Organic matter in eolian dusts over the Atlantic Ocean
Marine Chemistry, 1977Abstract The elemental and mineralogical composition and the microfossil and detritus content of particulate fallout from the lower troposphere over the Atlantic Ocean have been extensively documented in earlier work, and it was possible to ascribe terrigenous source areas to such fallout.

Eolian dust in the coastal desert of the sudan: Aggregates cemented by evaporites
Geo-Marine Letters, 1984Eolian dusts collected after dust storms contain aggregates that are cemented by evaporitic salts, mainly halite. They vary in shape, fabrics, and surface roughness. Aggregation changes grainshape, density and size distribution of dust particles (i.e., characteristics determining erosion and transport); on deposition in the sea, cements dissolve and ...

Eolian dust deposition on the Giara di Gesturi basalt plateau, Sardinia
Earth Surface Processes and Landforms, 1984AbstractMineralogical study of samples from depression fills on an isolated basalt plateau in Central Sardinia showed that, although the basalt is free of quartz and mica, fair amounts of these minerals occur in the finer fractions. Results from X‐ray analyses of silt fractions and morphoscopical analyses of sand fractions indicate that the bulk of the

Particle-size fractionation of eolian dusts during transport and sampling
Marine Geology, 1976Abstract In recent years considerable attention has been given to eolian dusts and their contribution to deep-sea sediments. However, particle-size fractionation during transport and deposition can lead to considerable modification of these dusts, so that misinterpretation can occur.

Eolian dust in the coastal desert of the Sudan: aggregates cemented by evaporites
Journal of African Earth Sciences (1983), 1985Abstract Eolian dusts collected after dustorms locally called “haboob” contain aggregates which are cemented by evaporitic salts, mainly halite, and which vary in shape, fabrics and surface roughness. Aggregation changes grain shape, density and size-distribution of dust particles, i.e. characteristics determining erosion and transport.

Asian Dust, Eolian Iron and Black Carbon—Connections to Climate Changes
2014This chapter focuses on the aridification of the Asian interior during the Late Cenozoic, with an emphasis on modern dust and black carbon, and examines global iron connections which originate from dust derived from the arid interior of Asia. The modern formation of Asian dust, the connection of black carbon, paleofires and climate change, and ...

Effect of rock fragment eccentricity on eolian deposition of atmospheric dust
CATENA, 1994Abstract The effect of rock fragment eccentricity on the deposition of airborne dust was examined in a wind tunnel. Eccentricity was defined as the ratioa/b, wherea is the longest andb the intermediate axis of the rock fragments. The effect of eccentricity on the deposition of dust on the pebbles, on the deposition of dust between and underneath the ...
