大约以公元前2200年为界, 老虎山文化可分为前、后两大期.前期稳定发展,对外影响有限;后期向南强烈扩张,其陶双鋬鬲、卜骨和细石器镞更流播至黄河中下游广大地区.老虎山文化后期对外扩张的加强和这一时期气候日渐干冷有关. 相似文献

In luminescence dating, the potassium concentration significantly contributes to the dose rate value in the age estimation. Within this study, fine-grain thermoluminescence dating has been applied on sherds of calcareous pottery of known age, excavated at a Roman site in Mallorca, Spain. For those of the samples that showed signs of severe potassium leaching, according to chemical and mineralogical examination, the thermoluminescence analysis provided overestimated dates. By using the known archaeological age of the samples, a corrected dose rate value can be estimated which provides the potassium concentration averaged for the burial period. Finally, a step-like model can then be used to estimate the fraction of the burial period after which most of the alteration effects took place. 相似文献

The lead isotope compositions of many different samples from lead ingots of Roman age from two relicts (from Cabrera, and from Saintes‐Maries‐de‐la‐Mer) of the Western Mediterranean have been measured. Other lead isotope analyses of ores, metals or lead ingots from mines of Sierra Morena and from Cartagena and Sardinia have been accomplished. All the lead isotope measurements have been performed at the Joint Research Centre of the European Union, Ispra (Va), Italy. The samples have been prepared in a class 100 clean room, using only ultrapure reagents and FEP materials. In view of the archaeological arguments, it was possible to believe that the Roman lead ingots of the Saintes‐Maries‐de‐la‐Mer 1 wreck came from Spanish lodes, as well as those of the Cabrera 5 wreck. In fact, while the comparison between the first group of ingots (Cabrera 5) and the lead from Sierra Morena is consistent, the correspondence between the second group of ingots (Saintes‐Maries‐de‐la‐Mer 1) and the Cevennes ores (southern France) gives rise to several problems concerning the archaeological and physical origins. These problems are discussed. 相似文献

“玉器时代”不是一个考古学的概念,90年代以来的反复讨论,使这个问题的缘起和内涵,也发生了变化。作者认为不应将《越绝书》所载的古代传说,与考古学分期的石器时代、青铜时代和铁器时代同等对待。 相似文献

The Bromme culture belongs to the Lateglacial, the period when people settled in the recently deglaciated Southern Scandinavia. Until now there have been only a few imprecise fix-points relating to the chronological position of this archaeological culture. This situation can now be improved with the aid of research results from a Bromme culture settlement at Trollesgave in SE Denmark. Using pollen and plant macrofossil data, Lateglacial lacustrine deposits containing waste material from the settlement can be assigned to the end of the climatically mild Allerød period. A series of 14C dates establishes the age of the settlement as c. 10 826 ± 49 14C years BP (12 871–12 590 cal yr BP). By correlation with climate data from the Greenland ice cores, the occupation can be assigned to the early part of the cold climatic zone GS-1, thus demonstrating that the global ice-core climate zones are not absolutely synchronous with the regional division into biozones. 相似文献

Considerable progress has been made in recent years in the study of the Lower and Middle Paleolithic of northern Asia. There is growing evidence for initial human occupation before 700,000 years ago—as early as elsewhere in Asia—and for a very early adaptation to the arctic desert environment. New models of Lower Paleolithic settlement involve expansion and reduction of occupation in response to climatic variation, rather than simple colonization followed by steady occupation. The Middle Paleolithic of northern Asia is better documented, including actual finds of archaicHomo sapiens. The transition to the Upper Paleolithic seems to involve the survival of earlier cultural traits, but the mechanisms and processes are not well understood. Further significant knowledge concerning these periods awaits the development of common methodologies for classification and analysis. 相似文献

清康熙年间,山东寿光县为缓解"大差"负担,将"大差"由轮当制改为下放给各社自理,但这进一步加重了民间劈社的窘境。乾隆年间知县王椿在缺少土地记录的情况下,采用"顺庄法"重整地方组织,缓解赋税征收的困境。以百姓实际居住的"庄",取代官方登记的里甲组织"社",作为税收登记与征收的基本单位。同时,这也形成了山东以"村庄"为基层组织的地方社会。因南北土地分布状况的差异,顺庄法在山东与江南显示出不同的形态与结果。 相似文献
