THERMOLUMINESCENCE DATING OF BURNT FLINT AND QUARTZ: COMPARATIVE RESULTS

Thermoluminescence dates obtained from burnt flints and quartz recovered from the same sites are compared. For the Upper Perigordian level at la Vigne Brun (Loire, France), four quartz specimens and three flints yielded average ages of 27 400 ± 2300 and 26 900 ± 2200 years respectively, which are 15% greater than the radiocarbon age obtained for the same site (Evin 1982). For the neolithic site of la Vallée aux Fleurs (Loir et Cher, France), the respective averages of three flints and three ceramic sherds were 6830 ± 560 and 6570 ± 520 years.     

CHARACTERIZATION AND THERMOLUMINESCENCE DATING OF PREHISTORIC POTTERY SHERDS FROM MILENA

This paper reports the results obtained applying absolute dating methodologies and mineralogical, petrographical and micropalaeontological characterization techniques to prehistoric pottery sherds varying in age from the Sicilian Middle Neolithic to Bronze Age. All samples came from the archaeological area of Milena (Caltanissetta, Sicily); those of the Bronze Age were found on a site with a precise stratigraphic succession. The investigation has contributed to the determination of an absolute chronology for the Milena prehistoric period. The data provide, for the first time in Sicily, absolute dates covering a wide spectrum of cultures following one another in the same area and, for the Bronze Age site, correlated to the precise stratigraphic succession. The petrographical and mineralogical analyses allowed not only the identification of the principal constituents of the pottery, but also the formulation of some hypotheses regarding the specific manufacturing techniques of different epochs. The microfacies, obtained from the presence of fossils in the groundmass of the pottery, were also analysed and compared with the microfauna present in the Miocene clays outcropping in the area. The data identified local Messinian clay as the raw material probably used in the manufacture of the pottery and also support the presence, already assumed by archaeologists, of imported Mycenaean pottery, thus supporting the dates obtained on pottery taken from the same stratum.     

THERMOLUMINESCENCE DATING OF STALAGMITIC CALCITE

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 CaF₂ capsule 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 circumstances.     

萧梁钱范原料的矿物组成及其处理技术初探

一、引言通过大量的实物观摩和资料调研 ,我们发现萧梁铸钱工艺思想之先进 ,钱范的设计、布局之合理 ,钱范的制作水平之高 ,体现了高超的工艺水平和丰富的科学内涵。萧梁钱币叠铸工艺思想先进且技术上也存在相当大的难度 ,这就说明 ,萧梁钱范如果不具备一定的优良性能 ,是不可能满足萧梁钱币叠铸的复杂工艺的。按照现代铸造学和造型材料的理论 ,并且参考有关学者对古代陶范研究的成果①②③ ,可知萧梁钱范应具有下列基本性能 :1 可塑性、复印性、脱模性良好 ;2 足够高的干湿强度和干硬度 ;3 足够高的耐火度和化学稳定性 ;4 收缩 -膨胀率…     

THERMOLUMINESCENT AUTHENTICITY STUDIES OF UNGLAZED T‘ANG DYNASTY CERAMIC TOMB GOODS

Imitations of T‘ang Dynasty (a.d. 618–906) ceramics were produced at the beginning of this century casting them from original piece-moulds. The impeccable style of these wares means they are indistinguishable from their ancient prototypes by visual inspection. Examples of such imitative material are revealed by thermoluminescent dating analysis. A brief discussion of the need for and methods of the piece-moulding technique in its use by the T‘ang artisan is also given.     

商代亲称区别字若干问题研究

目次一商代亲称前的数字问题二商代亲称前的大、中、小问题三商代亲称中的"高"与"毓"四结语简单而言,亲属称谓是指那些反映人们亲属关系的称谓,如祖、妣、父、母、兄、弟等一系列基本称谓。商代亲属称谓前的区别字意义重大,它和亲称共同规定了成员的家族乃至社会角色。然而,对于区别字问题,此前学者虽已有很好的讨论,但仍存留诸多问题有待进一步研究。     

THERMOLUMINESCENCE AND STYLE IN THE AUTHENTICATION OF CERAMIC SCULPTURE FROM OAXACA,MEXICO

Oaxacan urns, the most characteristic esthetic expression of Zapotec culture in ancient Mesoamerica, are an important potential source of information for archaeologists and art historians, but relatively few exist with specific archaeological context and many are suspect as forgeries. This paper reports the thermoluminescent authenticity determinations of over one hundred Oaxacan urns as a first step toward confirmining a sequence previously determined by stylistic analysis. We tested a collection of 117 urns on loan to the St Louis Art Museum, mostly acquired after 1960, and another group of 6 from the Peabody Museum, Harvard, acquired before 1930. Our hypothesis that more recent collections would contain fewer forgeries was confirmed and a number of stylistic criteria for determining authenticity are critically examined in the light of the results.

边境旅游研究综述及展望

作者总结了国内外关于边境旅游的研究进展。指出国外研究的成果主要集中在目的地合作和冲突管理、边界效应与旅游影响等方面;国内研究侧重于旅游产品规划与开发,旅游目的地空间结构和管理等方面,国内整体研究水平不高。分析认为,在全球化和区域经济一体化背景下,加强边境旅游的区域性综合研究,重视旅游边界效应的测度,进而揭示跨境合作的内在机理,是中国边境旅游研究的重要方向。     

A COMPARATIVE ELECTRON MICROPROBE STUDY OF LERNA III AND IV CERAMICS AND LOCAL CLAY-RICH SEDIMENTS*

This study uses electron microprobe analysis of ceramic artefacts and local day-rich sediments and lithics to help address questions concerning the nature of the cultural change implied by ceramics from Lerna III and IV. It redresses the previous lack of a comparative collection of clay-rich sediments that adequately represents the local variation in clay and temper for the area surrounding Lerna. The resulting comparisons indicate that although they produced stylistically different ceramics, potters from both Lenta phases acquired their clays from the local Lerna area.
