Particle induced X‐ray emission (PIXE) has been used in analysis of ink and paper of the 42‐line Bible and other early printed works. Results are reported and their significance discus

摘要:

Dates from the first runs of the Oxford Radiocarbon Accelerator Unit span the range from present toc.17,000 bp, with errors (1 s.d.) from ± 100 to ± 300 years. Material dated comprises bone, wood, charcoal, seeds, organic residues in pottery, and charcoal inclusions in sla

摘要:

Field tests were conducted to determine if an object buried near the surface could be detected by monitoring the surface temperature of the soil. A series of tests using various object depths and thermal diffusivities were made with a portable infrared thermometer. In addition, a three‐dimensional, implicit computer simulation was used to model and normalize the data. The method of underground detection investigated appears to be effective not only in locating a buried object but also in estimating its thermal diffusivity. Furthermore, some idea of object shape and depth can be obtaine

摘要:

The lead, cadmium and zinc content of deciduous and permanent teeth extracted from Romano‐British skulls was measured using atomic absorption spectrometry. Mineral content is reported in μg/g of samples obtained by pulverising whole teeth prior to chemical preparation and analysis. The overall levels of lead and zinc were higher in deciduous than permanent teeth.Lead levels in conservatively cleaned teeth were twice as high in deciduous compared to permanent teeth but were reduced following abrasive removal of surface enamel especially in deciduous teeth. It was concluded that the higher lead content in deciduous teeth is mainly in the outer layer of enam

摘要:

Fatty material from a Thule Eskimo site on Herschel Island, Yukon Territory, Canada was analysed by gas chromatography and thin layer chromatography. The fatty acid composition of the samples was then compared with published data for a number of marine species which could have been food sources for the Thule peoples. The samples appear to be derived from seal or whale, or a mixture of these, but what is more surprising is that the fats have changed so little over the 1000 year period of their burial.

摘要:

A technique for making acetate peels of tools using Triafol is outlined. A series of ‘blind tests’ is described where the suitability of this replica material for reproducing the details of usewear was tested. The advantages and disadvantages of the use of acetate peels are discussed with reference to examination of usewear tra

摘要:

In the past, studies on the average chemical composition of a sherd vs its origin have successfully been carried out, but attempts failed to reach the same goal with spot analysis (electron microprobe) on the high gloss surface of terra sigillata. When chemical data on the average composition of the surface is used for provenance determinations, significant results are obtainable on the basis of non‐destructive energy dispersive X‐ray fluorescence analysis (EDS‐XFA). Terra sigillata from Arezzo, Lezoux, La Graufesenque and Lyon (± 20 B.C. to ± 150 A.D.) were analysed in order to determine the statistically distinctive chemical elements. It is clearly possible under favourable conditions to allocate archaeologically unknown sherds to specific pottery

摘要:

Sherds from the Chalcolithic levels at Teleilat Ghassul show evidence of a considerable degree of sophistication in pottery technology and design. The bodies are almost certainly made from a siliceous illitic clay which contained some calcium carbonate, and was obtained locally. Some unusual, yet common, sherds are composed of highly vitrified black bodies with a surface wash of a refractory white clay. These sherds indicate the production of one of the earliest known totally vitrified ceramic fabrics. The latter sherds have been examined in some detail by chemical, thermal and X‐ray analysis, and optical and scanning electron microscop
