Hi all,

Please join us for Benjamin Gaddis' Doctoral Prospectus Defense on Wednesday, April 1st at 2:00 PM (EST).

Title: Paleomagnetic Studies on the Eastern North American Margin During the Mesozoic Era

Name: Benjamin Gaddis
Date: April 1st, 2:00 PM - 4:00 PM
Location: EOAS 5067
Major Professor: Dr. Richard Bono

Summary: The formation and breakup of supercontinent Pangaea is the largest tectonic event of the Phanerozoic Eon. Associated with the rifting stage of this event is the large igneous province, the Central Atlantic Magmatic Province (CAMP), with associated dikes, sills, basalt flows, and intrusives found throughout the North Atlantic periphery. Much research has been done in quantifying the style and timing of CAMP throughout the Eastern North American Margin (ENAM), but questions remain. Using paleomagnetic data, statistical tests will be conducted both on a pair of crosscutting dikes of the Carolinas, and across the whole of ENAM in order to test whether the same time-averaged geomagnetic field has been recorded. In addition, paleomagnetic data from younger volcanics across ENAM will be used to test for post-rift thermal uplift and subsidence as a means to bring the apparent polar wander paths using data from western and eastern North America into concordance. As a whole, these results will contribute to our understanding of the Laurentian response to the breakup of Pangaea as well as to global paleogeography during the Jurassic.


Best,
Adea
