Late Holocene environmental history of Dojran, Macedonia: Investigating the interplay of imperial dynamics and climatic change

Journal of Quaternary Science, EarlyView.
ABSTRACT This study presents a high‐resolution, multi‐proxy reconstruction of environmental and land‐use change from Lake Dojran over historical times (last 2500 years), combining pollen, biomarkers, radiocarbon dating, Ottoman taxation records and other historical data.

A Clockwise P-T Path from the Variscan Basement of the Tisza Unit, Pannonian Basin, Hungary

Geologia Croatica, 2010
The polymetamorphic basement of the Tisza Unit forms a detachedfragment of the Variscan European foreland of the Neotethyanrealm. A clockwise evolution path of a gneiss-amphibolite complexof the Tisza Unit was reconstructed, investigating the ...

Ostracod faunal and geochemical evidence for the impact of Hoxnian (MIS 11c) sea levels in eastern England

Journal of Quaternary Science, EarlyView.
ABSTRACT Marine isotope substage 11c (~426–366 ka) is widely regarded as the most recent Pleistocene interglacial that is broadly analogous to the Holocene. The timing and magnitude of sea‐level changes during MIS 11 have been much debated, particularly concerning whether sea levels were significantly higher than during the Holocene. Empirical evidence

Geochemical Analysis of the 1-Alpine Federal Well, by Humble Geochemical Services, Humble, Texas

, 1995
Samples were analyzed to determine their organic richness, petroleum content, kerogen type, and maturity by TOC and Rock-Eval analysis. Confirmation of maturity on selected samples was completed using vitrinite reflectance and thermal alteration index ...

Using regional geochemical survey data to trace anomalous samples through geochemical genes: The Tieshanlong tungsten deposit area (Southeastern China) case study

, 2020
In order to determine and trace geochemical anomalies in soils, a tungsten (W) metallogene was constructed according to the idea of the gold (Au) metallogene previously developed.

New geochronological constraints on Late Pleistocene glaciation in the southern Cadí Massif, SE Pyrenees

Journal of Quaternary Science, EarlyView.
ABSTRACT The Cadí Massif (42°17′09″ N, 1°38′11″ E; 2649 m a.s.l.) in the southeastern Pyrenees preserves clear evidence of Late Pleistocene glaciation, although previous research has focused almost exclusively on its northern slope. By contrast, the southern slope has remained largely unexplored.

Managing and visualising geochemical data for tephra correlation with the IntChron Integration Tool

Journal of Quaternary Science, EarlyView.
ABSTRACT There is now a wealth of glass‐shard geochemical data for volcanic ash (tephra) layers from a wide range of volcanoes and eruptions, providing invaluable datasets for tephrochronology. However, compilation of published data to assess tephra correlations leads to large files and requires careful management.

Stable isotope analysis of freshwater gastropod carbonates from Swanscombe: Insights into climate stability and seasonality during MIS 11c

Journal of Quaternary Science, EarlyView.
ABSTRACT Stable isotope analyses of freshwater mollusc carbonate can record environmental conditions at the time of mineralisation, yet this technique remains underused in British Middle Pleistocene fluvial sequences, despite the abundance of fossil shell material in these deposits.
