方墩东周制盐遗址位于浙江省宁波市大榭开发区的大榭岛,出土了较多制盐陶器和少量日用陶器。制盐陶器均为放置在盐灶中以支撑煮盐器具的支臂和支脚,它们的制作可能已经有标准化倾向。结合遗址年代、位置、自然环境和文献记载来看,这是一处春秋晚期至战国早期由越国管辖的盐业生产聚落。 相似文献

喇家遗址四座齐家文化的房址分别于2000年和2001年发掘完成,在此后的数年当中,由于受到多方面因素的影响,房址及房内人类骨骸等都遭到了不同程度的损坏,改变了发掘清理后的原始状态.为了保护房址和人骨遗骸,对房址进行了物理复原加固和化学保护.采用金属锚杆牵入嵌入方式、沟槽内嵌入固定体方式、利用孔洞嵌放固定体进行土体夯筑方式等加固方法,并使用非水分散体丙烯酸树脂溶液进行喷洒或滴渗保护.结果显示,该方法的实施,可以使这一举世闻名的齐家文化之灾难遗迹重新展示于公众面前. 相似文献

The present paper is a review of the functional analysis of prehistoric flint tool edges by means of high-power microscopy. The article, which focuses exclusively on West European research, discusses a series of methodological issues and problems related to the development and distinctiveness of the so-called wear polishes, produced by the various materials with which prehistoric stone tools came in contact. A selection of functional observations on tool use from the Upper Paleolithic, the Mesolithic, and the Neolithic periods is presented. The archaeological part of the review is concerned with two trends in functional analysis, namely, (1) controlled site-specific studies with different levels of foci and (2) thematic studies of particular tool types, e.g., endscrapers, burins, and unmodified débitage. Finally, problems concerning the interpretation of hafting and of multiple tool use are discussed. 相似文献

The Yarabuoki underwater site contains seven iron grapnel anchors and Early Modern Okinawan ceramic jars and is dated to the 16th–19th centuries. The site lies at a depth of 12–32 m off the western coast of Ishigaki Island in Okinawa, Japan. Based on underwater archaeological and broadband multibeam surveys, as well as historical research of the artefacts and Early Modern Ryukyuan shipping, we discuss the possible anchor and vessel types in Ryukyu and Eastern Asia in Early Modern times. We also discuss the efficacy of low‐cost ROV for assisting surveys in shallow‐water environments and the value of educational programmes for promoting the management and conservation of underwater cultural heritage. 相似文献

This study deals with the mineralogical and chemical characterization of archaeometallurgical material from the Roman archaeological site of Castra (Ajdov??ina, western Slovenia). Samples were initially analysed via optical microscopy and X‐ray powder diffraction, with the composition of individual phases then determined using scanning electron microscopy coupled with electron‐dispersive spectroscopy, and Raman microspectroscopy. Chemical investigation was carried out by using inductively coupled plasma atomic emission spectroscopy to measure the major element content. The results showed that the slag originated from iron smithing operations, with calcium‐rich olivines, as well as wuestite and leucite, the most abundant phases. The investigated slags were also found to be characterized by significantly high lime levels, which probably promoted the formation of the calcium‐rich olivines. 相似文献

On October 31 and November 1, 2002, two earthquakes of magnitude 5.4 and 5.3 hit the area at the border between the Molise and Puglia regions in Southern Italy. The damage pattern in the epicentral area qualified the quake as an intensity VII MCS event, although providing a notable exception relevant to the small village of San Giuliano di Puglia. Since the first macroseismic survey, it appeared clear that in S. Giuliano the intensity was two degrees higher with respect to three neighbouring villages located within a radius of 3 km. Soon after the quake, our team started a campaign of microtremor HVSR measurements (Horizontal to Vertical Spectral Ratio), then we installed accelerometers and carried out damage and geological surveys. Finally, we performed a geoelectrical tomography and two profiles of Vs velocity with depth using the NASW technique (Noise Analysis of Surface Waves). The preliminary observations indicate that ground motion amplification is present in S. Giuliano within the frequency band that may affect building. A strong velocity contrast 20 m deep causes the predominant peak. More amplification could be due to more complicated, 2D effects. As regards the damage pattern, it divides S. Giuliano in three zones showing different characteristics and seismic behaviour. A building-by-building survey is still under way to better evaluate vulnerability variations in different zones of the village. However, the acquired data so far is sufficient to propose site amplification as a possible cause of the damage enhancement observed in S. Giuliano. 相似文献

We approach from a new standpoint the problem of estimating seismic hazard for some towns and villages located in Val d'Agri area (Southern Italy) that in the past have been affected by several seismic events. The estimates are carried out using a method that is based on the analysis of site seismic history extracted from macroseismic catalogues. To study the influence of site effects two different procedures have been performed: in the first, seismic hazard estimates have been deduced from epicentral data only, in the second, intensity data actually observed at the site are also considered. The difference between the two estimates can be correlated with local variations of seismic response due to local geological features which are responsible for possible cases of amplification. In order to validate the presence of such correlation, seismic hazard estimates have been compared to site amplification measurements obtained by using the HVSR (Horizontal to Vertical Spectral Ratio) technique. Our findings reveal a good correlation between seismic hazard enhancements and the presence of site amplification effects. The application of this kind of analysis to the Val d'Agri area has pointed out that the joint estimates of site seismic hazard enhancement and HVSR measurements could be a helpful tool to identify problems related to seismic microzonation. 相似文献
