摘要:

New absolute dates have been obtained for the Bilzingsleben (D.D.R.) archaeological site, using uranium‐series analyses of travertine, and electron spin resonance (ESR) analyses of travertine and tooth enamel of rhinoceros. The results indicate that the site was apparently occupied during interglacial isotope stages 9 or 11. The surrounding terrain has been subsequently dissected by at least three discrete stages of fluvial erosion during succeeding glacial stages. Bilzingsleben is thus shown to be significantly older than the Lower Travertine at the nearby site of Ehringsdorf, assigned to isotope stage 7 by uranium‐series dating. The latter assignment is confirmed by new ESR data presented h

摘要:

This article reports a generalised and systematic approach to the thermoluminescence (TL) dating of samples which suffer from anomalous fading. We hypothesise that the TL signal from each mineral phase is composed of a stable and an unstable portion. The decay of the unstable TL is accelerated thermally, until only stable TL remains. The dating is then carried out on this stable signal. The results, on four known‐age, coeval samples, exhibiting gross anomalous fading (25‐50% loss over a few days), indicate that many, if not all, samples may successfully be dated with this appro

摘要:

The effect of purifying, mixing and firing of clays on trace element concentration was systematically investigated using instrumental neutron activation analysis. Eight different clays from two sites in Crete were used together with sherds found around several kilns near the sites. Trace element analysis showed that the extent to which the concentration changes after purification and firing depends on the initial particle size and chemistry of the clay. The calcite concentration plays an essential role in this. An application is made using roof tiles found at the excavation of the ancient city of Pella in Macedonia.

摘要:

A new similarity measure is proposed, the ‘dilution factor spread’ or, derived from it, a ‘goodness of fit’ parameter. This has the advantage that raw data without any transformation can be used, diluted samples are recognized and errors of individual concentration values can easily be included. The use of this similarity coefficient in multivariate cluster analyses to construct dendrograms is shown and compared with the use of the well‐known similarity measure of Euclidian distance in attribute space and of the co

摘要:

The reliability of uranium‐series dating of fossil bones and teeth is studied. On this basis the first absolute chronology for about 20 important Chinese palaeolithic sites is proposed. A two‐stage model for open‐system samples is disc

摘要:

European mixed‐alkali glasses are compared with Sayre and Smith's categorisation for ancient glass and with the chemical compositions of other prehistoric and later European glasses. The new categories reported here indicate that a wide range of alkali raw materials was used in the production of glasses found in prehistoric European contexts. At least five major chemical categories of glass are now known to have been used in prehistoric and early Roman Europe. A plant species of the genus Sulicorniu is suggested as a possible alkali source in ancient European glasse

摘要:

A description is provided of the analytical and statistical methods used in a study of the later prehistoric pottery of the Western Isles of Scotland. The accuracy and precision of the methods used are discussed and results are presented for the analysis of a set of clay samples from known locations. The study indicates that the methods employed provide an adequate means of characterizing clays from the various sources used. In addition the use of ratios of element concentrations to the scandium concentration for individual samples provides a better classification than does the use of concentrations rather than ratios.

摘要:

A computer‐based pattern recognition procedure has been applied to trace element data obtained from marble samples of different Mediterranean quarries. Nineteen elements, mostly hydromagmatic and rare earth elements were first determined by neutron activation analysis. These elemental concentrations are then used as the data for further multivariate analysis. The results indicate significant differences in chemical patterns of the marble source

摘要:

This article reports the results of analysis of samples collected from some Egyptian quartzite artifacts. such as statuary, dating from the New Kingdom. Most of the artifacts are located in Upper Egypt, but the results of analysis suggest that, until the middle of the fourteenth century B.C., the quartzite came from a more distant quarry near Cairo rather than from the quartzite quarries located near Aswan in Upper Egypt.
