“…Lamellae are horizontal bands of accumulated layer silicate clays and iron oxides. They form in sandy soils with outwash or aeolian sand parent materials, and usually form below the solum (Gray et al, 1976; Ahlbrandt and Freyberger, 1980; Larsen and Schuldenrein, 1990; Prusinkiewicz et al, 1998; Rawling, 2000; Holliday and Rawling, 2006). Different scenarios of lamellae formation, however, have been hypothesized by many researchers.…”

Movement of clay particles and other colloids through soil profiles has been investigated extensively during the past few decades. The pathway of movement is generally accepted as being predominantly downward. This study investigated the hypothesis that clay and colloids can move upward by capillarity, and is concomitant with water movement. To test this hypothesis, two experiments were conducted. The first experiment used an empty transparent plastic column standing in a 500‐mL glass beaker and packed with dry sand. A reddish clay suspension was used with a concentration of 24.2 g L−1, a pH of 7.1, and an electrical conductivity (EC) of 0.05 S m−1. The clay suspension was added to the beaker so that it could move upward within the sand column by capillarity. The second transparent plastic column was placed empty in a 500‐mL glass beaker and was packed with a 30‐cm layer of dry sand overlain by a 5‐cm layer of sandy loam, which was then overlain by a 20‐cm layer of dry sand. A water table was established to test the likelihood of clay particles moving upward via capillarity. In each experiment, the movements of the clay‐sized materials were visually tracked using a digital camera. The results of the first experiment showed that clay particles moved 25 cm upward and even accumulated at the surface. Clay particles moved upward in the second experiment and formed some clay bands in the sand layer overlying the sandy loam layer.

“…The occurrence of rust-coloured laminae and layers with accumulated iron compounds in the sands Sd, which must have been related to weathering processes. Laminae of such type, named illuvial bands (Prusinkiewicz et al, 1998), illuvial clay lamellae (Johnson et al, 2008) or lamellae (Rawling, 2000;Holliday & Rawling, 2006;Bockheim & Hartemink, 2013), are commonly found in sandy soils in a variety of environments (especially often in dunes and outwash plains). They can have geological (depositional) or pedologic origin (argilluviation, frost migration), or they may form both by geological and pedological processes (Rawling, 2000).…”

Sedimentological interpretation and stratigraphical position of glacigenic deposits in the Napęków area (Holy Cross Mountains, Poland)

The identification of depositional conditions and stratigraphical position of glacigenic deposits in the Napęków area is important for the genetic and stratigraphical interpretation of Quaternary deposits in the central part of the Holy Cross Mountains, as well as for a revision of the course and extent of Middle Polish (Saalian) glaciations. These deposits comprise a series of diamictons which occur between sandy-gravelly deposits. Based on results of macro- and microscopic sedimentological investigations, analysis of heavy mineral composition, roundness and frosting of quartz grains, as well as OSL dating, this complex must have formed during the Odranian Glaciation (Drenthe, Saalian, MIS 6). Sandy-gravelly deposits are of fluvioglacial and melt-out origin. Diamictons represent subglacial traction till. Their facies diversity is a result of variations in time and space, complex processes of deposition and deformation, responsible for their formation at the base of the active ice sheet. This glacigenic depositional complex was transformed by erosion-denudation and aeolian processes in a periglacial environment during the Vistulian (Weichselian, MIS 5d-2).

“…Even in dunes in which palaeosols are not preserved, bounding surfaces of varying degrees of development have frequently been reported (e.g. Holliday and Rawling, 2006), and the degree to which these might be used to infer landscape stability tested (Leighton et al, 2013a).…”

Modelling palaeosol preservation in aeolian dunes

In some of the world's desert and desert‐marginal areas (e.g. Simpson/Strzelecki, Australia) dunefields preserve well‐developed palaeosols, whereas in other regions with broadly similar climatic regimes and topography (e.g. southwest Kalahari), the dunes are characterized by very poorly developed internal stratigraphy. It has been postulated that dunes such as those in the Kalahari may never have had conditions conducive to soil formation, or that soils once formed but any evidence of palaeosols has been lost due to reworking. This study develops and applies a one‐dimensional numerical model to simulate dune development, soil formation and soil preservation. Variables in the model allowed experimentation on the influence of sediment supply, the time taken for soil to form, and the additional resistance to erosion offered by the soil. Reduced sediment supply plays a vital role in landscape development during periods of initial pedogenesis. Although re‐exhumed palaeosols influence sediment supply, the effect is minimal. Although under almost all parameterized conditions more than half (and up to 80‐90%) of those soils initially formed are lost due to reworking, evidence of their past formation remains in the large majority of profiles, and the dominant factor in controlling the preservation of palaeosols is the frequency of their formation. The implication is that where dunes are found without palaeosols, the most likely (albeit not certain) inference is that they have never formed. Counter‐intuitively, the limited sediment supply means their additional resistance to erosion becomes almost inconsequential to their preservation, at least until the unit approaches complete invulnerability. Short chronostratigraphic hiatuses around palaeosols are normal, and although long gaps can occur, they are extremely infrequent. Where such gaps are observed in field studies, external forcing factors (e.g. climatic or environmental changes) are implied, as they are highly unlikely to result from stochastic net preservation.
