The exploitation of silver deposits in early medieval Europe: some documentary, economic and social problems

Archaeometry, EarlyView.
Abstract Focusing on Southern Europe, this article sheds light on the mining landscape of the early Middle Ages. Based on the current state of historical and archaeological knowledge, the article raises a number of questions that can be extended to other European regions.

Paleotemperature models of the Phanerozoic foci of hydrocarbon generation for wells belonging to the Severo-Kalinov and Kalinov fields in Tomsk region [PDF]

Нефтегазовая геология: Теория и практика
This paper suggests a new method of coupled paleotemperature modelling of the Nyurol Paleozoic basin and the blanketing younger Mesozoic-Cenozoic basin. Modelling show that under the geological and geophysical circumstances of the Severo-Kalinov and the ...

Lithic analysis in African archaeology: Advances and key themes

Archaeometry, EarlyView.
Abstract Stone artifacts (lithics) preserve for extended periods; thus they are key evidence for probing the evolution of human technological behaviors. Africa boasts the oldest record of stone artifacts, spanning 3.3 Ma, rare instances of ethnographic stone tool‐making, and stone tool archives from diverse ecological settings, making it an anchor for ...

The Provenance of Silver in the Viking‐Age Hoard From Bedale, North Yorkshire

Archaeometry, EarlyView.
ABSTRACT The acquisition of silver was a key motive propelling the Viking expansion out of Scandinavia; identifying the sources of Viking silver during the early part of the Viking Age can provide critical insights into the relative significance of western European and eastern, Islamic wealth in the Viking expansion.

An Archaeometallurgical Investigation on Some Archaeological Metal Finds From the Sasanian Site of Jahāngir, Western Iran

Archaeometry, EarlyView.
ABSTRACT Twelve metal artifacts from recent excavations at the Sasanian archaeological site of Jahāngir in western Iran have been analyzed. These items include both decorative and utilitarian artifacts. The samples were examined using micro‐X‐ray fluorescence (μ‐XRF), scanning electron microscopy with energy‐dispersive X‐ray spectroscopy (SEM‐EDS), and

Fecal Steroids as Tracers of Human Population and Waste Management Practices at the Ancient Maya City of Ucanal, Guatemala

Archaeometry, EarlyView.
ABSTRACT Geochemical data compiled from dried sediments from three water reservoirs at the ancient Maya city of Ucanal, Petén, Guatemala, reveal low to undetectable fecal biomarker concentrations. These low concentrations may be the result of the aerobic decay of sterols combined with well‐managed waste disposal practices.

High-MgO lavas associated to CFB as indicators of plume-related thermochemical effects: the case of ultra-titaniferous picrite-basalt from the Northern Ethiopian-Yemeni plateau [PDF]

A comprehensive petrological and geochemical dataset is reported in order to define the thermo-compositional characteristics of Ti (Fe)-enriched picrite-basalt lavas (HT2, TiO2 3-7 wt%), erupted close to the axial zone of the inferred Afar mantle plume ...
