Hyperarid coasts develop under relatively high air humidity and abundant sea salt aerosols,
resulting in physical and chemical weathering processes that distinctly differ from those …

Arid alluvial fan aggradation is highly episodic and fans often comprise active and inactive
sectors. Hence the morphology and texture of fan surfaces are partly determined by …

Sediment grain size and surface area impose critical controls on the rates of chemical
weathering, even in cold-based (ie, polar) glacial systems, where extensive chemical …

Alluvial fans are important depositional landforms that offer valuable records of terrestrial
sedimentation history if their surfaces can be mapped and dated accurately. Unfortunately …

Along the coast of the hyperarid Atacama Desert, late Quaternary alluvial fans emerge from
the Coastal Cordillera to the Pacific Ocean between 20.5° S and 25.5° S. Coastal alluvial …

Despite recent advances in mapping and dating alluvial fans, due to the availability of high-
resolution remote sensing data and Quaternary dating techniques, quantifying surface …

Mapping and dating of arid and semi-arid alluvial fans are of great importance in many
Quaternary studies. Yet the most common mapping method of these features is based on …

A basic tenet of arid region geomorphology is that a decrease in hillslope vegetation density
coupled with increases in monsoonal precipitation after a change to a warmer and drier …

Under hyperarid climate conditions, pedogenesis is driven by the atmospheric deposition
and subsequent accumulation of easily to moderately soluble salts forming extreme types of …

The ability of field-based reflectance spectroscopy to resolve the relative proportions of Fe-
oxides and clays in soils was used to map the composition, relative age and distribution of …
