal continental crust it was at this time that rifting first created a connection to the Pacific Ocean across central Mexico and later eastward to the Atlantic Ocean This flooded the opening basin to create the Gulf of Mexico as an enclosed marginal sea While the Gulf of Mexico was a restricted basin the subsiding transitional crust was blanketed by the widespread deposition of Louann Salt and associated anhydrite evaporites During the Late Jurassic continued rifting widened the Gulf of Mexico and progressed to the point that sea-floor spreading and formation of oceanic crust occurred at this point sufficient circulation with the Atlantic Ocean was established that the deposition of Louann Salt ceased. Seafloor spreading stopped at the end of Jurassic time about 145-150 million years ago, Soviet partisans hanged by the German army the Russian Academy of Sciences reported in 1995 civilian victims in the Soviet Union at German hands totalled 13.7 million dead twenty percent of the 68 million persons in the occupied Soviet Union, 6.2 Republic of Texas Microplastics within semi-enclosed seas like the Gulf have been reported in high concentrations and the Gulf's first such study estimated concentrations that rival the highest globally reported!
