Select all of the following orogenic events that were created by volcanic island arcs. Antler Orogeny. Avalon Orogeny. Acadian Orogeny. Taconic Orogeny. (Paleozoic Orogenic Events) In the Permian (end of the Paleozoic), the continents came together forming the super-continent called. Pangaea.The Absaroka sequence was a cratonic sequence that extended from the end of the Mississippian through the Permian periods. It is the unconformity between this sequence and the preceding Kaskaskia that divides the Carboniferous into the Mississippian and Pennsylvanian periods in North America.The cratonic lithosphere then becomes viscously strong after a period of cooling, which then provides the necessary viscosity required for stabilization and longevity (Lenardic and Moresi, 1999).

The transgressive phase of each sequence is generally _____ preserved, whereas the regressive phase is marked by _____ .craton (shield) (adj. cratonic) Area of the Earth 's crust, invariably part of a continent, which is no longer affected by orogenic activity.

It is now possible to restate the concept and to define more explicitly the sequences delimited by interregional unconformities in the continental interior of North America. The sedimentary record of the North American craton from late Precambrian to present is characterized by six ...The Saulk sequence is the first cratonic sequence exposed at the bottom of the Grand Canyon.
