Assessment of radionuclide distribution in silex by autoradiography in the context of dose rate determination for thermoluminescence dating doi

A combination of two autoradiography methods was applied to investigate the radionuclide distribution patterns in a range of different silices. We obtained greyscale images (β-radiation) and α-track patterns for qualitative assessment, and used a statistical approach to quantify the degree of uniformity of the radiation fields. It was found that almost all samples are poor in potassium, thorium and uranium, and that locally high concentrations are present only in dark-coloured veins and inclusions....

First chronometric dates (TL and OSL) for the Aurignacian open-air site of Româneşti-Dumbrăviţa I, Romania doi Spatial

Currently, absolute dates for the emergence of the Early Upper Paleolithic and the timing of the earliest dispersal of anatomically modern humans (AMH) into Europe are sparse. This is especially true for regions adjoining the Eastern Mediterranean and Central Europe with its dense clusters of sites along the Austrian and German Danube Valley. This article makes a first step toward filling this gap and, for the first time, presents absolute ages for the open-air site of Româneşti-Dumbrăviţa I (Banat, SW...

Towards reconstruction of past fire regimes from geochemical analysis of charcoal doi

Production of charcoal has accompanied human life from the beginning. We aimed at evaluating the degree to which the chemical signatures of charcoal may serve as a fingerprint for burning conditions. After a compilation of fire literature we differentiated three typical fire regimes [grass and forest ground (285 ± 143 °C), shrub (503 ± 211 °C) and domestic fires (797 ± 165 °C)] and three main factors impacting on charcoal formation: charring duration, temperature and fuel. For fingerprint calibration and...
