Since the introduction of portable X‐ray fluorescence (pXRF) technology to obsidian provenance research, the volume of published studies has increased exponentially. This proliferation of data creates unprecedented analytic opportunities for the development of higher level archaeological theory but, at the same time, presents methodological challenges. Here, it is argued that rigorous analytic procedures are required to keep pXRF‐based provenance studies in line with the best scientific practice; specifically, the generation of accurate compositional data, the compilation of comprehensive reference databases for robust source characterisation and the development of appropriate methods for artefact assignment are essential components of a reliable protocol. To these ends, a reference dataset for New Zealand obsidians containing over 1500 samples is reported in this paper, previous source assignment methods are reviewed and a selection of multivariate approaches are evaluated. 相似文献

Primary questions regarding the foraging behaviour of the first hunter–gatherers who colonized the New World are how they found, procured and utilized high‐quality raw materials for manufacturing stone tools. In this paper, we present evidence from the late Pleistocene site of Cueva Bautista in the highlands of south‐western Bolivia, which demonstrates that a substantial portion of the recovered stone tool assemblage originated in Cerro Kaskio, a recently discovered obsidian source located 15 km south‐west of the site. In addition to describing the geological and geochronological setting, we provide the first geochemical characterization of the Cerro Kaskio source by means of instrumental neutron activation analysis and energy‐dispersive X‐ray fluorescence. Supported on the technological analysis and archaeometric sourcing of the obsidian lithics found in Cueva Bautista, we discuss the nature of the procurement strategies practised by the earliest mobile hunter–gatherers who explored and colonized the Andean highlands. We conclude that opportunistic lithic resource procurement was probably an important component of the first foraging societies that explored the highland Andes. 相似文献

Sources of lithic raw material discovered by the authors are described with special regard to methods of transporting stone to Upper Paleolithic sites in the northwestern Caucasus. The analysis of obsidian artifacts suggests that materials were imported from remote regions such as the central and South Caucasus, evidencing mobility patterns in the Upper Paleolithic. 相似文献

The Red Sea and surrounding area formed through dynamic uplift and rifting of Afro-Arabia, and associated volcanism (both oceanic and continental in character). As a result, volcanic landforms and products are widespread and play a vital role in the natural and cultural landscapes of humans occupying the highlands and lowlands on both sides of the Red Sea. Archaeologists have suggested for some time that Afro-Arabian trade in obsidian had its roots in the prehistoric period and that the region was very likely the source of an abundance of obsidian artefacts found as far afield as Egypt, the Persian Gulf and Mesopotamia, and which do not match the well-known Anatolian, Transcaucasian or Mediterranean sources. Nonetheless, the southern Red Sea is one of the few obsidian-rich regions exploited in antiquity that has been barely investigated. In this paper, we highlight new geochemical analyses (carried out by LA-ICP-MS) of obsidian sources in Southern Arabia and beyond, that enhance our knowledge of obsidian exploitation from as early as the Neolithic period, and which enable us to evaluate the role that highland Yemen obsidian sources played in prehistoric long-distance trade. In addition, we present new evidence for explosive volcanic eruptions that likely affected the highland populations of Yemen in the 4th millennium BC. 相似文献

The Teouma site on Efate Island in Vanuatu is unique in the Pacific, as it enables us to analyse an archaeological assemblage in relation to discrete activity areas of burial and settlement at the time of initial settlement of the archipelago. Geochemical sourcing of obsidian in combination with a basic technological analysis help us to understand whether differences exist between burial zones and settlement middens. The results show that the distribution of obsidian was not directly associated with individual burials and does not unambiguously correlate with specific activity areas, thus questioning the hypothesis that obsidian transportation was linked to the increase in individual status. It is argued that the evidence adds further weight to those models that interpret the function of obsidian as being associated with past social transactions or relationships, rather than having any enduring or intrinsic value as a wealth‐enhancing commodity. 相似文献

A geochemical study using pXRF and LA–ICP–MS to characterise artefacts from sites dating to the initial phase of colonisation on Aore and Malo islands, Vanuatu, has confirmed the dominance of obsidian from the distant Kutau/Bao source in West New Britain, with a smaller group from local outcrops in the Banks Islands, Vanuatu. Three flakes from the Umleang/Umrei source in the Admiralty Islands have also been identified in later levels. Distance fall‐off analysis of metric and technological attributes suggests that during the early phase of human colonisation of Remote Oceania, obsidian circulated within a series of separate, loosely connected social spheres. 相似文献

