Abstract

Cherts originating from carbonate lacustrine environments have been widely exploited by Upper Palaeolithic hunter-gatherers in the south of the Pyrenees. Archaeo-petrographic sourcing studies have identified different potential sources but were unable to distinguish them. This study conducted geochemical characterisation of geological and archaeological lacustrine chert samples using laser-induced breakdown spectroscopy (LIBS), and applied the supervised classification model partial least squares–discriminant analysis to LIBS spectra. The model was able to discriminate geological sources and provide predictions for the origin of a selection of chert artefacts recovered at the Middle Magdalenian level from Cova del Parco (Lleida, Spain).

利用 LIBS 寻找 Chert 的来源：西班牙 Cova del Parco 案例

比利牛斯山脉南部的上旧石器时代狩猎采集者曾广泛开采过源于碳酸盐湖沼环境的石灰石。考古岩相来源研究发现了不同的潜在来源，但无法将它们区分开来。这项研究利用激光诱导击穿光谱（LIBS）对地质和考古湖沼石英石样本进行了地球化学特征描述，并将监督分类模型偏最小二乘判别分析应用于 LIBS 光谱。该模型能够区分地质来源，并对从 Cova del Parco（西班牙莱里达）出土的部分中马格达莱尼亚石器的来源进行预测。

期刊介绍： Archaeometry is an international research journal covering the application of the physical and biological sciences to archaeology, anthropology and art history. Topics covered include dating methods, artifact studies, mathematical methods, remote sensing techniques, conservation science, environmental reconstruction, biological anthropology and archaeological theory. Papers are expected to have a clear archaeological, anthropological or art historical context, be of the highest scientific standards, and to present data of international relevance. The journal is published on behalf of the Research Laboratory for Archaeology and the History of Art, Oxford University, in association with Gesellschaft für Naturwissenschaftliche Archäologie, ARCHAEOMETRIE, the Society for Archaeological Sciences (SAS), and Associazione Italian di Archeometria.
