Coarse wares from western Cyrenaica and southern Crete are similar in shape and workmanship and are not distinguished petrologically. It has been possible to identify three distinct groups by neutron activation analysis: (1) Keratokambos (Crete); (ii) Benghazi lime-rich ware; (iii) Benghazi shell-rich ware. The element ratios for (ii) and (iii) are 1·52 ± 0·16 (excluding Na) which suggests a dilution of clay from the same source by shell for example in the shell-rich ware.The element ratio for Na is only 1·01 and the Na concentration increases linearly with time. This could be Na absorption with time from the brackish water for which the region is renowned.  相似文献

The Longmen Grottoes, also known as the Longmen Caves or Dragon's Gate Grottoes, are located near the city of Luoyang, Henan province, China. The grottoes were carved into the limestone cliffs during the period from 493 AD to 1130 AD. Limestone samples from different areas within the grottoes were analyzed by neutron activation analysis (NAA) to determine the concentrations of major, trace and rare-earth elements (REEs). Three compositional groups were identified corresponding to different areas within Longmen Grottoes. X-ray diffraction (XRD) was performed on a few samples to obtain information about the mineral structure. The results indicate that rocks in the northern area are comprised of dolomite, while rocks in the middle and southern areas are comprised of limestone. The NAA results provide information useful for identifying and relocating fragments from the grottoes that may have lost their identity. The compositional data also provides important clues regarding the geologic history of the limestone formation at Longmen.  相似文献

Using instrumental neutron activation analysis (INAA) of prehistoric pottery, daub, and modern clay samples from Valencia, Spain, we tested expectations on changes in raw material use with socio-economic shifts during the Neolithic (ca. 5600–2800 BC). Elemental analysis identified three distinctive clay source groups used by Neolithic potters. Contrary to expectations, a shift in raw material use was identified between the Early and Middle Neolithic despite general similarities in technological practices. In the Late Neolithic, pottery production became more specialized, but potters used the same range of clay sources documented earlier. This study illustrates the utility of INAA for testing hypotheses of prehistoric craft production.  相似文献

The emergence of archaeological interest in native copper in the mid-1800s developed in concert with explanations that privileged the Lake Superior area over other potential sources of copper. Most scholars have thus assumed that when copper artifacts first appeared in Northeastern North America, they arrived as finished implements or were locally made from Lake Superior raw materials. Procurement models that point to Lake Superior as the sole source of native copper have been widely accepted in the absence of systematic large-scale testing. This article evaluates the dominant model for native copper procurement and presents trace element data derived from instrumental neutron activation analysis (INAA) to determine whether hunter-gatherers in the Northeast utilized one dominant source of copper or in fact exploited a number of geological deposits. I specifically report on the chemical characterization of copper from 13 discrete geological deposits and 18 archaeological sites dating to the Late Archaic (ca. 5000–3000 B.P.) and Early Woodland (ca. 3000–2000 B.P.) periods to suggest that the dominant model for native copper procurement is oversimplified.  相似文献

To examine regional patterns of ceramic production and distribution during the era of Inka domination in northern Chile, we determined the elemental compositions of 157 samples of archaeological ceramics and geological clays from the sites of Catarpe and Turi using instrumental neutron activation analysis. We identified two major and three minor composition groups in the ceramics. The major groups, High Cr and Low Cr, are linked to clays from two broad geological contexts within the region, while the minor Low Na group is made up of ceramics imported from northwestern Argentina. The distribution of the composition groups indicates that, in the Catarpe–Turi region, patterns of ceramic production differed for different vessel types: jars were made from clay and temper acquired near the sites where the jars were used, while bowls were made of material coming from more distant sources. The geographical distribution of the analyzed ceramics indicates that bowls were exchanged between Catarpe and Turi in a pattern more similar to tribute/extraction than to market exchange, with Catarpe being the dominant site. The compositional analysis also demonstrates that Inka-style ceramics were being locally produced at sites in this region during the era of Inka domination.  相似文献

Metallography and neutron activation analysis have been used to investigate copper artifacts from 19th century archaeological sites associated with the “Copper Inuit” of the west-central Canadian Arctic. A knowledge of the source of the copper from which the artifacts were manufactured - native (local) copper or European (exotic) copper - is important, for example, to studies of the effects of European contact on utilization of native copper and on the general lifestyle of the Copper Inuit. Trace element analysis by neutron activation using the SLOWPOKE reactor has allowed local native copper, from the Coppermine River and Victoria Island, NW Territories, to be clearly distinguished from 19th century European smelted copper, which was found to contain higher concentrations of arsenic, antimony, nickel and selenium. Moreover, optical and scanning electron metallography revealed significant microstructural differences between native copper and the 19th century smelted copper. As a consequence it was possible to differentiate between native copper archaeological artifacts and those produced from smelted copper.  相似文献

In 2006, as part of the Flinders University Maritime Archaeology Field School, Department of Archaeology staff and students excavated and recorded the remains of the Australian-built ketch Mary Ellis . Colonial-period Australian shipbuilding has, for the past 20 years, been considered one of the most important themes in Australian maritime archaeology. This paper presents a summary of field investigations and a preliminary interpretation of the shipwreck, which adds to the slowly-building dataset on this theme of Australian maritime archaeology.

