“…This zone of mixing across the lower sections of SU2a also corresponds to a zone of recent insect burrows into the exposed erosion face (Figure 7). As such, it is possible that palaeobioturbation may have disaggregated, dispersed, and over-printed depositional lamellae that were once present (Johnson et al 2008). It is unlikely that burrowing insect activity contributed to sediment grain-size patterns noted above, as ants and termites tend to move fine sediments upwards and not downwards (McBrearty 1990;Van Nest 2002).…”

Claims for a human presence in Australia beyond 60,000 years ago must have a strong evidence base associated with rigorous methodology and intense scrutiny. In this light we present excavation results for Charcoal and Burnt Stone Feature #1 (CBS1) located within coastal dune sediments at Moyjil (Point Ritchie), Warrnambool, that independent geomorphic and OSL dating indicates is of Last Interglacial age (~120,000 years ago). While on plausibility grounds the cultural status of a feature of such great antiquity in Australia is unlikely, a cultural origin for CBS1 is less easily dismissed if assessed with an age-independent methodology. A broad range of macroscale discrimination criteria has been used to assess whether CBS1 is either a cultural hearth or a natural feature such as a burnt tree stump. On balance, evidence marginally supports a cultural origin over a natural origin. However, the absence of associated stone artefacts and faunal remains and the presence of burnt root wood precludes definitive statements on the cultural status of the feature. Our case study is methodologically instructivein terms of the potential complexities and issues of equifinality involved in the archaeological identification of ancient hearths.

“…Úgy a magyar, mint a külhoni szakirodalomban a kovárványnak, ill. a "wetting front"-hoz tartozó jelenségnek helyet adó közege az eolikus, ill. fluvioeolikus homokakkumuláció; esetenként a dominánsan alleuritos szemcseösszetételű talajszelvényekben is megjelenik (JOHNSON et al 2008, KEMP et al, 1989. Hasonló, de litifikált betelepülések követhetők a földtani múlt számos, eredetileg fluvioeolikus homokkő-szelvényeiben, mint pl.…”

Kovárványcsíkok képződése a Nyírség homoktalajában

A Nyírség és Románia északnyugati határvidékének jellegzetes képződménye a helyenként 10 m magasságot is elérő buckákba rendeződő eolikus homok. Itt jelennek meg a kovárványként leírt, több tíz cm vastagságú, vöröses barna színű, lencsés vagy szabálytalan alakú betelepülések, természetes és főleg mesterséges feltárásokban, útbevágásokban.Mivel az eolikus homok jelenleg és feltételezhetően a (földtani) múltban is talajfunkcióval rendelkezett, indokoltnak látszik e betelepülések vizsgálata nem csak egy földtani profilú (külföldi) szakfolyóiratban publikált (KUTI et al. 2017) ásvány-kőzettani és szedimentológiai vonatkozásban, de talajtani szempontokat is figyelembe véve. Ezért tartjuk indokoltnak, hogy az általunk végzett kutatások eredményei magyar nyelven is elérhetők legyenek, főleg a talajképződés szemszögéből nézve.

“…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).
