U-Pb dating of zircon: A sourcing method for pottery from La Morena archaeological site,north-west Colombia*

U-Pb zircon radiometric dating and petrographic thin-section analysis were used for provenance identification of Ferrería and Marrón Inciso pottery styles from La Morena archaeological site in northwestern Colombia. U-Pb dating was applied to zircons recovered from pottery and rock samples from nearby geological units. The results suggest at least three distinct sources: the metamorphic rock unit on which the archaeological site is located, a granodiorite unit that outcrops further away from the site, and a mafic rock that cannot be attributed with certainty. U-Pb in zircons proved to be effective as a provenance method, where ages of the possible source rocks are well constrained, and can be applied to areas where traditional sourcing methods may be problematic.     

Traces of Early Austronesian Expansion to East Indonesia? New Discovery of Dentate-Stamped and Lime-Infilled Pottery from Central Sulawesi

This short article report about the new findings of finely made dentate-stamped and lime infilled potteries from the Goa Topogaro site in Central Sulawesi, Indonesia. Most of them are red-slipped pottery decorated with dentate-stamped, lime infilled, and can be identified as burial potteries as they are excavated with secondly burials of the Early Metal Age possibly dated around 2000-1800 years ago. When comparing these finds with common decorative patterns seen in early dentate-stamped pottery assemblages in the Philippines, Mariana Islands, and early Lapita sites, the Topogaro dentate-stamped pots lack some common early patterns, but exhibit a wider variety of designs. It is now argued that dentate-stamped decorations at Lapita sites mainly disappeared by around 2800 BP or at least by 2000 BP in the Pacific, but the Topogaro dentate-stamped sherds may indicate that this pottery tradition continued and further developed in Island Southeast Asia or Sulawesi at least until the Early Metal Age. The detailed analysis of these new finds and further comparative study on production technique, variety of design, forms, and styles of both dentate-stamped ceramics in Southeast Asia and Oceania is required.     

Provenance of Weeden Island “sacred” and “prestige” vessels: implications for specialized ritual craft production

ABSTRACT

Weeden Island mortuary ceremonialism united distinct cultures across the Late Woodland social landscape. The Weeden Island pottery series is central to recognizing regional ceremonial parity, with prestige (elite) and sacred (cult) wares showing strong similarities among distant sites. Finely made vessels and their ostensibly shamanistic themes led archaeologists to consider the liturgical and political roles of ritual specialists, whose tasks might have included vessel manufacture in centralized locations. This research evaluates the prospect of craft specialization and centralized production of sacred and prestige wares through comparisons of the provenance of vessels from three Florida localities: Palmetto Mound (8LV2), the mounds at Melton (8AL5, 8AL7), and McKeithen (8CO17). Results of Neutron Activation Analysis and petrographic analysis show that the majority of the sampled vessels were made far from the mounds in which they were deposited, from a variety of locations but especially within the area between Kolomoki and the Tallahassee Hills. We argue that production was not centralized but may have been specialized to the extent that an integrated ritual network was necessary to coordinate rules of manufacture and use that were evidently observed by all participants.     

河南信阳城阳城遗址战国楚墓出土彩绘陶器的科学研究

为研究河南信阳城阳城址战国楚墓出土彩绘陶器病害,采用X荧光光谱分析、红外光谱分析和拉曼光谱分析对陶器表面颜料、有机底层、金属涂层进行了分析检测,并对陶胎物理性能进行了分析。研究发现:这批城阳城址彩绘陶器为高硅低铝陶器,为典型北方灰陶类型,吸水率较大,结构比较疏松,烧成温度范围在930℃～1025℃。陶器表面红色颜料主要为朱砂和赤铁矿,黄色颜料为针铁矿; 8号墓部分彩绘陶器彩绘层底含锡; 18号墓彩绘陶器黑褐色有机底层为生漆,为漆衣彩绘陶。这些信息为保护修复方案设计和保护修复实施提供了科学基础。     

