The contribution of aeolian material to an Aridisol from southern Jordan as revealed by mineralogical analysis

Pavements and Stone Mantles

“…Pavements develop where surfaces are stable, i.e. are not subject to significant water erosion (Peel, 1968;Cooke, 1970;Ugolini et al, 2008;Adelsberger and Smith, 2009;Matmon et al, 2009). Associated with the stability of the surface are low slope angles.…”

“…Associated with the stability of the surface are low slope angles. Pavements in Jordan, for example, have developed on a 1 % slope (Ugolini et al, 2008). Although the relationship is not yet well studied, it appears that elevation limits pavement formation, as a result of altitudinally related increases in rainfall and disruptive vegetation cover (Quade, 2001;Marchetti and Cerling, 2005).…”

“…Not all pavement surfaces are shattered by salt. In Jordan, relatively young pavements of low soil salinity lacked salt-shattered clasts, although salts increased clast porosity, allowing calcite to infill voids (Ugolini et al, 2008). Although salt weathering is often associated with an increase in angularity of the particles, the reverse may occur.…”

Desert Soils

“…Weathered rock debris is thus kept exposed and continually rides to the top of the accumulating soil materials, being itself too large to be washed into soil crevices. Thus, far from signifying wind erosion, desert stone mantles may reflect quite the opposite, a local accumulation of significant amounts of material; the soils may thus deepen with time in a process that has been termed 'cumulic pedogensis ' (McFadden et al, 1998;Gustavson and Holliday, 1999;Ugolini et al, 2008). Soil development through time as stone pavements and pavement of poorly sorted stones resulting in very high areal coverage and little exposed fine soil material; (c) view across arid desert pavement to residual hills in the distance.…”

Heavy-mineral derived provenance study of Quaternary sediments of the Mazovian Lowland, Central Poland

“…Indeed, their compilation can be tested towards the applicability in the numerous sedimentary environments, such as coastal (Dill et al 2012;Järvelill et al 2015), marine (Derkachev, Nikolaeva 2013), tsunami (Jagodziński et al 2012), fluvial (Guedes et al 2011;Nascimento et al 2015;Weckwerth et al 2013), aeolian (Hamdan et al 2015;KasperZubillaga, Zolezzi-Ruiz 2007;Kilibarda, Blockland, 2011;Ugolini et al 2008), or glacial settings (Mahaney et al 2011), where the HM proxies are commonly used. Consequently, this correlates with the Polish HM research, of which numerous approaches and applications have been widely tested in the peculiar sedimentary settings in different regions of Poland (Ludwikowska-Kędzia 2013; Marcinkowski, Mycielska-Dowgiałło 2013;Pisarska-Jamroży et al 2015;Wachecka-Kotkowska, Ludwikowska-Kędzia 2013;Woronko et al 2013).…”
