Tracking Bronze Age ‘itinerant smiths’ in western Poland: insights from Nd and Sr isotope data
Abstract The neodymium (Nd) isotope composition of stone casting moulds found in graves of Bronze Age ‘itinerant smiths’ in western Poland was analysed to determine the provenance of their raw materials. For the first time in archaeological research, the Nd model age (TDM)—a highly useful parameter in studying the provenance of geological materials—has

De Geer moraines may act as valuable ice‐marginal indicators; however, to date, their variable mode of formation has presented challenges for this utility. Here, we present sedimentological and ground penetrating radar data of DGMs located in southwest Finland.

This study contains a comprehensive regional analysis of the orientations of tunnel valleys, faults and salt structures in the North German Basin, aiming to identify correlations that might indicate a structural control on tunnel‐valley formation. A structural control on tunnel‐valley formation has been repeatedly postulated and correlations have been ...

Basal conditions that facilitate fast ice flow are still poorly understood and their parameterization in ice‐flow models results in high uncertainties in ice‐flow and consequent sea‐level rise projections. Direct observations of basal conditions beneath modern ice streams are limited due to the inaccessibility of the bed.
