An archaeological GIS is used to examine the late eighteenth-century cultural landscape of St. John, US Virgin Islands. Land
use patterns are reconstructed using a combination of historic maps, tax records, and survey reconnaissance. The study demonstrates
significant, heretofore undocumented, transitions taking place that reflect dynamic cultural and economic change within Danish
West Indian plantation society that includes a significant trend towards land ownership by free-colored St. Johnians more
than a half a century before emancipation. These venues of freedom are discussed in relation to broader patterns of estate
consolidation and economic shifts. 相似文献

Archaeologists generally agree that Paleoindian residential groups moved regularly over extremely large ranges. However, on the Great Plains, this argument depends substantially on datasets derived largely or entirely from projectile points rather than from systematic analysis of a wide range of artifacts. This paper argues that projectile points differ from most Paleoindian tools in ways that make such datasets unlikely to be reliable sources of information on range sizes. Furthermore, evidence from Paleoindian tool caches and the condition of discarded points suggest strongly that the raw material used to produce projectile points at least sometimes moved across the Plains independently of material used to make most other kinds of flaked stone tools. This, in turn, implies that not all stone used during Paleoindian times was procured by visits of whole residential groups to raw material sources, raising serious questions about the validity of widespread views of Paleoindian mobility. 相似文献

Seasonality determination using stable oxygen isotope (δ18O) analyses in archaeological mollusk shell has been largely limited to aquatic settings where one of the two factors that control shell δ18O – water δ18O (or salinity) and temperature – is assumed to be constant. Open coastal marine environments reflect the former situation, and tropical estuaries constitute the latter. In an effort to expand stable isotope seasonality to an ecological setting where neither variable remains constant, we present a model of annual shell δ18O cycle of aragonite deposition derived from instrumental data on salinity and temperature from San Francisco Bay, California. The predicted range of modeled shell δ18O is consistent with observed δ18O values in prehistoric and modern shells when local conditions are considered. Measurements of δ18O taken at 0 mm and 2 mm from the terminal growth margin were made on 36 archaeological specimens of Macoma nasuta from a late Holocene hunter-gatherer site CA-ALA-17, and season of collection was inferred using the shell δ18O model. We conclude that shellfish exploitation occurred through the year with the exception of fall, which may indicate scheduling conflicts with acorn harvesting or other seasonally abundant resources elsewhere. The model supports the feasibility of stable isotope seasonality studies in temperate estuaries, provided that instrumental records are available to quantify the relevant water conditions at appropriate spatial and temporal scales. 相似文献

Slag inclusions are found within most archaeological bloomery iron artefacts and are remainders of slag created during the smelting and smithing processes. Although they are widely believed to provide data with the potential for provenancing iron artefacts, previous slag inclusion studies have mostly proven inconclusive. The main aim of the work reported here is to analyse experimental smelting and smithing assemblages (including ore, furnace lining, fuel and slag), to compare these to slag inclusions in the resulting bloom and worked objects, and then explore the relationships between ore, slag and slag inclusions. This study has revealed that the composition of slag inclusions most closely relates to the smelting slag produced, whereas provenance to a specific ore would be difficult due to the chemical variability derived from furnace lining, fuel and any fluxes used. Some compounds in the slag inclusions are particularly affected during smithing of the artefact, i.e. those present in the sand flux and fuel used. However, trends are observed in the K2O/MgO, MnO/SiO2, Al2O3/SiO2, Al2O3/MgO, Al2O3/K2O and Al2O3/CaO ratios that allow comparison between slag inclusions and smelting slag in these experiments, and may therefore be used during other provenancing attempts. The knowledge gained from the experimental assemblages was subsequently applied to an archaeological case study, examining objects from the 900 Cal BC smithing site of Tel Beth-Shemesh, Israel and the 930 Cal BC smelting site of Tell Hammeh, Jordan. The analyses suggest that none of the artefacts examined derived from the Hammeh smelting system. 相似文献

Islam came to China via the Silk Road, the great trading route beginning in the ancient Chinese capital of Xian. Islam flourished during the brutal but religiously tolerant Mongol Yuan dynasty. Harsh repressive measures were employed against the rebellious Muslims of the Qing dynasty. Islam has survived the tumultuous 20th century and has experienced a revival in the new millennium. Following a brief historical overview, including some of China's relevant history of insurrection, rebellion and reforms, the nature of the Muslim community in China, along with pressing contemporary issues, will be outlined and discussed. 相似文献

Stable carbon (δ13C) and nitrogen (δ15N) isotope analyses of dog (Canis familiaris), island fox (Urocyon littoralis), and human bone collagen from CA-SRI-2 (AD 130–1830) on Santa Rosa Island, California provide a proxy of diet and the relationships between humans and these animals. Carbon isotopic signatures indicate that Native Americans and their dogs at CA-SRI-2 subsisted almost exclusively on marine resources, while the island fox ate primarily terrestrial foods. Nitrogen isotopes and archaeofaunal remains indicate that humans and dogs also ate higher trophic level foods, including finfishes, marine mammals, and seabirds with smaller amounts of shellfish. The CA-SRI-2 island foxes appear to have eaten higher amounts of terrestrial foods, similar to the diets observed in modern fox populations. These data generally confirm the commensal relationship assumed to exist between domesticated dogs and people, but the carbon isotopic composition of dogs is enriched ∼2‰ compared to humans. We hypothesize that the difference in carbon isotopes between dogs and humans may have resulted from a higher consumption of C3 plants with lower δ13C values by humans, or less likely from the ingestion by dogs of significant amounts of bone collagen, which is enriched by ∼4‰ over associated muscle. 相似文献
