Kirigamine地区是日本中部关东地区黑岩的主要来源之一，被认为是一个重要的考古研究区域，旨在提高对旧石器时代晚期与黑岩采购活动相关的人与环境相互作用的历史变化的了解。以前的研究已经提出了人类活动与古环境之间关系的模型，但仍有必要基于与基里加明地区黑铁矿来源有关的数据来进一步了解。本研究旨在建立一种基于化学成分的黑铁矿人工制品的来源分析方法。用WDXRF和LA-ICPMS分析方法测定了基里加明地区13组黑麻岩来源的化学成分，并提出了判别图。为了核实的目的，使用这些辨别图对在Hiroppara史前遗址出土的黑铁矿文物的来源进行了分析。WDXRF和LA-ICPMS的来源分析结果是一致的，所描述的鉴别方法可以应用于进一步的无损EDXRF和pXRF分析以及微破坏性LA-ICPMS分析。
The Kirigamine area is one of the major obsidian sources in the Chubu-kanto region of central Japan, and is regarded as an important archaeological study area for improving the understanding of historical changes in human–environment interactions related to obsidian procurement activities during the Upper Paleolithic. Previous studies have presented a model for the relationship between human activities and the paleoenvironment, but there is a need for further understanding based on data related to the sourcing of obsidian in the Kirigamine area. This study aimed to establish a method for provenance analysis of obsidian artefacts based on chemical compositions. The chemical compositions of 13 groups of obsidian sources in the Kirigamine area were determined by WDXRF and LA–ICP–MS analyses, and discrimination diagrams proposed. For verification purposes, provenance analyses of obsidian artefacts excavated at the Hiroppara prehistoric site were undertaken using these discrimination diagrams. We yielded the same results of provenance analysis among the WDXRF and LA–ICP–MS methods, and the discrimination methods described may be applied to further provenance analysis of obsidian artefacts using nondestructive EDXRF and pXRF, and micro-destructive LA–ICP–MS analyses.
