“…Next, the sample was kept to be drained free on a sandy substrate to reach a constant weight without evaporation; afterwards it was scanned on a tomograph for 2-3 h. Before the tomography, the sample was sealed with a polyethylene film to exclude water evaporation during shooting and structure shrinkage deformation caused by evaporation. The shooting parameters were chosen proceeding from the operation protocols for similar soil samples, analyzed by tomography earlier [20,25,32,44].…”

Analysis of Tomographic Images of the Soil Pore Space Structure by Integral Geometry Methods

et al. 2021

The technique of numerical analysis of three-dimensional tomographic images of the pore space of soil objects has been used in this paper. It applies methods of integral geometry, topology and morphological analysis. To characterize quantitatively the transformation of the pore space structure, tomographic images of four undisturbed soils were analyzed, i.e., heavy loamy agro-gray soil (Retic Phaeozem), agromineral (Sapric Rheic Mineralic Histosols), and hypnum (brown moss Sapric Rheic Histosols) peat soils in dry and wet conditions. For samples of the subplow horizon in agro-gray soil, a decrease in both Betty numbers was observed on wetting, where the zero number (b0) stands for the amount of topologically simple closed pores, and the first number (b1) indicates a decrease in pore connectivity, which varies in a narrower range of pore sizes as compared to b0. When a sample of agromineral peat soil is moistened, the Euler–Poincaré characteristic is negative in the pore range of 0.1–0.16 mm, which points to the predominating complicated branched structure of the pore space and high pore connectivity. When hypnum moss is saturated, a lot of tunnel pores get narrower (“collapse”), and the connectivity decreases due to the structural specifics of long-stemmed plant residues. The number of pores and connections between them in peat soils is an order of magnitude higher than those in the subplow horizon A of the agro-gray soil. The provided quantitative changes in the considered parameters of tomographic images of the soil pore space confirm the possibility of applying them for estimating the transformation of the pore space in soils.

“…Pore space was studied by computed tomography to describe the pore distribution and connectivity. The porosity may contain a significant element of soil memory in the shape and orientation of pores (Romanis et al, 2021) and preserves the original forms for a long time (López-Prat et al, 2021). Tomographic scanning of soil samples was performed using a Bruker SkyScan 1172 G 3D X-ray scanner.…”

Paleosols interbedded with pyroclastic deposits have been proven to be an important paleoenvironmental proxy for the late Quaternary in Central Mexico. We studied a key upland section and several profiles on the slopes and lowlands of the Tlaxcala Block, assuming that the topographic variability of the soil-sedimentary mantle contains the complete record of the landscape history. The upland section included three paleosols separated by tepetates (compact volcanic pedosediments) and reflected a general trend of environmental evolution during the last 40 ka. Particle-size distribution, bulk chemical composition, magnetic characteristics, computed tomography, and micromorphological observations demonstrated a strong seasonality of paleoclimate at the end of MIS3, followed by cool wet conditions during the last glacial maximum, subsequent warming at the beginning of the Holocene, and drying during the last 3 ka. It was shown that tepetates had well-developed pedogenetic features that contribute to the paleosol record. The studied slope and lowland profiles reflected the main phases of geomorphic activity in the terminal Pleistocene and the early Holocene. These phases are linked to paleoclimate fluctuations in Central Mexico at the end of the last glaciation.

“…When accompanying archeological materials, these can deliver high‐resolution, local, conterminous paleoecological reconstructions that provide important context to anthropogenic subsistence. When archeological materials are not present however, they are often correlated with other regional records that document landscape change and occupation history over time (Romanis et al ., 2021) and space (Nerudová et al ., 2021). At a larger scale still, loess records have been used to inform diachronic changes in paleodemography and typotechnological trends born out primarily in the lithic record by providing an important record of broad‐scale regional and temporal environmental change (Morgan et al ., 2011; Schmidt and Zimmermann, 2019) even if analytical units are still precarious (Reynolds, 2020).…”

Loess is a main archive of Pleistocene landscapes and environments and therefore has an important connection to the preservation and interpretation of Paleolithic sites. In Europe, anthropogenic sites have been found in loess because of past local occupation. At one extreme, sites are well preserved with minimal disturbance often accompanied by embedded proxies to estimate ecological parameters. On the other hand, loess deposits have undergone post‐depositional alterations such as weathering, pedogenesis or bioturbation due to changing environmental conditions or other disturbances that obscure anthropogenic sites. We outline the current state of research and connections between Paleolithic archeology and loess research while introducing a series of subsequent regional case studies as part of a special issue. We also make recommendations for future work to incorporate a wider variety of methods to create more robust inferences on hominin and environmental evolution and their connections.
