“…Shepard's classification system was implemented (Shepard, 1954) to determine the grain‐size group. The textural attributes of sediments, mean (Mz), standard deviation (SD), skewness (Ski), and kurtosis (KG) were also used (Folk & Ward, 1957; Goswami & Ghosh, 2011; Vakalas et al, 2004).…”

Lacustrine environments are considered favorable locations for Neolithic settlements, constituting a reliable year‐round water resource, which contributes to fertile arable land, rich biodiversity, and natural protection. Living by the wetlands, however, is characterized by intensive ecological vulnerabilities, that is, floods and fire events. These recurrent episodes are difficult to trace in the occupation layers since natural processes combined with human activities can form variable mixed microenvironments. Consequently, the direct impact of these events on the biography of the settlement and the decision‐making of its inhabitants is understudied. This paper presents a high‐resolution, microstratigraphic analysis at the Neolithic pile‐dwelling settlement of Dispilio (Kastoria, northern Greece) to trace past ecological threats and unravel the resilience strategies of the lake‐dwellers against the continuously altered microenvironments. By correlating the results with regional environmental and cultural events, this paper questions the role of environmental changes as triggers for cultural modifications and considers a wide range of strategies for coping with wetland hazards.

“…The area has experienced polycyclic evolution (Chorley, Beckinsale, & Antany, 1973). The terrain has experienced the Proterozoic ductile shearing (Naik, K, & Wasthi, 2003) and the related deformation (Goswami & Ghosh, 2011). In the foothill zone, two perennial springs are observed (Fig.…”

Shushunia hill lies in a transitional zone of the South Singbhum Mobile Craton and northern Gondwana formation. The Shushunia hill appears like a porcupine peak and it has structural similarity to the Eastern Ghat. The Shushunia hill zone is an example of a contact spring. In the foothill zone, two perennial springs are observed. The study purely deals with its aquifer and water quality. Based on the present rock strata and the nature of the contact aquifer, its early condition has been assumed. The discharge of the confined aquifers occurs by leakage. The water temperature depicts the springs are not of geothermal origin. Shushunia's aquifer is the shallow flow system water table and it is the subdued replica of surface topography. The comparatively high discharge rate during post-monsoon indicates the fractured conduit-water seepage towards the aquifer. Moreover, twin-contact aquifers do not yield water uniformly. The perennial aquifer may act as a municipal water supply source for drinking purposes in the future.

“…Hence, the analysis of the physical properties of the grains, such as size and density, may help in reconstructing the kinetic energy of the depositional environment (Sun et al ., 2002; Papanicolaou et al ., 2003; Rodríguez‐López et al ., 2006). The textural grain‐size characterization of sediments based on the calculation of mean, sorting, skewness and kurtosis of the grain‐size distributions is an established tool to analyze the fabric of sedimentary rocks and to understand the physics behind the depositional processes (Edwards, 2001; Martin, 2001; Boggs, 2009; Goswami & Ghosh, 2011). These statistical parameters have been widely used to distinguish different fluid‐dynamic conditions, transport, accumulation and potential remobilization processes (Folk, 1954; Folk & Ward, 1957; Mason & Folk, 1958; Friedman, 1961; Visher, 1969; Valia & Cameron, 1977; Ashley, 1978; Bagnold & Barndoff‐Nielsen, 1980; McLaren & Bowles, 1985; Sutherland & Lee, 1994; Sun et al ., 2002; Martins, 2003; Qiang et al ., 2007, 2010; Weltje & Prins, 2007; Vandenberghe, 2013).…”

Lost in the wind: An integrated approach for the recognition of mixed clastic–carbonate continental aeolianites

et al. 2022

Aeolianites with a mixed clastic and carbonate detrital mineralogy are typical deposits of tropical coastal desert environments. These deposits are genetically related to transgressive–regressive cycles, with the shallow‐marine carbonate detrital component being deflated from the exposed seafloor during episodes of glacial sea‐level lowstands, transported and later accumulated onto more continental areas. A detailed investigation of the granulometric and petrographic properties of the Late Pleistocene to Holocene Ghayathi Formation in the United Arab Emirates provides a comprehensive numerical dataset that reveals the complex spatio‐temporal depositional and diagenetic evolution of a mixed siliciclastic–carbonate continental aeolianite. Fifty‐one thin sections and forty‐four rock samples of three sedimentary units (Madinat‐Zayed, Ghayathi and Fuwayrit formations) from the United Arab Emirates were analyzed for their grain‐size distribution, mineralogy and the bulk stable‐carbon and oxygen isotopic composition. Sorting, skewness and kurtosis of the grain‐size distributions provide evidence for a divergent aerodynamic behaviour between the carbonate and siliciclastic particles. The different grain‐size distributions between the inland and coastal sections of the Ghayathi Formation indicate that continental mixed clastic−carbonate aeolianites are affected by density‐driven selective transport and consequent traction sorting due to the nature of carbonate detritus. The transport decoupling of the different detrital components resulted in a ‘continental sorting’ effect, with the inland sections yielding layers characterized by a better sorted detritus than the coastal areas. All detritus originally composed of aragonite has been removed by dissolution during early meteoric diagenesis, with its shapes frequently preserved by micritic envelopes. The bulk stable‐isotope composition of the carbonate fraction reflects a decreasing degree of meteoric cementation from coastal to inland areas. The high complexity of the lateral and vertical distribution of the sedimentary, diagenetic and isotopic properties of continental mixed aeolianites, such as the Ghayathi Formation, highlights the problem of recognizing such deposits in the pre‐Quaternary sedimentary record.
