Dust/loess is well known as both an archive of climate and agent of climate change for Earth’s recent record. But dust deposits are increasingly recognized in Earth’s deep-time record, especially from the Permian. Thick dust deposits occur in the western-midcontinent U.S. Data indicate that dust deposition pulsed on a glacial-interglacial timescale, and was sourced from regions that included the equatorial Central Pangaean Mountains. Notably, the voluminous atmospheric dust stimulated productivity in the marine and terrestrial biosphere. Recent recognition of extraordinarily thick dust deposits in the Permian Anadarko basin have spawned efforts for an international research coring campaign to recover the longest continuous record of climate ever attempted, with the potential for abundant auxiliary science. 

 

Bio—

Dr. Lynn Soreghan is the Director and Eberly Family Chair, and David Boren Professor in the School of Geosciences, University of Oklahoma. Lynn uses sediments to interpret Earth’s “deep-time” climate, with interests in ancient glaciations, atmospheric dust, and weathering. She earned her B.S. (Geology, 1986) at UCLA, and her PhD (Geology, 1992) at the University of Arizona, and subsequently worked at Amoco Production Company before joining (in 1996) the faculty of the University of Oklahoma.