19世纪收继问题研究——以安徽为中心   总被引:1,自引:0,他引:1  
19世纪安徽社会中收继现象较为普遍,平均14%的家庭发生收继或出继行为,来解决一些家庭的"无后"的问题.从宗族角度讲,收继可以分为族内收继和族外收继两种情形,各需履行不同的收继程序,中上层家庭以族内收继为主,下层家庭则族外收继多于族内收继.国家和宗族对收继的前提、原则和被收继人在新旧家庭中的地位做出种种规定,但制度规范与人们的实际行为间存在着相当的差异.  相似文献

Abstract

Rene Descartes presented a number of reasons for his choice of the pineal gland as a logical place for the soul to interact with the physical machinery of the body. It is often stated that one of his reasons was that be believed animals do not have pineal glands, whereas humans alone possess a soul and this small structure. This is a misinterpretation of Descartes. The philosopher knew that barnyard and other animals possess pineal glands, having seen this with his own eyes. His point was that the pineal is unique in humans only because of a special function — acting as the seat for the rational soul.  相似文献

Cultural landscapes were prominent during the Early Roman period when agronomic knowledge allowed the spread of intensive land exploitation in most of the available land. The aim of this contribution is to explore whether for the Campania region (Southern Italy) archaeoenvironmental data would support continuity or change in the cultural landscape of Roman tradition in the 4th and 5th centuries. To do so, new data from two sites located on the northern slopes of the Vesuvius, both buried by the AD 472 eruption have been investigated. Charcoal analysis, 14C dating, and chemical analysis of organic residues were carried out in order to study the landscape and the food production at these sites. The results suggest the persistence of the Roman cultural landscape until the 4th and 5th centuries in this area. The landscape is in fact strongly marked both in agriculture and woodland exploitation and management, being characterized by managed chestnut forests as well as valuable cultivations of walnut, large vineyards, olive groves, and probably orchards and crops. The integrated approach with archaeobotanical and archaeometric analyses proves to be a powerful method for the study of the past landscapes, providing a good insight into the environment. Furthermore, this study provided the most ancient evidence of chestnut silviculture for wood.  相似文献

A portable XRD/XRF system and complementary laboratory techniques were employed to improve the knowledge of the procedures used to create Roman and Arabic wall paintings. Integrated physico-chemical investigations were conducted on fragments of artworks collected from the archaeological excavation of the Patio de Banderas in the Reales Alcazares’ Palace of Seville (Spain), and a comparative study on the pigments from both historical periods was performed. As a result, pigments such as vermilion, red ochre, yellow ochre, green earth, Egyptian blue, carbon and phosphor-based black pigments were detected in Roman samples; however, in the Arabic fragments, only haematite was observed. In addition, the size and shape of the particles of the wall paintings were studied with an XRD 2-dimensional detector and SEM-EDX.  相似文献

19世纪初期“tourism”见诸英语,后又取代“travel”的主流地位,标志着英国古典旅行观向现代旅游观的转变。“tourism”概念由于适应了工业文明时代旅游大众化、市场化、产业化的需要,因而从市井俚语上升为20世纪西方旅游理论的主流概念。厘清它与汉语中“旅游”概念之间深刻的文化差异,是中国旅游学界应对西方旅游理论的一大关键。  相似文献

On 3 March 1677, French Vice‐Admiral Jean d'Estrées launched an assault on an inferior Dutch squadron, commanded by Jacob Binckes, anchored in Rockley Bay, Tobago. The French attack was defeated, but a total of 12 warships on both sides were sunk. The Rockley Bay Research Project, supported by the Institute of Nautical Archaeology and the University of Connecticut began an archaeological investigation of the battle in 2012. At least one of the Dutch men‐of‐war lost in the battle has been found, TRB‐5. The article is a preliminary report on the work that has been carried out so far.  相似文献

Late Bronze Age Handmade Burnished Ware (HMBW) from Tell Kazel was studied by thin-section petrography and neutron activation analysis in order to investigate its manufacturing technology and origin of production. Results show that the majority of the HMBW fabric groups point to a local area of production while a few petrographic loners might have been produced elsewhere in the Akkar Plain or imported. The manufacturing technique, in terms of clay paste recipe, forming and finishing techniques, is however new in the Tell Kazel pottery assemblage, hinting at the work of foreigners present at the site. The historical and archaeological contexts further suggest that these foreigners were some of the Sea Peoples and the stylistic and analytical data further reinforce the link between the northern Levant and the western Mediterranean.  相似文献

Elemental analysis of pottery is a valuable scientific approach to investigation of its provenance. Increasing use is being made of the approach, and this paper presents a critical review of the basic methodology and experimental procedures. Genenal problems and limitations of the technique are discussed, and the procedures involved in each of the four main stages of such studies are described. These stages are: (1) selecting specimens of pottery for analysis, (2) obtaining samples from the specimens, (3) analysing the samples, and (4) interpreting the results. For each stage, suggestions are made for generally useful procedures and experimental precautions, and for aspects on which further study seems desirable. Much of the discussion is also relevant to the analysis and typing of artifacts of other materials, e.g., metal and stone objects.  相似文献

The survival of late medieval Mediterranean techniques to conceive and build ships and boats in Brazil was noted by John Patrick Sarsfield in the 1980s, but his study of the Valença shipwrights was interrupted by his untimely death in 1990. This paper summarizes Sarsfield's account of these shipbuilding techniques, examines that published by Lev Smarcevski (1996), and provides some preliminary results of the pilot stage of a project to further research traditional shipbuilding in Valença and the Baía de Todos os Santos region.  相似文献

Instrumental neutron activation analysis (INAA) of the bones of a 6th century case (AD ) of hypertrophic osteoarthropathy (HOA) showed high levels of Zn, Mn and K in the periosteal new bone. The concentration of Zn in the periosteal new bone appeared to be biogenetic in origin and connected with active mineralization processes in the abnormal bone tissue. Manganese and potassium concentrations were, at least partly, related to diagenetic processes.  相似文献
