Palaeoclimatic inferences from upper Palaeozoic siltstone of the Earp Formation and equivalents, Arizona-New Mexico (USA)

Soreghan, Gerilyn S.; Moses, Andrew M; Soreghan, Michael J.; Hamilton, Michael A.; Fanning, Christopher; Link, Paul K.


The Late Palaeozoic configuration of Pangaea contributed to a palaeoclimatic extreme that was characterized by both icehouse and monsoonal conditions. This study uses sedimentological, geochemical, and provenance data from silty facies of the Earp and equivalent Supai Formations (Arizona, New Mexico) to shed light on atmospheric circulation and glacial-interglacial climate change in westernmost equatorial Pangaea. Five silt-rich facies comprise both loessite and marine and fluvially reworked...[Show more]
