The dust cycle facilitates the exchange of particles among Earth's major systems, enabling
dust to traverse ecosystems, cross geographic boundaries, and even move uphill against …

The study of aeolian geomorphological systems over the last half century has advanced
along several important fronts, supported by developments in technologies and analytic …

Untitled Page 1 Page 2 GEOMORPHOLOGY OF DESERT DUNES Sand dunes cover up to a
quarter of many desert regions. Determining the factors that determine their shape, size and …

Based on four decades of research by Professor Andrew Goudie, this volume provides a
state-of-the-art synthesis of our understanding of desert geomorphology. It presents a truly …

The timing and mode of deposition for Martian regolith breccia Northwest Africa (NWA) 7034
were determined by combining petrography, shape analysis, and thermochronology. NWA …

River-bed sediments display two universal downstream trends: fining, in which particle size
decreases; and rounding, where pebble shapes evolve toward ellipsoids. Rounding is …

Wind‐blown sand and dust models depend sensitively on the threshold wind stress.
However, laboratory and numerical experiments suggest the coexistence of distinct fluid and …

Juvenile pyroclasts, especially in the ash size range, provide important information on
primary fragmentation processes, ie, initial explosive magma fragmentation, and on the state …

The discovery of remarkably rounded pebbles by the rover Curiosity, within an exhumed
alluvial fan complex in Gale Crater, presents some of the most compelling evidence yet for …

Laboratory studies of ripples and dunes show robust relations between bedform geometry
and both fluid flow conditions and grain size. These empirical relations are derived at …
