A review is undertaken of the nine species of Procytherura known to occur in Argentina and a new species, Procytherura serangodes sp. nov. is described. The global distribution of the genus indicates that it was more or less equally diverse and widely distributed in both hemispheres during most of the Lower and Middle Jurassic, but that in the Upper Jurassic and in the Lower Cretaceous, it became progressively restricted to the Southern Hemisphere. The widespread distribution of several Jurassic species of Procytherura, which occur in both Great Britain and Northwest Europe and in Argentina, is shown to be related to the availability of important migration routes, including the Tethys and the Hispanic Corridor. In the Lower Cretaceous, the very widespread distribution of Procytherura in the Southern Hemisphere, is used to support the existence of important routes along the eastern and western seaboards of Africa, the latter associated with the opening of the South Atlantic. 相似文献

Element ratios and water stable isotopes reveal the presence of only two independent deep brines in the Kinnarot Basin, Israel: the evaporite dissolution brine of Zemah‐1 and the inferred Ha’on mother brine (HMB) with low and high Br/Cl ratios, respectively. HMB is considered to be a representative of the Late Pliocene evaporated Sedom Sea. The freshwater‐diluted evaporation brine emerges as Ha’on brine on the eastern shore of Lake Tiberias and is also identified in the pore water of lake sediments. HMB is converted into Tiberias mother brine (TMB) by dolomitization of limestones and alteration of abundant volcanic rocks occurring along the western side of the lake. The Ha’on and Tiberias brines, both characterized by high δD and δ18O values, are similar in Na/Cl and Br/Cl ratios but are dissimilar in Br/K ratios because these brines were subjected to different degrees of interactions with rocks and sediments. Excepting the brine from KIN 8, all brines from the Tabigha area including the nearby off‐shore Barbutim brine are related to the TMB. The brine KIN 8 and all brines from the Fuliya and Hammat Gader areas are related to the HMB. The brine encountered in wildcat borehole Zemah‐1 is generated by halite‐anhydrite/gypsum dissolution and is independent from the HMB system. 相似文献

Flint was one of the most widely employed raw materials for artefact manufacture in Denmark and Sweden during the Stone Age, and it continued to be used during subsequent periods. Prehistoric flint mining and lithic manufacturing studies in these countries have attracted considerable attention, but there have been no recent attempts to chemically characterize the geological source materials. This paper builds on a pilot study ( Hughes et al. 2010 ) and uses energy‐dispersive X‐ray fluorescence (EDXRF) analysis to determine quantitative composition estimates for nine major, minor and certain trace elements in seven archaeologically significant flint sources in Denmark and Sweden, along with new data on a number of other sources of prehistoric significance. These data provide a geochemical foundation for ongoing research devoted to determining contrasts and continuities in the time and space utilization of flint sources in Scandinavian prehistory. 相似文献

There are various possibilities for the selection and scaling of ground motions for advanced seismic assessment of buildings using nonlinear response-history analyses. As part of an on-going project looking at building-specific loss assessment in Italy, this article highlights a number of challenges currently facing the use of conditional spectra for ground motion selection in practice, essentially related to the limited amount of seismic hazard information that is publicly available. To illustrate the points being made, the challenges faced when trying to develop conditional spectra and select spectrum-compatible accelerograms for a rock site in Napoli, Italy, are described and the seismic assessment results obtained for a number of reinforced concrete wall structures are presented. Aside from providing practitioners with an appreciation of the potential difficulty associated with using conditional spectra for record selection, this technical note should also motivate national authorities to provide more background information on national seismic hazard data and detailed guidance for record selection. 相似文献

This paper explores the relationship between rock music, collective memory and local identity, by focusing on events connected to Liverpool's status as European Capital of Culture 2008. The first part of the paper describes these events and how memories of local rock music were attached to heritage and local identity and mobilised to validate Liverpool as a capital of culture, whilst in turn the city's Capital of Culture status served to validate particular ways of remembering the local musical past. The second part of the paper considers the broader significance of these events by relating them to three pan-European trends in cultural policy: the development of the cultural and heritage industries; the protection and promotion of local culture and identity; and the fostering of cultural diversity and integration. It highlights the general significance of the popular music past for cultural policy in Europe, but also the politics of popular music memory and how it involves a complex and dynamic process of negotiation that relates to cultural policy in particular ways. The paper concludes by arguing that popular music offers a specific and productive focus for research on cultural policy, heritage and local identity in Europe. 相似文献

This article explores the reactions of civil authorities and Lutheran clergy to Mormon activity in Finland between the years 1875 and 1889. At this time, Mormonism was introduced to the country by missionaries who were mainly Swedish natives and who proselytized in the Swedish-speaking coastal areas. Although the impact was numerically small in terms of conversions, the Mormon presence was regarded by the civil authorities and the Lutheran clergy as sufficiently serious to warrant action. Civil authorities responded for example by confiscating Mormon literature and issuing warnings and threats of arrest to missionaries. Clergy, acting from a religious perspective and seeking to impede the spread of new religious movements that they regarded as spiritually harmful, interrupted preaching meetings and warned their parishioners against the perceived heresy. Enforced legislation and strong societal opposition was an important reason for the meagre harvest of Mormon converts in 19th-century Finland as opposed to the other Nordic countries. 相似文献

The paramilitary ceasefires in 1994 and the ensuing peace negotiations brought to a close some three decades of ethno‐nationalist violence in Northern Ireland. The conflict, colloquially termed the Troubles, cost almost 3,700 lives, and bequeathed both a tangible and intangible heritage of division and hurt. This paper considers the commodification of physical conflict ‘heritage’ such as military installations, memorials and street murals through an examination of various tourism initiatives. Such initiatives have been employed by a number of agents ranging from local councils and tourist boards to small community groups and ex‐prisoner organisations. While ‘official’ agencies recognise the economic potential of this form of heritage, community‐based groups often view the sites and symbols of the conflict as vehicles through which to propagate political perspectives. Those sold by the latter, in particular, are often supported by government bodies that fund such forms of tourism under the auspices of ‘conflict transformation’, a strategy that is aimed at transforming the nature of the conflict through fostering self‐understanding within disputant communities. I participated in a number of these tours over the course of six months in 2005/2006. 相似文献

As new media technologies increasingly populate our toolkits, questions arise about whether archaeologists are yet even competent
users of orthodox media. Prior to engaging with emerging tools, this paper takes one step back to probe the subtexts of traditional two-dimensional
archaeological images. Of interest is whether the many implications of these images can be made poignant via personally manipulating
and imposing upon their form and function. Influenced by the work of various playwrights, artists, anthropologists, cultural
theorists, and archaeologists, this paper examines what is legitimate in our practices of picturing the past, and what it
means to explicitly—perhaps illicitly—interfere with typical archaeological visuals. Via tentative experiments with assorted
maps, photos and illustrations, I endeavour to turn these orthodox modes of engagement into more defiant tools of discovery
and critique. Ultimately, my objective is to disrupt convention and prompt archaeologists to confront and respond to themselves
(and their responsibilities to others) in their everyday interactions with media. 相似文献
