Abstract

Fingerprinting of iron-rich natural pigments commonly known as ochre, provides the opportunity to trace the cultural movement of these ochres in the archaeological past. This manuscript presents a proof-of-concept approach to the analysis and characterisation of ochre deposits, through the application of magnetic analytical methods. The use of measurements such as room temperature – saturation isothermal remnant magnetisation (RT-SIRM), isothermal magnetisation sweeps (hysteresis loops) and zero-field-cooled/field-cooled (ZFC-FC) remanence allow for the identification of a magnetic mineral profile in the ochre samples, which can, in turn, be used to fingerprint sources. Using low-temperature remanence and hysteresis measurements, we have demonstrated the ability to discriminate between geological contexts and thereby contribute to the greater goal of tracing cultural exchange via the movement of ochre from their original sources.

一种利用矿物磁测量指纹识别赭石源的新方法

通常被称为赭石的富含铁的天然颜料的指纹，提供了在考古过去追踪这些赭石的文化运动的机会。这份手稿提出了一个概念验证的方法来分析和表征赭石矿床，通过应用磁分析方法。使用诸如室温-饱和等温残余磁化（RT-SIRM），等温磁化扫描（磁滞回线）和零场冷却/场冷却（ZFC-FC）剩余物等测量方法，可以识别赭石样品中的磁性矿物剖面，进而可用于指纹源。利用低温残余和迟滞测量，我们已经证明了区分地质背景的能力，从而有助于通过赭石从其原始来源的移动来追踪文化交流的更大目标。

期刊介绍： The Journal of Archaeological Science is aimed at archaeologists and scientists with particular interests in advancing the development and application of scientific techniques and methodologies to all areas of archaeology. This established monthly journal publishes focus articles, original research papers and major review articles, of wide archaeological significance. The journal provides an international forum for archaeologists and scientists from widely different scientific backgrounds who share a common interest in developing and applying scientific methods to inform major debates through improving the quality and reliability of scientific information derived from archaeological research.
