Obsidian sources and distribution systems in Island Southeast Asia: new results and implications from geochemical research using LA-ICPMS

This paper discusses new evidence of long-distance interaction networks in Island Southeast Asia obtained from geochemical analyses using SEM-EDXA and LA-ICPMS of 101 obsidian samples from 25 locations including seven obsidian sources and 19 archaeological sites. Given that there are obsidian sources distributed throughout much of Island Southeast Asia, the potential for obsidian studies to provide greater understanding of patterns of mobility and exchange in the Pre-Neolithic and Neolithic periods would seem to be considerable. This potential, however, remains largely unrealised as obsidian sourcing has hitherto only been carried out intermittently in Island Southeast Asia using PIXE-PIGME, XRF and other methods.     

Obsidian provenance studies in Colombia and Ecuador: obsidian sources revisited

The field occurrences, elemental compositions and formation ages of Colombian and Ecuadorian obsidians are revisited. It is shown that the regional sources of this raw material are linked to two major volcanic structures: the Chacana and the Paletara calderas, localised on the eastern cordillera of Ecuador and on the central Andean cordillera of south Colombia respectively. Seventy-two samples were analysed by inductively coupled plasma-atomic emission spectroscopy (ICP-AES), inductively coupled plasma-mass spectrometry (ICP-MS) and/or particle induced X-ray emission (PIXE). The same 10 types of elemental compositions were identified independently from ICP and PIXE. Four of these types were previously unknown. The formation ages of these obsidians previously determined by fission tracks dating are in the range 0.17–1.58 Ma at Chacana and 3.46–4.27 Ma at Paletara. Most Colombian and Ecuadorian pre-Hispanic artefacts present elemental compositions compatible with a Chacana- or Paletara-derived origin of the raw material. However, some of them present fission track ages discordant with the present-day known obsidian occurrences, which implies that the regional source inventory is not yet exhaustive.     

From flow to quarry: magnetic properties of obsidian and changing the scale of archaeological sourcing

Previous studies have endeavored to use petrophysical traits of obsidian, particularly its magnetic properties, as an alternative to conventional geochemical sourcing, one of the greatest successes in archaeological science. Magnetic approaches, however, have not seen widespread application due to their mixed successes. In a time when geochemical analyses can be conducted non-destructively, in the field, and in a minute or two, magnetic measurements of obsidian must offer novel archaeological insights to be worthwhile, not merely act as a less successful version of geochemistry. To this end, we report the findings of our large-scale study of obsidian magnetism, which includes 734 geological obsidian specimens and 97 artifacts measured for six simple magnetic parameters. Based on our results, we propose, rather than using magnetic properties to source artifacts to a particular obsidian flow (inter-flow sourcing), these properties are best used to differentiate quarrying sites within an individual flow (intra-flow sourcing). Our results also demonstrate that certain magnetic properties are highly affected by ancient knappers' material selection criteria. Furthermore, depending on the spatial scales of variation, which likely vary from flow to flow, we envision several potential applications of this approach, including integration into minimum analytical nodule analysis (MANA). Magnetic data appear to shift the scale of obsidian sourcing from flows to quarries and, in turn, enable new insights into raw-material procurement strategies, group mobility, lithic technology, and the organization of space and production.     

Obsidian sources in highland Yemen and their relevance to archaeological research in the Red Sea region

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.     

The prehistory of Island Southeast Asia: A multidisciplinary review of recent research

Island Southeast Asia extends across both the equatorial and the intermediate tropical zones of world climate, and it also spans a region of complex and geologically unstable land and sea relationships. The Sundaland region in the west and the isolated islands of Wallacea in the east both witnessed complex trajectories of human movement and evolution during the Pleistocene. The record of human evolution in Sundaland is still affected by uncertainties over phylogeny, dates, and archaeological correlations. Initial human settlement across Huxley's Line into Wallacea cannot at present be proven to be older than the Late Pleistocene. Stone tool industries dating to within the past 40,000 years are described, including new discoveries which indicate a surprising level of technological virtuosity. Human populations of the Late Pleistocene and Holocene are also considered in terms of skeletal and genetic data, particularly with respect to the rather controversial antecedents of the present, mainly Mongoloid, population. The article terminates its coverage at about 2000 B.C., within the period characterized by the expansion of speakers of Austronesian languages and by the expansion of agriculture into a porous and often-resistant network of hunter-gatherer societies. The archaeological and ethnographic records of the region bear witness to a continuous but dwindling existence of hunting and gathering right through to the present day. While the results of archaeology occupy a central position in the reconstruction of Southeast Asian prehistory, a proper understanding can be achieved only if a multidisciplinary standpoint is adopted.

