“…The sulfate had a simple chemical structure and consisted of tetrahedral sulfate groups whose O atoms were coordinated with interstitial cations [49]. A very good correlation can be observed between our measured data and the literature [48][49][50][51]: the four modes of vibration of sulfate tetrahedral oxyanion occur at 992-993.2 (ν 1-symmetric stretching), 451-466.6 (ν 2-symmetric bending), 1102.1-1178 (ν 3-antisymmetric stretching), and 620-647.2 (ν 4-antisymmetric bending). For our samples, the Raman spectra corresponded to Na 2 SO 4 , with spectral signature features showing a strong peak at 992 cm −1 for ν 1 , which in turn corresponded to the symmetric stretches of the S-O 4 tetrahedron.…”

Risk of Salinization in the Agricultural Soils of Semi-Arid Regions: A Case Study from Moldavian Plain (NE Romania)

In the present study, the salinization trends of different soil types from a small hydrographic basin situated in NE Romania (Roșior basin) are investigated. The climatic conditions are favorable for long dry summers and intensive evaporation. The soils are developed on immature evolved clay sediments, as revealed by geochemical analysis. The salinity varies among soil types, attaining maximum values for Solonetz with total dissolved salts (TDS) between 1165.75 to 1881.25 mg/L. The aqueous solutions are represented by natural water and soil solution. The hydrogeochemical facies of the natural waters change from HCO3−—Mg2+ in the upper basin to SO42−—Na+ in the middle or lower basin. The soil solution is moderately or strongly salinized and shows anionic variations from HCO3− to SO42- in the studied profiles, whereas Na+ is always the main cation. The concentrations of Na+ and SO42− evolve simultaneously. Raman spectroscopic exploration of the white efflorescences, which occur on topsoil, reveals the presence of thenardite as the dominant phase. The composition of soil solution results from both the ionic exchange and evaporation processes. The nature of soil solution mineralization and summer temperatures are two main factors that interact and promote the thenardite precipitation. The soil salinization induces negative effects on crop nutrition, impacting further the crop yields. The results of this study can be extrapolated to larger areas formed on Sarmatian sedimentary deposits affected by salinization processes.

“…Whilst we acknowledge that historical reports and archaeological evidence about frontier conflict events can never reveal a comprehensive picture and in fact may fail to generate significant new data, we also argue that frontier killings and massacres should not be allowed to "transcend history"and that each and every event should be interrogated subject to the wishes of Aboriginal traditional owners. The research presented in this article is just one aspect of a broader project to interrogate the colonial frontier in SA's Riverland region (see also Burke et al, 2016;Roberts et al, 2018;Roberts et al, 2020b).…”

This article presents the results of historical research, as well as archaeological and geophysical surveys, in order to explore a number of frontier conflict events at Dead Man’s Flat in South Australia (SA). The historical records reveal the cruelty and complexity of the period and expose the concealments, contradictions, euphemistic language, denials and silences that are typical of the Australian frontier. Further disparities are revealed in more recent commemorative efforts. Archaeological investigations in the study area provided an ‘absence of evidence’. Whilst the geophysical survey revealed that there are potential graves located on the flat, no interment was located in the area commemorated by local non- Indigenous community members. The combined results of this multi-method approach uncovered new dissonances, raised new questions and provided new exegeses about the frontier in this region. For traditional owners, the sum of the evidence reveals a history of invasion, killings and massacre, theft, deceit and cover-up – Dead Man’s Flat is, therefore, a place to be approached with deep respect in order to honour the experiences of their ancestors.

Archaeology on the edge: radiocarbon chronologies for Aboriginal cliff-top sites of the Murray River, South Australia

This paper presents new radiocarbon dates for two Aboriginal archaeological complexes situated on the cliff-lines of the Murray River in South Australia (SA); at Pooginook Flat and Tanamee. These dates represent the first age estimates for archaeological sites within the Upper Gorge section of the Murray River. The dates ranged from ca. 11 cal ka to the Late Holocene. The research supports previous evidence which has indicated that sites located along the Murray cliffs preserve much of the oldest evidence of Aboriginal peopling along the Murray River corridor in SA. The new dates also allow us to contribute to discussions concerning broader chronological trends in Aboriginal lifeways within the Murray-Darling Basin (MDB). Specifically, the new ages add some insight into the nature and timing of early Aboriginal occupation along the Murray River corridor in SA and further evidence that the LGM acted as a significant inhibitive factor for intensive occupation of this riverscape. The conservation of these significant and informative cliff-top sites remains precarious, however, and there is an imperative to continue to record and sample the extant sites.
