Before the main burst of agricultural improvements, taking place in Scotland in the latter part of the eighteenth century, farming was carried out from fermtouns; these were groupings of farmsteadings and their fields. This paper seeks to determine the factors underlying the decisions that were taken in the location of the farmsteads and the different elements into which the agricultural land was divided. Isolated for examination are the distance-decay function and natural environmental factors, basically those of soil conditions. The importance of natural soil drainage conditions appears to decide the location of both intensively and extensively cultivated land while in many cases the farmsteadings also lie closest to the permanent arable land. Definite statements about the decision-making process cannot, however, be made due to our present rudimentary understanding of the stability of settlement sites and the true origins of the infield-outfield system. 相似文献

New Insights into the Provenance of the Obsidian Fragments of the Island of Ustica (Palermo,Sicily) 下载免费PDF全文
F. Foresta Martin A. Di Piazza C. D'Oriano M. L. Carapezza A. Paonita S. G. Rotolo L. Sagnotti 《Archaeometry》2017,59(3):435-454
In this study we applied a multidisciplinary approach, coupling geophysical and geochemical measurements, to unveil the provenance of 170 obsidian flakes, collected on the volcanic island of Ustica (Sicily). On this island there are some prehistoric settlements dated from the Neolithic to the Middle Bronze Age. Despite not having geological outcrops of obsidian rocks, the countryside of Ustica is rich in fragments of this volcanic glass, imported from other source areas. The study of obsidian findings was carried out first through visual observations and density measurements. At least two different obsidian families have been distinguished, probably imported from Lipari and Pantelleria islands. Analysing the magnetic properties of the samples, these two main sources were confirmed, but the possibility of other provenances was inferred. Finally, we characterized the geochemical signature of the Ustica obsidians by performing microchemical analyses through electron microprobe (EMPA) and laser ablation (LA–ICP–MS). The results were compared with literature data, confirming the presence of the Lipari and Pantelleria sources (Sicily) and indicating for the first time in this part of Italy a third provenance from Palmarola island (Latium). Our results shed new light on the commercial exchanges in the peri‐Tyrrhenian area during the prehistoric age. 相似文献

Microstructural and Componential Characterization of the Plating Technology on Chinese Han Dynasty Bronze Fragments 下载免费PDF全文
The bronze wares of the Han Dynasty excavated in Chongqing are decorated with plating patterns, maintaining an exquisite lustre right up to modern times after the covering patina is cleared away. In this paper, a plated fragment of the Han Dynasty from the Wushan County Museum was characterized by combining optical microscopy (OM), scanning electron microscopy with X‐ray energy‐dispersive spectrometry (SEM–EDS), X‐ray fluorescence analysis (XRF), X‐ray diffraction (XRD) and X‐ray photoelectron spectroscopy (XPS). The results showed that the bronze fragment was gilded with a ~ 3 μm thick gilded layer and a ~ 20 μm thick silvered layer. The high concentration of Hg and Hg‐rich intermetallic compounds confirmed the existence of mercury gilding/silvering technology, for example, Au9Hg in the gilded layer and Ag13Hg7 in the silvered layer. An ordered stripe structure was observed in the gilded surface, corresponding to the formation of rod‐like, intermetallic Au–Hg compounds. Specifically, a high concentration of Au was detected in the silvered layer. The exploration of gilded/silvered bronze casts light on this ancient technology and the benefit of identifying, protecting and reproducing it. 相似文献

A Multidisciplinary Approach for the Archaeometric Study of Pozzolanic Aggregate in Roman Mortars: The Case of Villa dei Quintili (Rome,Italy) 下载免费PDF全文
C. M. Belfiore G. V. Fichera M. F. La Russa A. Pezzino S. A. Ruffolo G. Galli D. Barca 《Archaeometry》2015,57(2):269-296
This contribution focuses on the study of historical mortars from a Roman archaeological site known as Villa dei Quintili, a monumental villa located in the south‐eastern part of Rome (Italy). The study was carried out on 38 mortar samples, collected from several edifices within the complex. A multi‐analytical approach, including polarized optical microscopy, scanning electron microscopy coupled with energy‐dispersive system and laser ablation inductively coupled plasma mass spectrometry, was used to analyse the pozzolanic material used for the preparation of mortars. Data obtained on both major and trace elements were compared with the compositions of Pozzolana Rossa, Pozzolana Nera and Pozzolanella samples from the Alban Hills volcanic district, collected from a historic quarry nearby, as well as with literature data. The results of such a multidisciplinary approach allowed us to recognize the use of all three pozzolan types for the aggregate fraction of examined mortars from the Villa dei Quintili. 相似文献
