“…Instead, MnS is likely to occur in brackish environments, enriched in sulfates and sulfides (Eusterhues et al, 2005). The conclusions of Eusterhues et al (2005) are in good accordance with the fact that in the Sa1/2 profile, the highest contents of Mn IV were obtained in brown muds and olive gyttjas, deposited in the brackish water body (Bechtel et al, 2007;Woszczyk et al, 2008). Relatively small contents of reducible manganese (Mn III ) in the Sa1/2 profile can be attributed to pronounced thermodynamic instability of Mn oxides in anoxic sediments (Donahoe and Liu, 1998).…”

“…Mn-enriched calcite, very often reported from aquatic sediments (Tessier et al, 1979;Cundy and Croudace, 1995;Kiratli and Ergin, 1996;Sternbeck and Sohlenius, 1997;Zerbe et al, 1999;Balkis and ÇaÈatay, 2001;Eusterhues et al, 2005;Shen et al, 2007), forms from substitution of Ca 2+ ions in calcite crystals by Mn 2+ , whose ionic radius is similar to that of Ca 2+ (Shen et al, 2007). As observed by Calvert and Pedersen (1993), carbonate-associated Mn precipitates just below the anoxic sediment -oxygenated bottom water interface, and thus indicates oxidising conditions in lakes.…”

“…As a rule, reduced species of Mn substitute Fe 2+ in pyrite, rather than form separate mineral phases. In fact, precipitation of Mn sulfides is hardly ever observed, especially in freshwater lakes, owing to their high solubility in water (Eusterhues et al, 2005). Instead, MnS is likely to occur in brackish environments, enriched in sulfates and sulfides (Eusterhues et al, 2005).…”

“…The association of iron with the oxidisable fraction is typical for this element, which in the presence of H 2 S tends to form insoluble sulfides (Tessier et al, 1979;Kiratli and Ergin, 1996;Clark et al, 1998;Eusterhues et al, 2005). However, complexes of iron with organic substances are also common (TokalioÈlu et al, 2000).…”

This article documents and interprets stratigraphical changes in fractionation of Fe, Mn, Mg, K, Pb, Cu and Zn in the Sa1/2 sediment core from a coastal freshwater lake, Lake Sarbsko (northern Poland). The elements were sequentially extracted from the samples to distinguish five geochemical fractions: exchangeable, acid-extractable, reducible, oxidisable and residual. The analyses revealed substantial variations in geochemical partitioning of the elements and showed no correlation between the fractionation patterns and lithology of the sediments. In the sediments of Lake Sarbsko, iron is mainly bound to sulfides. Potassium occurs in its residual form. Magnesium and zinc are associated with carbonates and aluminosilicates, while copper occurs in compounds with organic matter and sulfides. Lead is found in connection with aluminosilicates and, to a lesser extent, with sulfides and organic matter. Manganese is partitioned between the oxidisable, acid-extractable, and exchangeable fractions. Heavy metals and potassium display the overall tendency to reduce the contents of their residual forms towards the top of the depositional sequence. Fe, Mn, Mg and Zn were found to be the most susceptible to post-sedimentary mobilisation.

On the border between land and water: The environmental conditions of the Neolithic occupation from 4.3 until 1.6 ka BC at Serteya, Western Russia

The paper presents the results of a palaeoecological study of Neolithic archaeological layers from a wetland, multilayer site, Serteya II (Western Russia). It contains, domestic structures, rich organic artefacts, skeletons, and ecofacts preserved within lacustrine deposits that are extremely important on a European scale. We employed a set of specialised palaeoecological analyses and accelerator mass spectrometry radiocarbon dating to identify the principal environmental conditions which attracted Neolithic hunter‐fisher‐gatherer communities from 4300 to 1600 cal. BC. The distinct impact of communities using a nonproductive economy on the ecology of the palaeolake shore zone was recorded. Also, palaeolake water level changes influenced the palaeoeconomic activity of local Neolithic societies, such as gathering of plants (for the medicinal use or serving as dietary components), fishing activities, and possible funeral practices. In addition, the identified phases of high‐water level changes, which were responses to climatic oscillations, were correlated with supraregional climatic events, especially ca. 6.2, 5.9, and 4.2 ka cal. BP. Thus, our results allowed for the reconstruction of environment transformations and conditions of Neolithic communities' activity, as well as for a better understanding of the relationships between local Neolithic communities' way of life and neolithisation processes in Eastern Europe.
