Early Paleoindian Mobility and Watercraft: An Assessment from the Mississippi River Valley

Several researchers have suggested use of watercraft during the Early Paleoindian period 11,500 and 10,800 rcybp (13,400–12,700 cal B.P.), but none have brought empirical data to bear on this possibility. This paper addresses the potential for fluted point-making groups to have made and used boats circa 11,000 rcybp (13,000–12,800 cal B.P.). Fluted point data from a large region of the upper and central Mississippi River valley strongly suggest that the Mississippi River was a barrier to movement and that Early Paleoindians in the midcontinent did not routinely use watercraft.     

Continental Patterns in Stone Tools: A Technological and Biplot-Based Comparison of Early Late Pleistocene Assemblages from Northern and Southern Africa

The technology of the end products i.e. blades and points in Late Pleistocene stone artefact assemblages from Klasies River, South Africa, and the Nile Valley, Egypt, are compared. The comparison includes univariate and multivariate analysis of metrical attributes enhanced by graphical biplot displays. The end products in these assemblages are either dominantly points or blades and this is related to the core reduction strategy adopted. The MSA 11 from Klasies River and the Nubian Complex industry from the Nile Valley are point industries made in the Levallois tradition, while the MSA 1 from Klasies River and the Taramsan from the Nile Valley may be non-Levallois or adapted Levallois blade industries. Dating of the assemblages shows the changes between dominant core reduction strategies are sequential and time restricted in both South and North Africa. It is concluded that variability of the same kind occurs in Middle Stone Age and Middle Palaeolithic assemblages south and north of the Sahara in the early Late Pleistocene.Dans cet article, les technologies des produits recherchés, des lames et des pointes, pour certains ensembles lithiques de Klasies River, Afrique du Sud et la Vallée du Nil, Egypte, sont comparées. Cette comparaison implique des analyses univariées et multivariées de variables métriques biplot. Les produits recherchés sont bien des pointes que des lames, selon les stratégies dexploitation adoptées. Le MSA II de Klasies River et le Complexe nubien de la Vallée du Nil sont des industries à pointes issues de la tradition Levallois. Par contre, le MSA I de Klasies River et le Taramsien de la Vallée du Nil évoquent une technologie de production non-Levallois ou Levallois modifiée. Les éléments de datation disponibles indiquent que les changements dans la prépondérance des stratégies dexploitation senchaînent dans une séquence chronologique bien identifiable, aussibien dans lAfrique du Sud que lAfrique du Nord. On arrive à la conclusion quune variabilité du même caractère est attestée dans les ensembles du Middle Stone Age et du Paléolithique moyen au sud et au nord du Sahara, pendant le Pléistocène supérieur ancien.     

Precipitation of lead–zinc ores in the Mississippi Valley‐type deposit at Trèves,Cévennes region of southern France

The Trèves zinc–lead deposit is one of several Mississippi Valley‐type (MVT) deposits in the Cévennes region of southern France. Fluid inclusion studies show that the ore was deposited at temperatures between approximately 80 and 150°C from a brine that derived its salinity mainly from the evaporation of seawater past halite saturation. Lead isotope studies suggest that the metals were extracted from local basement rocks. Sulfur isotope data and studies of organic matter indicate that the reduced sulfur in the ores was derived from the reduction of Mesozoic marine sulfate by thermochemical sulfate reduction or bacterially mediated processes at a different time or place from ore deposition. The large range of δ³⁴S values determined for the minerals in the deposit (12.2–19.2‰ for barite, 3.8–13.8‰ for sphalerite and galena, and 8.7 to ?21.2‰ for pyrite), are best explained by the mixing of fluids containing different sources of sulfur. Geochemical reaction path calculations, based on quantitative fluid inclusion data and constrained by field observations, were used to evaluate possible precipitation mechanisms. The most important precipitation mechanism was probably the mixing of fluids containing different metal and reduced sulfur contents. Cooling, dilution, and changes in pH of the ore fluid probably played a minor role in the precipitation of ores. The optimum results that produced the most metal sulfide deposition with the least amount of fluid was the mixing of a fluid containing low amounts of reduced sulfur with a sulfur‐rich, metal poor fluid. In this scenario, large amounts of sphalerite and galena are precipitated, together with smaller quantities of pyrite precipitated and dolomite dissolved. The relative amounts of metal precipitated and dolomite dissolved in this scenario agree with field observations that show only minor dolomite dissolution during ore deposition. The modeling results demonstrate the important control of the reduced sulfur concentration on the Zn and Pb transport capacity of the ore fluid and the volumes of fluid required to form the deposit. The studies of the Trèves ores provide insights into the ore‐forming processes of a typical MVT deposit in the Cévennes region. However, the extent to which these processes can be extrapolated to other MVT deposits in the Cévennes region is problematic. Nevertheless, the evidence for the extensive migration of fluids in the basement and sedimentary cover rocks in the Cévennes region suggests that the ore forming processes for the Trèves deposit must be considered equally viable possibilities for the numerous fault‐controlled and mineralogically similar MVT deposits in the Cévennes region.     