A review of archaeology in mainland Southeast Asia

This article outlines recent advances in establishing and understanding the prehistoric sequence in mainland Southeast Asia. Research has been unevenly distributed, varying from virtually none in Cambodia to a marked intensity in Hong Kong and the adjoining mainland. A new pattern is becoming apparent, due in no small part to the new findings in southern China. It is argued that despite its long history of occupation, beginning withHomo erectus almost a million years ago, tropical Southeast Asia was occupied by scattered inland groups and larger, possibly sedentary coastal foragers until exposed to intrusive agricultural societies during the third millennium BC. These communities, which originated ultimately in the Yangzi Valley, brought with them rice cultivation and were responsible for the wide distribution of Austroasiatic languages. The three divisions of this language superfamily are now distributed from eastern India to southern China. Following a relatively brief Neolithic period, small and autonomous communities, particularly in Lingnan and Bac Bo (Guangdong and Guangxi provinces of China and the area of the Red River Delta), were exposed to exchange contact with the Shang state of the Chinese Central Plains, and this brought exotic jades and bronzes. Within this context, a local bronze industry was established between 1500 and 1000 BC over much of Southeast Asia, but without any obvious social developments until the middle of the first millennium BC, when several major changes occurred. These incorporated iron smelting and forging and exposure in the southern parts of the region to Indian mercantile contact and along the northern margins to the expanding Chinese empire. Adaptations varied regionally, from the establishment of warrior chiefdoms to counter the Chinese to the construction of water control systems in the arid heart of Southeast Asia to alleviate environmental unpredictability. It is within these regional changes that we can identify trends toward the establishment of states, some of which persisted in an unbroken lineage to the present.     

Obsidian source characterization in the Cordillera Real and eastern piedmont of the north Ecuadorian Andes

Recent research in the Quijos and Cosanga valleys of the eastern piedmont of Ecuador’s Cordillera Real has revealed and substantiated previous knowledge of obsidian sources that are unrelated to obsidian flow systems in the Sierra de Guamaní, Ecuador. Neutron Activation Analysis (NAA) and X-ray Fluorescence (XRF) were carried out on 47 obsidian source samples collected from several contexts in and adjacent to the study area. From samples within the study area three distinct obsidians were characterized: Cosanga A, Cosanga B, and Bermejo. These obsidians originate from a number of obsidian-bearing rhyolitic domes recently identified in the hills west of the Río Cosanga. Extensive survey of these dome localities has identified obsidian cobbles large enough for formal and informal tool manufacture. Beyond the study area, samples were collected and analyzed from the El Tablón source in the Sierra de Guamaní, providing much needed data on this poorly understood source. In addition, a sample from the newly identified Conda Dome source, near the Cotopaxi volcano, was characterized with XRF. All samples were then compared to 57 pre-existing samples from the Mullumica–Callejones, Yanaurco–Quiscatola and Carboncillo sources in the Ecuadoran Cordillera Real, as well as to artifacts from the Sumaco area in the Ecuadorian Amazon. Results of the elemental characterization indicate that the Cosanga Valley, El Tablón and Conda Dome obsidians are chemically distinct. Further, visual characteristics of Cosanga Valley obsidian types are useful in source attribution for the large artifact samples from the region. Finally, obsidian collected from the El Tablón flow suggests that this source may have produced obsidian suitable for tool manufacture.

Spaces of labour control: comparative perspectives from Southeast Asia

This paper seeks to identify the spatialized dimensions of labour control in sites of rapid and recent industrialization in Southeast Asia. Using a comparative analysis of locations in Penang (Malaysia), Batam (Indonesia) and Cavite/Laguna (the Philippines), it is argued that the construction and control of space has been used to enhance control over the working body, and, in particular, to contain labour organization, unionization and collective bargaining. Three broader arguments are made. First, that labour geographies need to be cognizant of the spatialized politics of labour beyond a narrow focus on the trade union movement. Second, that space is a potent tool in labour control and must be explicitly considered alongside the identity–based control strategies and institutional structures that have usually informed studies of labour regimes in newly industrializing contexts. Finally, a comparative perspective on local labour markets, and control regimes in particular, shows that the ways in which space is constructed and controlled differs between contexts, implying that universal judgements on the relevance or importance of particular arenas or spaces for labour politics should be reserved.     

The Transition to History in Southeast Asia: An Introduction

Studies of the transition from prehistory to history in Southeast Asia have traditionally relied primarily on documentary sources, which tend to emphasize foreign influences, rather than on the archaeological record, which suggests a series of indigenous developments. The papers in this journal issue and the next discuss strategies for using both documentary and archaeological evidence to study the transition to history and the emergence of early states in the region. These papers investigate how political units were structured and integrated in Cambodia, Thailand, Malaysia, the Philippines, and South China, and illustrate how historical and archaeological data can cross-check each other to inform on Southeast Asian sociopolitical and economic developments during the early historic period.     

