考古出土实物研究表明,商周青铜器铭文制作,通常是先雕刻正阴字铭文模,然后翻制反阳字铭文活块泥芯,镶嵌于主体泥芯合适位置组成复合泥芯,最后在浇铸青铜器时一并铸成于器物内壁上。复制具有151字铭文的西周晚期青铜颂鼎,整体采用失蜡铸造工艺,铭文制作借鉴商周青铜器陶范铸造的相关工艺,多次翻制制作一块铭文蜡片,嵌入模具型腔后翻制整体硅橡胶泥芯,获得了理想的效果。  相似文献

青铜箭镞是古代制造量最大、一次性使用的兵器,与要求甚高的青铜剑和青铜礼乐器等相比,在选材和表面处理等方面有很大的不同,其锈蚀过程最能反映材料在经过数千年后所产生变化。长江中下游地区环境潮湿,埋藏条件复杂,本研究利用扫描电子显微镜(SEM)、能谱仪(EDS)、X-射线衍射仪(XRD)、显微硬度等分析测试技术,从材料科学的角度对长江中游地区战国晚期古墓中出土的青铜箭镞的锈蚀现象和锈蚀机理进行了全面的研究和分析,以期为古代青铜器的保护提供更准确的信息和资料。结果表明,青铜箭镞的组织结构可分为完全矿化层、过渡层和心部原始材料等三个特征层,不同特征层具有不同的显微组织、化学成分、致密性,以及显微硬度等;并沿横截面观察和分析了锈蚀层中的微裂纹的性质和产生原因,即,平行于表面的裂纹是由矿化层氧化物膨胀引起的剥离开裂,其进一步发展将形成“粉状锈”,而垂直于表面呈放射状的裂纹是当圆柱形箭镞杆膨胀时,矿化层的塑性差,抗变形能力低而产生的开裂;锈蚀机理研究认为青铜器的锈蚀过程是环境中杂质元素通过过渡层沿界面能较高的α固溶体和(α+δ)共析体晶界或孔隙等缺陷逐步向内部扩散的结果。  相似文献

In its 1000-year history the port has been the source of triumph and tragedy for the city of Famagusta, being the conduit through which flowed both enormous wealth and destruction. Today the French medieval and Greek Orthodox churches, and the Venetian walls, though ruined, still carry physical traces of this turbulent society in the form of ship graffiti. Though such images are often classified as 'low-art', they are nevertheless imbued with a deep social significance, which the maritime historian can yet use to get a glimpse of an important, though virtually-forgotten, heritage in the Eastern Mediterranean.

This paper reports the earliest securely dated evidence for intentional dental modification in West Africa. Human remains representing 11 individuals were recovered from the sites of Karkarichikat Nord (KN05) and Karkarichinkat Sud (KS05) in the lower Tilemsi Valley of eastern Mali. The modified anterior maxillary dentitions of four individuals were recovered from KN05. The dental modification involved the removal of the mesial and distal angles of the incisor, as well as the mesial angles of the canines. The modifications did not result from task‐specific wear or trauma, but appear instead to have been produced for aesthetic purposes. All of the filed teeth belonged to probable females, suggesting the possibility of sex‐specific cultural modification. Radiocarbon dates from the site indicate that the remains pertain to the Late Stone Age (ca. 4500–4200 BP). Dental modification has not previously been reported from this region of West Africa and our findings indicate that the practice was more widespread during prehistory.

This study describes the archaeological investigations that have taken place at the wreck site of the English slave ship Henrietta Marie (1700) since its location in 1972. Information is provided on the methodology utilized during on-site archaeological data recovery, and the artifacts retrieved from the wreck site are described in detail. An account of complimentary documentary research on this wrecked slaver is also presented. Contemporary historical data gleaned from shipping lists, slaver’s logs, seamen’s wills and other sources are utilized to place Henrietta Marie within her proper context as a vehicle involved in the notorious transatlantic slave trade.  相似文献

The First Mallorcans: Prehistoric Colonization in the Western Mediterranean   总被引:1,自引:0,他引:1  
The paper aims to elucidate the first human colonization of the western Mediterranean island of Mallorca by answering such questions as: What was the cultural identity of the first archaeologically identifiable human settlers? What was the chronology of colonization? Where did the colonizers originate? And what were their contacts during the initial phase of settlement? It is based on recently acquired chronological data and on a review of the classical sources. A precise chronology for the first colonization event is proposed, supporting the idea that human settlement on Mallorca started within the period 2350–2150 cal BC. The coast of Languedoc, between the rivers Vidourle and Rhône, is the most probable source region. Whether the first settlers were derived from an Early Bronze Age or a Late Copper Age mainland culture remains unresolved. A rapid initial population growth following initial colonization is proposed. The available evidence points to the development of an essentially isolated population on Mallorca, developing an autochthonous culture with only limited contacts to mainland regions.  相似文献

We explore diet and mobility in Middle Archaic Florida using human burials and faunal remains from the Harris Creek archaeological site (8Vo24) on Tick Island. We conducted stable carbon and oxygen isotopic (δ13C, δ18O) analyses of 50 human enamel samples and strontium isotopic (87Sr/86Sr) analysis of a subset of 10. Most individuals (46/50) subsisted on local freshwater and terrestrial resources, with relatively depleted δ13C values (C3) and δ18O values matching those of central and north Florida water resources within the St. Johns River valley. Eight of 10 burials have local, within valley 87Sr/86Sr values. Two human burials yield marine δ13C and 87Sr/86Sr values, which we interpret as evidence for across valley movement from the coast. Another two individuals show depleted δ18O values, likely obtained from northern rivers. We also identified potential food resources and non-local foods from the Harris Creek faunal assemblage. We found six species with estuarine and marine habitat preferences; two of which, whelk and quahog, indicate that people of Harris Creek traveled to or traded with coastal areas.  相似文献

This article presents and discusses the chronological layout of the final Mousterian and Uluzzian levels of Fumane Cave in northern Italy using 14C, ESR and TL methods. Given its complex sedimentary and cultural succession, Fumane is a key site to assess the Middle–Upper Palaeolithic transition in Southern Europe and to explore Neanderthal behaviour and to compare it with the first Aurignacians. Large ranges defined by the ESR and TL dates cover the radiocarbon ages for units from A11 to A4, respectively, from 42.8 to 32.5 ka BP become progressively younger in agreement with the stratigraphy, despite high dispersions within the same unit. Our estimates using chronometric data seem to support the hypothesis that the sequence may cover almost 10,000 radiocarbon yr and that from comparison with the sedimentological and palaeoecological data, the late Middle Palaeolithic and the early Upper Palaeolithic at Fumane occur in sediments formed under moderately cool to mild climatic conditions correlated to the Hengelo-Interstadial, shifting towards cooler and drier conditions. Finally, comparisons between the Fumane data set and other sites in the North-Adriatic region are discussed.  相似文献

2005年,在湖北随州市黄土岗遗址发现一处新石器时代环壕,整体近似椭圆形,南北长约316、东西宽约235米。壕沟平均宽度15~20、平均深度2.5~3米,最深处超过3.8米。沟内的出土遗物均为陶器。壕沟的形成年代应不晚于屈家岭文化晚期,延用至石家河文化早期,可能具有防御功能。  相似文献
