Optically stimulated luminescence (OSL) is applied to quartz extracted from mud mortar collected from Chavín de Huántar, an early Andean monumental center. The samples appear to have been only partially exposed to sunlight during construction, so a minimum age model is applied to equivalent dose distributions. Complications, including complex radioactivity, low sensitivity of the quartz, and limited sample, prevent high precision, but the 14 dates obtained cluster around 1000 BC largely in agreement with radiocarbon assays on charcoal also collected from the mortar. Results suggest a relatively rapid construction for the monument. This work develops OSL as a method for directly dating architectural mortar.  相似文献

With the word «exchange», the confusion is often made between the savage of social contract and the savage of the market. This paper would a contrario set the one against the other, in showing how the two characters agree in fact to two absolutely different kinds of argumentation, which the Enlightenment led to coexist according to very distinct issues. Then the modern term of «civil society» has never solved this ambiguity and we find here the matter of several teachings, because it is possible to think at once about what is a «concept», a «historicity» and a «citizen». Methodology, anthropology and politics come therefore into sight as three horizons of an analysis which does not want to reduce the equivocation, but rather to measure its wealth.  相似文献

Acadian expulsion from Nova Scotia and subsequent settlement in south Louisiana during the late eighteenth century have inspired numerous studies since the 1970s concerning their history, cultural practices, and ethnic identity. The transformative landscape of south Louisiana is the milieu where actions, experiences, and perception interconnect with collective memory and historical consciousness in the production of Cajun identity. The resulting historical narratives and commemorations constitute a heritage landscape known as Acadiana, where monuments, memorials, historic sites, and parks reaffirm and reproduce this identity. An historical archaeology of Acadiana, including a recent investigation of the Amand Broussard homesite, offers a unique opportunity for cultural analysis and historical critique.  相似文献

This study asks the question, “What happens when the colonizers become the colonized?” It examines the social, cultural and political-economic transformations that took place as first the British and then the Americans wrested control of Great Lakes fur trade from the French and their Native American allies. One result was the ethnic segmentation of the fur trade labor market, which attempted to relegate Canadiens to the role of fur trade laborers. In response Canadien traders constructed homes and identities that were constitutive of both their fur trade society heritage and their political-economic position.  相似文献

In the Histoire des deux Indes, the concept of civilization applies initially to the making of modern Europe since the fall of the Roman Empire, in which the commerce does much to promote the civil and political «enfranchisement» of the third-estate in sovereign states. For Raynal, this historical experience of Europeans serves as paradigm, based upon which he depreciates the civilization of the ancient empires of the two Indies, and also elaborates various political proposals for transformation, or even for abolition, of the European colonial empires. Thus, universalizing the political structure of modern Europe, and pursuing the realization of civil and political liberty in diverse modes, he announces the advent of historical and political space of the modern world, composed of nation-states against the background of the global commercial networks.  相似文献

Well constrained numerical ages of alluvial fan sediments are key to understanding the chronology of alluvial episodes and tectonic activity at the front of the Andean Precordillera. We tested the application of radiocarbon and optically stimulated luminescence (OSL) dating in the distal part of an alluvial fan five kilometers north of Mendoza. For OSL dating a large number of aliquots (n > 70) — each composed of ∼50 quartz grains — were measured in order to obtain reliable burial ages despite scattered dose distributions. Owing to a feldspar contamination in all samples, an infrared stimulation was inserted before each OSL measurement, which reduced the feldspar OSL signal successfully. By using the minimum age model we obtained stratigraphically consistent burial ages of alluvial deposits in a depth profile. The uppermost ∼1 m of sediment is composed of debris flow deposits buried 770±76 years ago. Three plant remnants used for radiocarbon dating from the same layer, however, yielded ages younger than 350 years, which are interpreted to underestimate the depositional age. Underneath the debris flow, a major unconformity cuts a series of distal alluvial fan sediments with interstratified floodplain deposits, which are composed of sandy and calciterich silt layers, respectively. Three samples from this unit which were distributed over one meter of sediment thickness yielded statistically concordant OSL ages of 12.3±1.2 ka, 12.3±1.2 ka, and 11.7±1.1 ka. The deposition of these sediments during the latest Pleistocene coincides with a phase of cool and humid climate, which occurred before the alluvial fan propagated farther into the foreland. The overlying debris flow sediments are associated with alluvial fan incision during the arid Late Holocene.  相似文献

This article presents a multidisciplinary analysis of a human skull with preserved soft tissue curated by a small museum in Boscastle, Cornwall, UK. The skull lacks a mandible and is coated in a black tar-like substance. Records left by a previous museum curator (now deceased) claimed the skull to be the head of a medieval execution victim. The skull was purportedly recovered from a London church that was destroyed during the Second World War where it had been kept in a carved oak box. If these details are correct, the skull would appear to have been venerated as a relic. The skull and box have been analysed using a range of techniques including computerised tomography, laser scanning, microscopy, infrared spectroscopy and radiocarbon dating. These analyses demonstrated the skull in fact to be that of an Egyptian mummy dating from the Ptolemaic period. Other instances have been noted of parts of Egyptian mummies being presented as European saintly relics, and the ‘Boscastle skull’ would appear to be an example of such. A wider point illustrated by the work presented here is that sufficient application of modern analytical techniques may reveal considerable information regarding human remains which otherwise have little or no provenance. This point strengthens arguments for the retention of such remains by curating institutions.  相似文献

The application of luminescence dating to young volcanic sediments has been first investigated over three decades ago, but it was only with the technical innovations of the last decade that such analyses became viable. While current analytical procedures show promise for dating late Quaternary volcanic events, most efforts have been aimed at unconsolidated volcanic tephra. Investigations into direct dating of lava flows or of non-heated volcanoclastics like phreatic explosion layers, however, remain scarce. These volcanic deposits are of common occurrence and represent important chrono- and volcanostratigraphic markers. Their age determination is therefore of great importance in volcanologic, tectonic, geomorphological and climate studies. In this article, we propose the use of phreatic explosion deposits and xenolithic inclusions in lava flows as target materials for luminescence dating applications. The main focus is on the crucial criterion whether it is probable that such materials experience complete luminescence signal resetting during the volcanic event to be dated. This is argued based on the findings from existing literature, model calculations and laboratory tests.  相似文献

“Powered cultural landscapes” is my term for landscapes that express social power dynamics. Historical archaeologists have not adopted or developed adequate definitions or theorizations of the terms “power” or “landscape.” Since these terms are predominantly considered separately in the literature, this article first briefly defines power and develops a heterarchical theory of power. Then cultural landscapes are defined and categories of human-landscape interactions are constructed. The bulk of the article applies my heterarchical paradigm to analyze the social power dynamics in selected examples of historical archaeological research concerned with each category of human-landscape interaction.  相似文献