郑和下西洋与东南亚华侨华人

根据笔者实地考察,东南亚至少有15个郑和寺庙和近30个有关郑和的传说。它们反映了早期南洋中国移民的生活状况、他们与当地妇女的通婚、华侨宗教信仰的特点以及华侨华人在中外文化交流中所发挥的重要的桥梁作用。东南亚华人纪念郑和活动的特点是“四个结合”,即将纪念郑和与继承中华传统文化、吸收定居国文化相结合,与宣扬祖籍国和定居国的友好关系相结合,与发扬华人创业精神相结合以及与争取华族正当权益、促进族群和睦、繁荣当地经济相结合。虽然郑和在东南亚影响很大,但海外对郑和的了解仍十分有限,因此,在海外全面、深入地介绍郑和任重而道远。

Field anthropology: application to burial contexts in prehistoric Southeast Asia

The context of burials in archaeological sites, that is whether the body was inhumed, wrapped, or in a coffin, is an aspect of mortuary ritual that has been missing from English-language publications on the subject. This is despite the development and use in France over at least the last two decades of methods of determining the context under the rubric ‘l'Anthropologie de Terrain’, or Field Anthropology. This paper briefly reviews the methods and applies them to prehistoric burial samples from two sites in Southeast Asia. This shows that burials at the Bronze Age site of Ban Lum Khao were either in coffins or wrapped. The practice of coffin burial appears to have been abandoned later, as all burials at the nearby Iron Age site of Noen U-Loke were wrapped.     

The ethics, politics, and realities of maritime archaeology in Southeast Asia

There is a constant battle between maritime archaeologists and commercial salvors throughout the world. In many developed countries, the arguments of archaeologists are valid, and their actions fully justify their stance. This is not so in Southeast Asia. In this region, archaeological information is being lost on a massive scale. Co-operation between the two groups, and with regional governments, is essential to prevent more irreparable damage.     

The privatisation of maritime security in Southeast Asia: the impact on regional security cooperation

This paper examines the involvement of new modes of governance (NMoG)/new actors, in establishing new regional regulatory frameworks in Southeast Asia. The basis for this discussion is a framework suggested by Kanishka Jayasuriya who argues that the activities of NMoG can facilitate the establishment of such regional regulatory frameworks. Concentrating on maritime services provided by one new actor, Private Military and Security Companies (PMSCs), this paper suggests that the current activities and working practices of PMSCs in Southeast Asia are more likely to undermine regional security cooperation and regional governance, thus challenging some of the tenets of Jayasuriya's framework.     

东南亚地区农业起源研究综论

自20世纪50年代始,东南亚地区的农业起源探索历程至今已半个多世纪。大量考古发现表明,东南亚早期农业的性质是依赖于根系作物的驯化和块茎作物的栽培,该地区早期农业的特点与树木栽培的实践紧密相连,但农业起源的时间尺度仍未很好地建立。基于东南亚地区植物遗存和农业性质的特殊性,多种研究方法得以运用,也相继提出了许多不同的理念。东南亚地区农业起源的研究对中国华南地区早期农业的探索具有很好的启示作用。     

浅析东南亚地区出土(水)的龙泉青瓷——遗址概况、分期及相关问题分析

近年来在东南亚地区的一些陆地遗址以及相关海域的沉船遗址中发现了数量颇多的龙泉青瓷,年代从南宋早期延续到明代中期。龙泉青瓷器在东南亚地区的发现一定程度上反映了历史上龙泉青瓷器对该地输出的情况。东南亚地区出土(水)龙泉青瓷器器形有碗、盘、洗、瓶、香炉、罐、梅瓶、高足杯、盆、盒、壶、匜等,其中以碗、盘、罐较为多见,在当地主要的用途为:生活用器、祭器、随葬用器、葬具和陈设器等。龙泉青瓷大量外销东南亚地区,对当地的制瓷手工业产生了很大的影响。     

东南亚华商与经济民族主义

在经济全球化的大潮中,东南亚华商面对居住国“原住民优先”政策的压力、民族主义情绪的高涨和对立,应该立足于各自国家的立场和根本利益,与各自国家的其他族裔加强合作,共谋发展,实现互利共赢。这是东南亚华商的唯一出路,也是化解东南亚国家原住民经济民族主义的正确途径。东南亚华商只有随着本国国民经济的发展才能获得自身发展的机会,不可能存在超越国家利益之外的所谓海外华人的利益。
