“…Important is the presence of many phytoliths and some volcanic glass fragments in the coarse fraction of the bleached horizons. Especially the open porphyric c/f related distribution pattern of the Bw horizons, with the strongly expressed striated b-fabric, the disorthic, nearly opaque nodules and the stress deformed clay coatings (striated orientation, locally kink-band fabric) correspond to a typical vertic material as described by Kovda and Mermut (2010). An important pedofeature of these soils are the iron oxide nodules; diffuse and moderately impregnated nodules ( Fig.…”

“…Microscopic fabrics and structures indicative of mixing due to bioturbation, human and animal trampling or pedoturbation can be observed in thin section (Banerjea et al 2013;Kooistra and Pulleman 2010;Kovda and Mermut 2010;Miller et al 2009). Gravitational settling, seasonal down profile seepage and redistribution of water can cause downward movement of fine sedimentary particles, which can also be observed using micromorphology.…”

Rockshelters contain some of the most important archives of human activity in Australia but most research has focused on artifacts and cultural context. This study explores geomorphological and geoarchaeological approaches for understanding a sandstone rockshelter in interior northern Australia: Gledswood Shelter 1. At this site, magnetic susceptibility and micromorphology techniques were integrated with bulk sedimentology, soil chemistry and geochronology to better understand the record of human impact and site formation processes. The micromorphology studies indicate that primary depositional fabrics, such as graded bedding or laminations, are absent, and sediment structural development is low throughout the entire sequence, with most samples exhibiting a high degree of post-depositional mixing. The sediment magnetic susceptibility analysis reveals magnetic changes coinciding with human occupation, a result of anthropogenic burning. Specifically we highlight that combustion features are prevalent in this sandstone shelter and provide critical insights into the human usage of the shelter.

“…Sedimentary characteristics of semi-permanent water saturation include a prismatic structure, slickensides and redoximorphic features (mottling, Fe-Mn coatings, hypocoatings and nodules). These are more frequent in the deeper units (3a and 3b) due to their proximity to the groundwater table (Kovda and Mermut 2010;Lindbo et al 2010). The higher organic carbon content in Unit 3a may relate to its more permanent saturation conditions relative to the other sedimentary units.…”

“…Calcite nodules are disorthic (i.e., with sharp boundaries) and rounded (Fig. 7a), features that are common in vertisols, resulting from argilliturbation (Blokhuis et al 1969;Kovda and Mermut 2010). They are commonly iron-impregnated (except for sparry domains).…”

“…The shrinking and swelling of the clay component results in argilliturbation, reflected in the formation of slickensides, contributing to the formation of sharp boundaries and roundness of calcite nodules (Blokhuis et al 1969;Kovda and Mermut 2010). Argilliturbation can lead to an upward movement of the nodules in the profile (Blokhuis et al 1969;Wood and Johnson 1978).…”

Geoarchaeological Investigation of Site Formation and Depositional Environments at the Middle Palaeolithic Open-Air Site of ‘Ein Qashish, Israel

'Ein Qashish is a Middle Palaeolithic open-air site in the southern Levant, encompassing an excavated area of several hundred square meters and a 4.5-m thick stratigraphic section. Its placement within a fluvial system, combined with the presence of Neanderthal skeletal remains and diverse material culture finds, presents possibilities J Paleo Arch (2018) Palaeolithic. The aim of this study is to investigate the depositional and post-depositional processes at 'Ein Qashish, based on the stratigraphic section exposed in the 2013 excavation season. We employed field observations, sedimentology, micromorphology, mineralogy, elemental and isotopic analyses. Our results indicate that the sedimentary sequence, including four archaeological occupation levels, accumulated in a generally low-energy alluvial environment with evidence for syn-depositional localised seasonal water bodies. On-going post-depositional processes related to wetting and drying cycles include shrink-swell and calcite and gypsum pedofeatures. Bone mineral is relatively well preserved. The data suggest limited fluvial and argilliturbation reworking of artefacts, indicating that spatial patterning of lithic and bone assemblages is rather well preserved in some areas. The current analyses do not indicate the presence of combustion features or fire-related residues at the site, although burned lithics occur in low frequencies. The absence of combustion features in the large excavated area and deep stratigraphy contrasts with patterns observed in Middle Palaeolithic cave occupations in the region, adding nuance to a dataset that will enable a better understanding of human activities under sheltered and open-air conditions.
