Atmospheric dust flux in northeastern Gondwana during the peak of the late Paleozoic ice age
(2020-10-05)The silicate mineral fraction of shallow marine carbonates archives dust contributions to the Central Persian Terranes along the northeastern margin of Gondwana (∼30°S paleolatitude), enabling reconstruction of atmospheric ... -
Experimental production of dust by replicating aeolian and glacial abrasion
(2023-05-12)Dust is a highly mobile and influential class of sediment. Dust influences the climate, biosphere, and soils, and holds information about Earth’s paleoclimate when preserved in the rock record. In this work we define dust ... -
Giant grains in the Akiyoshi Limestone: A record of atmospheric circulation over the Panthalassic Ocean
(2021)Models indicate that atmospheric transport distances for large windblown particles are limited to tens to perhaps hundreds of km owing to rapid gravitational settling, yet a number of studies of modern–recent sediment have ... -
Report on ICDP Deep Dust workshops: probing continental climate of the late Paleozoic icehouse–greenhouse transition and beyond
(2020-12-01)Chamberlin and Salisbury's assessment of the Permian a century ago captured the essence of the period: it is an interval of extremes yet one sufficiently recent to have affected a biosphere with near-modern complexity. The ...
