Dust and Loess in Equatorial Pangaea

Dust and loess (continental, wind-blown silt) are well known as both archives of climate and agents 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., and elsewhere (e.g. France) along the paleoequator. Dust was sourced from regions that included the equatorial Central Pangaean Mountains. Notably, the voluminous atmospheric dust stimulated productivity in the marine and terrestrial biosphere, thus affecting carbon cycling and organic-carbon burial. 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.
