The inter‐archipelago exchange of adzes after colonisation was not considered in the widely referred to culture historical Polynesian adze typology developed by New Zealand archaeologist, Roger Duff. This portable x‐ray fluorescence (pXRF) geochemical study re‐examined the assemblage of the adzes in museum collections that were classified into Duff Types by archaeologists Gonzalo Figueroa and Eduardo Sanchez. This paper investigates the geochemical patterning of the Polynesian basalt adze types found on the Pitcairn and Gambier Islands by (1) identifying volcanic rock type of the artefact (2) matching the geological sources used to make the artefacts using a Discriminant Function Analysis (DFA) and, (3) comparing an artefact's identified source to its recorded find spot. The results of the analyses conducted in this paper identified that 16 (8%) adzes had originated from different island groups than where they were collected from in the twentieth century. These adze exchanges provide more evidence of long‐distance Polynesian connections that occurred after people initially colonised central east Polynesia and thus further refutes the idea that these islands were occupied in isolation – a critical re‐evaluation of Duff's typology is therefore required.

Duff的adze类型学与波利尼西亚的adze交流

新西兰考古学家罗杰·达夫(Roger Duff)开发的被广泛提及的文化历史波利尼西亚ad子类型学中,并未考虑到殖民后弧菌之间的ad子交换。这项便携式的X射线荧光(pXRF)地球化学研究重新检查了博物馆收藏品中的各种装饰品,这些收藏品被考古学家Gonzalo Figueroa和Eduardo Sanchez分类为Duff类型。本文通过(1)识别人工制品的火山岩类型(2)与判别函数分析(DFA)匹配用于制造人工制品的地质来源,调查了在皮特凯恩岛和甘比尔群岛上发现的波利尼西亚玄武岩类型的地球化学模式。 (3)将人工制品的识别出的来源与其记录的发现地点进行比较。本文进行的分析结果确定,与二十世纪相比,来自不同岛屿群的热潮有16个(8%)。这些相互交流的交流提供了人们最初在波利尼西亚中部东部殖民之后发生的长距离波利尼西亚联系的更多证据,因此进一步驳斥了这些岛屿被孤立占领的想法–因此,需要对达夫的类型学进行重新评估。