西安市南郊马腾空唐墓发掘简报

2001年4月至10月间,我们在西安市南郊马腾空清理了15座唐代墓葬。所有墓葬皆为南北向,单室墓室,墓道在南,墓室居北。墓葬形制可分为A、B、C三型。可以看清的几例葬具、葬式皆为单棺单人,仰身直肢。随葬品以陶俑最为丰富,计有镇墓俑、男俑、女俑、动物俑等,其中男俑、女俑的中的半身俑时代特征明显,女俑的发式新颖奇特,造型生动,在隋唐考古中较为少见。加之又出土了四盒墓志,具有明确的纪年,可以作为判断其年代的标形器。这批墓葬的发掘为关中地区唐墓谱系的建立增加了新资料,同时对其它地区唐墓的研究也有借鉴作用。     

殷墟仿铜陶礼器墓试析

殷墟四期偏晚阶段出现仿铜陶礼器墓,其器物组合较固定,所含器类较全,学者对其认识不一。作者认为其出现有深刻的社会原因,同时又和人们的意识形态、思想变化密不可分,是人们对资源利用观念的一种转变。     

Imperial Expansion, Ethnic Change, and Ceramic Traditions in The Southern Chad Basin: A Terminal Nineteenth-Century Pottery Assemblage from Dikwa, Borno State, Nigeria

In the course of an archaeological project in the southern Chad Basin of Nigeria, excavations were conducted at several deeply stratified mound sites that date from the Late Neolithic to the Late Iron Age. As a way to complement the ceramic sequence obtained so far and to link it with today's pottery tradition, a small excavation was conducted at a site that dates to the turn of the nineteenth to the twentieth century A.D. A pottery assemblage was discovered that shows obvious links to today's tradition but notable breaks with those of the nineteenth century and earlier. This break in decoration style and technique is interpreted as an archaeologically visible expression of changing ethnic identity. This ethnic change and the associated spread of the ceramic tradition can be linked with the expansion of the sphere of power of the Kanem-Borno Empire into the area south of Lake Chad after the sixteenth century A.D.     

I Want to Buy a Black Pot

Cooking pots made by craft specialists in a neighborhood in a small city in the Philippines are hand made, using the paddle and anvil technique, and then slipped with an iron-rich clay and polished with a marine shell. They are fired in an open fire, removed while very hot, and immersed in a bed of rice chaff. The result is a shiny black pot that is easily recognized in the market as being the product of this neighborhood. Such pots are valued by consumers as more beautiful and durable compared with pots made elsewhere. To see if the iron and carbon surface treatments improve the performance of the cooking pots, 50 pots were commissioned, with surfaces that varied from no treatment to slip only or carbon only as well as both carbon and slip. This collection was tested at the University of Arizona, and results clearly indicate that heating effectiveness is improved with both slip and carbon present. The surface treatments of red slip and smudge also affect the performance of pots for water permeability. However, our tests show no obvious relationships between strength and different surface treatments. The project illustrates the power of combining ethnoarchaeology with experimental studies in understanding artifact design.     

贾湖遗址出土古陶产地的初步研究

利用等离子体发射光谱 (ICP),对舞阳贾湖遗址出土古陶样品进行了常量元素和微量－痕量元素的测试分析,结合考古发掘资料和考古学分析,采用聚类分析方法,系统研究了贾湖遗址出土古陶的矿料来源,发现贾湖制陶业基本处于家庭制陶阶段。本文还将贾湖遗址与大河村遗址和西山遗址的出土古陶产地进行了比较研究。结果表明,这些遗址的陶器在聚类分析谱系图上被明显地分为相应的三类,它暗示上述三处遗址间无明显文化交流关系。     

West African Tradition in the Decoration of Colonial Jamaican Folk Pottery

In the early colonial period, Jamaican slaves manufactured pottery that incorporated traditional West African technology with selected European innovations. Recent examination of Afro-Jamaican wares from the seventeenth-century site of Port Royal suggests that the decorative elements are consistent with those that are in wide use among West African pottery traditions, particularly those of the Gold Coast (Ghana). Stamped designs prevail as the clearest example of this continuity. Potential Amerindian contributions to the Jamaican folk pottery industry during this period are considered and shown to be unlikely. The isolation of decorative traits demonstrates how certain craft elements of West African peoples were transported to the New World and integrated with other cultural traditions. It also corroborates the documentary record pertaining to the geographical origin of Jamaican slaves during the early colonial period.
