Article Reference Spring Water Geochemistry: A Geothermal Exploration Tool in the Rhenohercynian Fold-and-Thrust Belt in Belgium
Spring water geochemistry is applied here to evaluate the geothermal potential in Rhenohercynian fold and thrust belt around the deepest borehole in Belgium (Havelange borehole:5648 m MD). Fifty springs and (few) wells around Havelange borehole were chosen according to a multicriteria approach including the hydrothermal source of “Chaudfontaine” (T =~ 36 °C) taken as a reference for the area. The waters sampled, except Chaudfontaine present an in-situ T range of 3.66–14.04 °C (mean 9.83 °C) and a TDS (dry residue) salinity range of 46–498 mg/L. The processing methods applied to the results are: hierarchical clustering, Piper and Stiff diagrams, TIS, heat map, boxplots, and geothermometry. Seven clusters are found and allow us to define three main water types. The first type, locally called “pouhon”, is rich in Fe and Mn. The second type contains an interesting concentration of the geothermal indicators: Li, Sr, Rb. Chaudfontaine and Moressée (=~5 km East from the borehole) belong to this group. This last locality is identified as a geothermal target for further investigations. The third group represents superficial waters with frequently high NO3 concentration. The application of conventional geothermometers in this context indicates very different reservoir temperatures. The field of applications of these geothermometers need to be review in these geological conditions.

Article Reference Stable isotope evidence for late medieval (14th-15th C) origins of the eastern Baltic cod (Gadus morhua) fishery
Although recent historical ecology studies have extended quantitative knowledge of eastern Baltic cod (Gadus morhua)exploitation back as far as the 16th century, the historical origin of the modern fishery remains obscure. Widespreadarchaeological evidence for cod consumption around the eastern Baltic littoral emerges around the 13th century, threecenturies before systematic documentation, but it is not clear whether this represents (1) development of a substantialeastern Baltic cod fishery, or (2) large-scale importation of preserved cod from elsewhere. To distinguish between thesehypotheses we use stable carbon and nitrogen isotope analysis to determine likely catch regions of 74 cod vertebrae andcleithra from 19 Baltic archaeological sites dated from the 8th to the 16th centuries.d13C and d15N signatures for six possiblecatch regions were established using a larger sample of archaeological cod cranial bones (n=249). The data stronglysupport the second hypothesis, revealing widespread importation of cod during the 13th to 14th centuries, most of itprobably from Arctic Norway. By the 15th century, however, eastern Baltic cod dominate within our sample, indicating thedevelopment of a substantial late medieval fishery. Potential human impact on cod stocks in the eastern Baltic must thus betaken into account for at least the last 600 years

Article Reference Stable isotopes reveal patterns of diet and mobility in the last Neandertals and first modern humans in Europe
Correlating cultural, technological and ecological aspects of both Upper Pleistocene modern humans (UPMHs) and Neandertals provides a useful approach for achieving robust predictions about what makes us human. Here we present ecological information for a period of special relevance in human evolution, the time of replacement of Neandertals by modern humans during the Late Pleistocene in Europe. Using the stable isotopic approach, we shed light on aspects of diet and mobility of the late Neandertals and UPMHs from the cave sites of the Troisième caverne of Goyet and Spy in Belgium. We demonstrate that their diet was essentially similar, relying on the same terrestrial herbivores, whereas mobility strategies indicate considerable differences between Neandertal groups, as well as in comparison to UPMHs. Our results indicate that UPMHs exploited their environment to a greater extent than Neandertals and support the hypothesis that UPMHs had a substantial impact not only on the population dynamics of large mammals but also on the whole structure of the ecosystem since their initial arrival in Europe.

Article Reference Stable isotopes unveil one millennium of domestic cat paleoecology in Europe
The domestic cat is the world's most popular pet and one of the most detrimental predators in terrestrial ecosystems. Effective protection of wildlife biodiversity demands detailed tracking of cat trophic ecology, and stable isotopes serve as a powerful proxy in dietary studies. However, a variable diet can make an isotopic pattern unreadable in opportunistic predators. To evaluate the usefulness of the isotopic method in cat ecology, we measured C and N isotope ratios in hundreds of archaeological cat bones. We determined trends in cat trophic paleoecology in northern Europe by exploiting population-scale patterns in animals from diverse locations. Our dataset shows a high variability of isotopic signals related to the socio-economic and/or geomorphological context. This points toward regularities in isotopic patterns across past cat populations. We provide a generalized guide to interpret the isotopic ecology of cats, emphasizing that regional isotopic baselines have a major impact on the isotopic signal.