Watercourses and Discourses: Coalmining in the Upper Hunter Valley,New South Wales

ABSTRACT Water is a resource that both unites and divides people in the Upper Hunter Valley of New South Wales, where many communities are facing the prospect of large‐scale open‐cut coalmining developments on productive mixed use land, or already live in proximity to mines and power stations. This article analyses conflicts over a proposed coal mine at Bickham in the Upper Hunter Valley, by contrasting the various protagonists' discourses of water scarcity, supply, and connectivity. It examines the ways in which the terms of opposition are narrowed to the arena of state and industry supported science and economic development, marginalising other cultural values and environmental ethics that are integral to opponents' discourses. Opponents have achieved some measure of success through contestation of the uncertain science of hydrological modelling, bolstered by the context of drought and increasing public acceptance of climate change science.     

Prehistoric dental modification in West Africa – early evidence from Karkarichinkat Nord,Mali

This paper reports the earliest securely dated evidence for intentional dental modification in West Africa. Human remains representing 11 individuals were recovered from the sites of Karkarichikat Nord (KN05) and Karkarichinkat Sud (KS05) in the lower Tilemsi Valley of eastern Mali. The modified anterior maxillary dentitions of four individuals were recovered from KN05. The dental modification involved the removal of the mesial and distal angles of the incisor, as well as the mesial angles of the canines. The modifications did not result from task‐specific wear or trauma, but appear instead to have been produced for aesthetic purposes. All of the filed teeth belonged to probable females, suggesting the possibility of sex‐specific cultural modification. Radiocarbon dates from the site indicate that the remains pertain to the Late Stone Age (ca. 4500–4200 BP). Dental modification has not previously been reported from this region of West Africa and our findings indicate that the practice was more widespread during prehistory.

Made in the Nene Valley? Identifying the origins of mortaria using ICP analysis

The Nene Valley, in eastern central England, was a major pottery production centre in the Roman period. Many kiln sites have been identified in the Lower Nene Valley region and, although comparatively less is known about production in the Upper Nene Valley, substantial amounts of mortaria and other coarse wares have been recovered during excavations at Roman sites in the area, and much of it is thought to be locally made. However mortaria made in the Upper and Lower Nene Valley can be difficult to tell apart, and many also have similar forms and fabrics to mortaria produced in Mancetter–Hartshill, Warwickshire. Therefore ICP analysis was used in an attempt to identify the products of different regions.     

Following the plot of Bengt Pohjanen's Meänmaa: narrativization as a process of creating regional identity

This paper discusses the artistic and cultural work of one minority author and regional activist, Bengt Pohjanen, and how it constitutes a means for mediating regional identity narratives, constructing Meänmaa, the region straddling the border between Sweden and Finland in the Tornio River Valley. We will approach narrativization as a creative social action, focusing on the performative, social and political aspects of regional stories, and by this means impugning the division between territorial, bounded, and networked, unbounded, conceptualizations of regions. We will follow the narrative plot of Bengt Pohjanen's Meänmaa, pointing out how an artistic and cultural region becomes part of our social reality and how regional consciousness and identity become established and constantly renegotiated within and across national borders.     

Mapping Sxwóxwiymelh: A Pre-contact Settlement in the Upper Fraser Valley,Southwestern British Columbia

Abstract

Maps and mapping are fundamental to archaeology. Archaeologists sometimes fail to recognize that the maps we use and create are fraught, like material culture, with interpretive complexities. These complexities arise from the fact that maps are created with social meaning dependent on the context in which the map was created and used. Here, we relate our experience with maps and mapmaking at the pithouse settlement of Sxwóxwiymelh, in southwestern British Columbia. We review the mapping history of the site, highlighting the contexts in which the maps were constructed and how they influenced subsequent interpretations of the site. We describe our deconstruction of these earlier maps and how we combined them to create a more accurate and detailed map that presented a rendition of the site as it was prior to significant modern development. This process of map deconstruction and construction allowed us to see several previously unknown details about the ancient settlement (e.g., house form, relative house size, and feature spacing) of Sxwóxwiymelh. In general, this process provides conceptual and practical lessons for incorporating previously collected map data into archaeological research.     

UNESCO World Heritage Site of Lenggong Valley,Malaysia: A Review of its Contemporary Heritage Management

This article reviews contemporary heritage management through a systematically coded content analysis at one of Malaysia’s UNESCO World Heritage Sites: the Archaeological Heritage of the Lenggong Valley (AHLV). It evaluates the competency of the preliminary Conservation Management Plan (CMP) of AHLV by looking at the accuracy of five distinctive dimensions of the CMP in conveying the information about the sites and management objectives: the legislation related to the heritage conservation and management; the action and implementation of the management strategies; the level of stakeholder’s participation; and, finally, how the CMP integrates local values and ideas into management planning. The results show that contemporary heritage management planning at Lenggong Valley tends to prioritize the conservation of the archaeological values of the sites over other values (i.e. social, historical, and aesthetic values), and that planning has largely been in the hands of governmental agencies with limited involvement from local communities in the decision-making process.
