Abstract

A sequence stratigraphic framework is used to document a major extinction and migration episode that occurred in the Middle and Late Ordovician of North America. This event is characterized in eastern North America by coordinated changes in faunal assemblages, carbonate lithologies, siliciclastic influx, and phosphatization. These changes are ascribed to a regional paleoceanographic event brought on by thrust-driven flexural subsidence and sea-level fluctuations that lowered water temperature and increased turbidity and nutrient input. -from Authors
