Cretaceous Superplume and the Mississippi Embayment

Cox Randel, University of Memphis

In this abstract for the 2000 Annual Meeting of the Geological Society of America, Cox and Van Arsdale suggest that pronounced uplift of the Mississippi Valley Graben region associated with Bermuda hotspot volcanism may have been a result of an increased hotspot flux during the Cretaceous superplume interval (~120 to 65 Ma).
