摘要

Murujuga(也被称为丹皮尔群岛)位于西澳大利亚的西北海岸。它被列入澳大利亚国家遗产名录,因为它拥有大量重要的岩石艺术(雕刻/岩画),夹石工艺品和石头排列。了解自然景观与人的深层文化依恋之间的相互作用是滨海景观研究的焦点。为了更好地了解考古组合中石质人工制品的物源分布,我们通过现场地球化学分析研究了人工制品岩石类型的可行性。Murujuga的区域地质非常复杂,不同的岩石类型可能看起来很相似,这给正确识别带来了困难。对考古遗址附近的基岩样品进行了岩石学分析,以确定岩石的组成和结构特征。然后使用一个nion pXRF装置来定义地球化学特征。主成分分析强调了Zr和Ti作为区分当地岩石类型的关键鉴别器的有效性。然后,我们使用pXRF在迷迭香岛、海豚岛、北吉德利岛和Burrup半岛的Nganjarli (Deep Gorge)遗址分析了原位石制人工制品组合。我们的研究结果表明,大多数遗址的石制人工制品都来自当地的露头,除了在Nganjarli,在那里>;50%被定性为非本地。这些结果表明,pXRF是一种可行的技术,可用于对Murujuga人工制品组合进行原位分析,增加我们对这一富含工具石的环境中景观附着和人类流动性的理解。

Provenance analysis of stone artefact assemblages using petrography and pXRF at Murujuga (the Dampier Archipelago), Western Australia
Murujuga (also known as the Dampier Archipelago) is located on the northwestern coast of Western Australia. It is recognised on Australia’s National Heritage List for hosting extensive assemblages of significant rock art (engravings/petroglyphs), knapped stone artefacts and stone arrangements. Understanding the interactions between the natural landscape and people’s deep-time cultural attachment is a focal point for much research on this coastal landscape. To better understand the provenance distribution of stone artefacts in archaeological assemblages, we investigated the viability via in situ geochemical analysis by characterising artefact rock types in the field. The regional geology at Murujuga is very complex, and different rock types can appear similar, making correct identification difficult. A petrographic analysis was undertaken on bedrock samples near archaeological sites to define the rock’s composition and textural characteristics. A Niton pXRF device was then used to define geochemical characteristics. A principal component analysis was performed to highlight the usefulness of Zr and Ti as key discriminators for distinguishing between local rock types. We then analysed in situ stone artefact assemblages using pXRF at sites on Rosemary Island, Dolphin Island, North Gidley Island, and at Nganjarli (Deep Gorge) on the Burrup Peninsula. Our results show that stone artefacts from most sites were sourced from local outcrops, except at Nganjarli, where > 50 % were characterised as non-local. These results indicate that pXRF is a viable technique for in situ analysis of artefact assemblages at Murujuga, increasing our understanding of landscape attachment and human mobility in this tool-stone-rich environment.

期刊介绍: Journal of Archaeological Science: Reports is aimed at archaeologists and scientists engaged with the application of scientific techniques and methodologies to all areas of archaeology. The journal focuses on the results of the application of scientific methods to archaeological problems and debates. It will provide a forum for reviews and scientific debate of issues in scientific archaeology and their impact in the wider subject. Journal of Archaeological Science: Reports will publish papers of excellent archaeological science, with regional or wider interest. This will include case studies, reviews and short papers where an established scientific technique sheds light on archaeological questions and debates.
