Yeha, in Tigray, is the most impressive site with evidence for South Arabian influence dating to the first millennium BC in
the northern Horn of Africa (Eritrea and northern Ethiopia). The evidence from this site was used to identify a ‘Pre-Aksumite’
or ‘Ethiopian-Sabean’ Period (mid-first millennium BC) when an early Afro-Arabian state apparently arose in the region. A
‘Pre-Aksumite Culture’, characterised by South Arabian elements, was also suggested as a distinctive archaeological culture
in northern Ethiopia and Eritrea. However, recent fieldwork in these countries suggests that a Pre-Aksumite culture actually
did not exist and South Arabian features were restricted to a few sites, which were scattered in a mosaic of different archaeological
cultures in the first millennium BC. This hypothesis is tested through a comparison between the ceramics from Yeha and those
from Matara and other sites of the first millennium BC in Tigray and Eritrea. 相似文献

Several decades after the discovery of the spectacular Nahal Mishmar Hoard (a collection of cast metal goods, some quite ornate, found in a cave high in the cliffs of the Judean Desert) many important questions about Chalcolithic metallurgy in the southern Levant remain unanswered. What is the origin of the materials used? Where were the final goods produced and what were the dynamics of production? In fact, new questions have also arisen as recent discoveries force us to reconsider previous interpretations of Chalcolithic metallurgy and the societies within which it evolved. Such will be the focus of this paper. 相似文献

The loess site at Boynychi (the Volyn Upland) is of essential importance for the stratigraphy of Middle and Upper Pleistocene
in Central Europe. The profile was recently dated by Fedorowicz and Prylypko in 2007 (parallel dating), and by Kusiak in 2009.
The Upper Vistulian loesses are much thicker in the exposure from 2009 than in the earlier examined one (2007). The list of
results obtained in the Gdańsk, Kiev and Lublin laboratories, respectively, can be divided in two. The first group contains
the results obtained for the Horohiv and Korshiv pedocomplexes and for the loess from the penultimate glacial, which separates
these pedocomplexes. The results from all laboratories are very similar and rather well describe the real age of dated deposits.
The second group contains the widely differing results of dating of the Vistulian loesses. The TL ages obtained by Fedorowicz
and Prylypko are considerably older than those obtained by Kusiak in the new exposure. The latter ones excellently correspond
to the geologic-stratigraphic interpretation of the profile. Two incompatible series of TL dating results indicate that local
variability of loess accumulation conditions in different stages of their formation may have resulted in incomplete luminescence
zeroing of mineral material before deposition. 相似文献

Mumba rockshelter is a key archaeological site for the Middle and Later Stone Age occupation of East Africa, but its chronology
has remained unresolved. We report the results of a dating study, focussing on the characterisation of the optically stimulated
luminescence (OSL) and infrared stimulated luminescence (IRSL) properties of quartz- and potassium-rich feldspar grains. Quartz
has previously proven troublesome for dating in East Africa. We identified five general types of quartz grain behaviour, based
on the shapes of their OSL decay and dose–response curves. Dose recovery experiments and measurement of the natural samples
revealed particular problems with quartz grains that had hyperbolic dose–response curves, low characteristic saturation doses
and anomalously large changes in sensitivity between regenerative-dose cycles. The use of pulsed irradiation during measurement
and standard and additional quality-assurance criteria during data analysis reduced the number of grains that suffered from
these problems. We applied these procedures to individual grains of quartz from eight samples and, using appropriate statistical
models, identified post-depositional mixing in three samples. The remaining samples had scattered equivalent-dose distributions
typical of quartz grains that had received variable beta dose rates during burial. Stratigraphically consistent OSL ages were
obtained for all but the deepest sample. Feldspar ages were estimated for the latter sample and three other samples, using
the elevated temperature IRSL signal that exhibited low rates of anomalous fading. Fading-corrected feldspar ages for the
latter three samples are consistent with their single-grain quartz ages, but single-grain dating is needed to address problems
of post-depositional mixing. 相似文献

This study uses stable isotope analyses (δ13C and δ15N) of human bone collagen to reconstruct the diet of three Romano-British (first to early fifth century AD) populations from
Gloucestershire in South West England. Gloucestershire was an important part of Roman Britain with two major administrative
centres at Gloucester (Glevum) and Cirencester (Corinium) and numerous smaller settlements and farmsteads. To investigate
potential dietary differences between the rural and urban populations of Roman Gloucestershire, we compared human bone collagen
stable isotope values from 32 individuals from urban Gloucester with those of 46 individuals from two rural cemeteries at
Horcott Quarry and Cotswold Community, respectively. Seven individuals from urban Gloucester were buried in a mass grave;
all others were buried in single inhumations. Results show small but significant differences in stable isotope ratios between
the urban and rural populations which indicate that the urban population might have consumed slightly more marine and/or freshwater
resources than the people living in the rural communities. We interpret this difference as a direct reflection of Rome’s influence
on Gloucester’s population and the town’s economic status. Subtle differences in stable isotope ratios were also observed
at the site level, as burial practice does correlate with diet in some cases. Overall, the results from this study demonstrate
that diet, as reconstructed through stable isotope analysis, is a very sensitive, if settlement-specific, indicator of social
differentiation and culture change. 相似文献
