The authors' observations at the Mimbral locality support the hypothesis of a K-T impact on nearby Yucatán, Mexico, and interpret this clastic unit as the deposit of a megawave or tsunami produced by an extraterrestrial impact. The hypothesis of Cretaceous-Tertiary (K-T) boundary impact on Yucatán, Mexico, predicts that nearby …

Plate tectonics – Historical Geology

As far as their size goes, the plates can be large or small. The largest plates are the Eurasian Plate and the Pacific Plate. The smallest is harder to define. The Juan de Fuca Plate is only 250,000 km 2, a relatively tiny slab in the eastern Pacific Ocean, but there are even smaller "microplates" of oceanic lithosphere between the Pacific and …
