摘要:

In skeletons excavated from Woodland sites, copper and barium levels are found to have been contaminated by influx from the soil environment. Electron microprobe scans for both elements show build‐up along the outer surface of femur cross sections. Elemental levels for Cu and Ba are lower in the femur or fibula than in the more porous rib. The distribution of Cu in the immediately surrounding soil is highly anisotropic. These observations indicate that Cu and Ba should not be used for dietary inferences about ancient populations without independent evidence that diagenesis is not importan

摘要:

Optical and scanning electron microscopy, electron microprobe analysis and X‐ray diffraction are used to determine the composition and microstructure of the bodies and glazes of Chinese porcelain of the Yuan dynasty from Jingdezhen, as well as samples of porcelain‐stone and glaze‐stone from the same region. The original mineralogical compositions of the porcelain bodies and glazes are estimated. The results indicate that the yingqing porcelain bodies were made using a kaolinised porcelain‐stone whereas the underglaze blue porcelain bodies were prepared by the addition of kaolin to a kaolinite‐free porcelain‐stone. In both cases, the glazes were made by mixing ‘glaze‐ash’ (i.e. lime) with the porcelain stone used t

摘要:

The thermoluminescence (TL) method of dating stalagmitic calcite has been applied to twenty‐seven samples from two paleolithic cave sites; Pontnewydd, Wales, and Caune de l'Arago, Tautavel, France. Environmental dose‐rates were evaluated mainly by means of CaF2capsule burials. The ages of the stalagmitic samples were independently determined by means of the uranium series disequilibrium method. In general, good agreement is found between the TL and uranium series dates, which cover a range from approximately 15 000 to 300 000 years B.P. It is estimated that the TL method should extend to the order of a million years in good circumstan

摘要:

A comparison is made using a 3D model between the response of the magnetic prospection (M.) response and the electromagnetic (E.M.) prospection one for the same feature. From this comparison the investigation depth of both methods is discussed. Three other main points are then studied: the influence of the shape of the feature and of the primary field, the significance of the measurements and the influence of parasites. Contrary to some preceding studies, the conclusion points out that the E.M. method is very valuable and more interesting to develop than the M. method.

摘要:

A system is described whereby readings from an earth resistance meter may be recorded automatically on a small portable computer. Field tests have demonstrated that the system is more reliable and more economical than manual recording, and that the results may be processed quickly and conveniently into their final form.

摘要:

Existing hypotheses concerning the speed and timing of the recolonisation of Britain by man after the last glaciation have largely been developed in the absence of securely‐dated Later Upper Palaeolithic (LUP) sites in the marginal areas of colonisation. In Kirkhead Cave, the most important LUP site in northern England, palynological, molluscan and palaeomagnetic evidence indicate that LUP occupation did not commence until mid‐pollen zone III of the Late‐glacial. This suggests later and slower colonisation of marginal areas than indicated by previous hypot

摘要:

Roman glass found at Jalame, in Western Galilee, and dating from the fourth century A.D., shows a variety of colors ranging from aqua blue to green to amber. It was found that the glasses are quite reduced and that the colors arise from absorptions by Fe2+and a ferri‐sulfide chromophore. Small amounts of colorless and purple glass, which had been oxidized by adding MnO2, were also foun

摘要:

Chemical analyses have been made of Roman wares found in Cologne and of bearded man jugs found both in Cologne and Frechen. The question of the influence of the approximately 1600 year difference in time between the manufacture of the two major groups of wares is addressed. It is concluded that the Roman wares were very probably made of Frechen clay.

摘要:

Chemical and petrographic studies of the two 720‐ton ‘Colossi of Memnon’ located near Luxor, and of Egyptian quartzite quarries indicate that the rear pedestal blocks of the northern statue were quarried at Aswan, while the other, main components of the monuments were quarried near Cairo. Our studies suggest that the rear pedestal blocks of the northern statue were part of the reconstruction project undertaken by Roman emperor Septimius Severus. Our studies of the tilting of the statues further suggest that the rear part of the lower torso of the northern statue was moved when the statue was reconstructed. Part of the present‐day tilting of the northern statue probably occurred prior to the reconst
