Identifying eolian dust in the geological record [PDF]
Earth-Science Reviews, 2020 Recognition of terrestrial dust in geological records is essential for reconstructing paleoenvironments and quantifying dust fluxes in the past. However, in contrast to eolian sands, silt-sized dust is difficult to recognize in pre-Quaternary records due to a lack of macroscopic features indicating eolian transport and mixing with alluvial sediments ...

Eolian dust input to the Subarctic North Pacific [PDF]
Earth and Planetary Science Letters, 2014 Eolian dust is a significant source of iron and other nutrients that are essential for the health of marine ecosystems and potentially a controlling factor of the high nutrient-low chlorophyll status of the Subarctic North Pacific. We map the spatial distribution of dust input using three different geochemical tracers of eolian dust, 4He, 232Th and ...

Martian Eolian Dust Probed by ChemCam [PDF]
Geophysical Research Letters, 2018 AbstractThe ubiquitous eolian dust on Mars plays important roles in the current sedimentary and atmospheric processes of the planet. The ChemCam instrument retrieves a consistent eolian dust composition at the submillimeter scale from every first laser shot on Mars targets.

Earth and Planetary Science Letters, 2019 As one of the largest dust sources on the Earth's surface, dryland in Central Asia gives rise to thick eolian deposits over East Asia (e.g., the Chinese Loess Plateau, CLP) and significantly influences the regional hydrochemistry in the downwind drainage

Studies on Eolian Dust in Greece
Geografiska Annaler: Series A, Physical Geography, 1989The origin of the Mediterranian terra rossa soils is disputed. The current opinion is that these soils are a product of limestone weathering. However, some scientists believe that terra rossa is an eolian deposit originating from North Africa. Our project was inspired by this discussion and deals with eolian deposits and dust storms in Greece ...

Dust storms and eolian deposits in the Mediterranean area
Gff, 1986Abstract Investigations in Crete and southern Peloponnese show relatively numerous deposits of eolian character. Two types of possible eolian deposits have been observed; pale yellow, 3–5 m thick deposits in Crete situated up to an altitude of about 600 m above sea level, and brownish red, slightly thinner (about 0.5–4 m) deposits which occur at all ...

Soil Science and Plant Nutrition, 1987
Physical, chemical, and mineralogical properties of aerosols and air fall sediments collected in Hachimantai, Osaka, Yashiro, Izumo, Oita, and Sasebo from 1981 to 1984 were studied and were compared with those of loess and loess soils in China and Korea. The texture of most aerosols and air fall sediments ranged from silty clay to clay loam.

Soil abrasion and eolian dust production: Implications for iron partitioning and solubility
Geochemistry, Geophysics, Geosystems, 2006 Eolian dust is a source of iron for phytoplankton in many ocean areas, and there are complex pathways of atmospheric processing from soil to ocean. Overlooked parts of the pathways are the impact of large (>10 孩 grains (including a role as proxies for ...
