... chemical tracers of exogenous dust and aerosol additions to the soils. The removal of major elements and REEs is impossible in the present climate (one of salt and dust accumulation), revealing that for a significant period following the deposition of the alluvium, soils were exposed to rainfall, chemical...

... wind composition has variability: during impulsive coronal mass ejections the relative concentration of heavy ions (He ++ , O 7+ , etc.) can increase to > 20%. Copyright © 2023 by the Mineralogical Society of America 2023 Mineralogical Society of America The topics of lofted dust...

..., Appalachian sources, and paleogeographic setting in the subtropical arid belt far-removed from contemporaneous deltaic feeder systems are most consistent with eolian transport of dust lofted from subaerial delta plains of the greater Appalachian orogen and incorporated into subaqueous depositional systems...

... also reveal spatial variability in sediment provenance between the western and central parts of the Chinese Loess Plateau, which is potentially affected by dust transport from westerly/northwesterly winds. Our integrated data set provides diagnostic constraints on the dust source, provenance...

...Alison M. F. Lee; Airi Maruyama; Song Lu; Youhei Yamashita; Tomohisa Irino Abstract Japan sea sediments consist of various detrital materials of eolian and riverine origin. Understanding the provenance of eolian dust is vital for reconstructing the variability of wind patterns and monsoons...

... Ocean. Past changes in the strength and position of this wind belt are poorly resolved, particularly across the Pleistocene-Holocene transition, a time period associated with fluctuations in atmospheric temperatures and CO 2 levels. We used dust geochemistry, particle size measurements...

...M.J. Pankhurst; C.J. Stevenson; B.C. Coldwell Abstract Meteorite impacts load the atmosphere with dust and cover the Earth's surface with debris. They have long been debated as a trigger of mass extinctions throughout Earth history. Impact winters generally last <10 0 years, whereas ejecta...

...Mark R. Sweeney; Steven L. Forman; Eric V. McDonald Abstract Recent research on dust emissions from eolian dunes seeks to improve regional and global emissions estimates and knowledge of dust sources, particularly with a changing climate. Dust emissions from dune fields can be more accurately...

... and by quantifying the cohesion of layered deposits in the Arabia Terra region. We demonstrate that variations in dust cover associated with relative erodibility and eolian abrasion can be inconspicuous controls on apparent thermal inertia. We ultimately find that these deposits are not as cohesive as would...

... environments is better characterized as “hydrohematite”. Moreover, we speculate that the spherical hematitic “blueberries” on Mars ( Squyres et al., 2004 ) and perhaps the Hm in Martian dust ( Christensen et al., 2001 ; Fraeman et al., 2013 ) incorporate hydroxyl, and thus serve as an unappreciated reservoir...

Furthermore, nonuniformity in CLP Quaternary sediment provenance raises questions about the validity of using paleoclimate information archived in the CLP to make sweeping regional interpretations. Loess deposits provide...