Sites which have been occupied semi-continuously in the past present some inherent difficulties for archaeology. Here we present new research from a coastal site on the North Island of New Zealand at Cooks Beach where anthropogenic vegetation changes are seen using microfossil analysis of obsidian tools, sediments and pit fill. The results indicate the initial presence of people in AD 1300–1400 followed by subsequent periods of disuse or abandonment and sweet potato (Ipomoea batatas) cultivation. Around the time of initial settlement, obsidian from this location is found at sites across the country. After AD 1400 the area appears to be deserted for a century or more, after which we see evidence for the cultivation of sweet potato in AD 1500 as evidenced by extensive soil modification and numerous storage pits. There is no evidence of a permanent settlement at the site. The geographic distribution of Cooks Beach obsidian was constricted while the site was used for sweet potato cultivation, a pattern often attributed to increased warfare. It appears cultivation was abandoned after AD 1650 marking a second secession of use, a fact confirmed in AD 1769 when Captain Cook visited the area. We consider the possible drivers for the late abandonment of cultivation at Cooks Beach. 相似文献

The occupation of small islands presents particular challenges for people largely related to limited terrestrial resources and susceptibility to natural disasters. Nevertheless, the challenges and risks inherent in maintaining stable populations on small islands can be offset or overcome through the use of maritime technologies and exchange networks. The archaeology of Here Sorot Entapa rockshelter (HSE) on Kisar Island in the Wallacean Archipelago provides an unparalleled record for examining these issues in Southeast Asia. Kisar is the smallest of the Wallacean islands known to have a Pleistocene occupation record, and one of the smallest permanently inhabited today. Our results indicate that Here Sorot Entapa was first occupied in the terminal Pleistocene by people with advanced maritime technology who made extensive use of local marine resources and engaged in social connections with other islands through an obsidian exchange network. As a result, populations appear to have been maintained on the island for approximately 6,000 years. In the early Holocene occupation at HSE ceased for unknown reasons, and the site was not reoccupied until the mid-Holocene, during which time a major change in the lithic resources can be observed and the exchange network appears to have ceased. 相似文献

One of the more visible tools in the Rapa Nui archaeological record is a large flake modified to form a broad blade and tang. Referred to as mata'a, these implements have conventionally been interpreted as “spear points”, or weapons of war, which are proposed to have been made in large numbers during a period of internal conflict in the late seventeenth century. Obsidian hydration dating of 63 mata'a fragments from the southern coast of Rapa Nui indicates that their usage peaked in the sixteenth century, declined in frequency afterwards, and briefly spiked in the early AD 1700s. This non‐convergence with the period of warfare recorded in the oral history, and the decline in frequency of the tool within the lithic assemblage, argues for an alternative interpretation. The results of previous experimental archaeology focusing on tool breakage patterns and micro‐wear studies, coupled to island deforestation, suggests that the tool had a role to play in forest clearance. 相似文献

The inter‐island Kula exchange network within the Massim region of eastern New Guinea is unique in its complexity, with the historically recorded configuration between the northern islands archaeologically visible between 1350 and 1500 AD (600–450 calBP). The southern islands were incorporated sometime later, and Tubetube Island formed a major hub in this southern extension of the Kula. To assess the timing and extent of Tubetube Islander involvement, excavated obsidian was used as a proxy to assess social connections with other island communities within the ambit of Kula. Forty‐nine pieces from two sites, Lagisuna and Tupwana, spanning the relevant period were chemically characterised using pXRF and determined to have been sourced almost exclusively from western and eastern Fergusson sources, respectively. We argue social connections between communities were village specific. Lagisuna had connections with the West Fergusson source region outside of the ethnographically known Kula network from 1500 to 1650 AD (450–300 calBP). Tupwana had maintained historically recorded kinship connections with important Kula communities on Duau and Dobu in the East Fergusson source region over several generations by at least 1800 AD (150 calBP), and probably intermittently from 1500 to 1650 AD. Our results support an increasingly nuanced model for the past development of Kula exchange. 相似文献
