摘要
由于长期埋藏,古代软玉文物中各种化学元素成分的变化是不可低估的关键因素。然而,日益严格的文物管理使得许多技术变得不切实际。因此,便携式 X 射线荧光(pXRF)已成为一种不可或缺的非破坏性现场分析方法。本文旨在利用 pXRF 数据集来区分所测试的元素是内源性元素还是外源性元素,以及判断哪些元素受到了较强的埋藏效应的影响。更具体地说,我们以南阳地区不同墓地出土的 103 件软玉为例开展这项工作。除了传统的统计技术外,一种新的工具--浓度-数量(C-N)分形法可以为分析出土软玉中不同元素的分布模式提供新的启示。该方法产生的异常边界具有明确的地球化学意义,可以划分出背景区和扰动区。评估了不同元素抵抗外部因素波动的程度,这与埋藏土壤的含量有直接关系。考虑到该模型的丰富性,它具有用于考古计量学的潜力。
Concentration-number (C-N) fractal models reveal the distribution pattern of the elements in ancient nephrite measured by portable X-ray fluorescence: Based on nephrite objects excavated from different sites in Nanyang, Henan Province
Changes in the composition of various chemical elements in ancient nephrite artifacts due to prolonged burial are critical factors that should not be underestimated. However, the increasingly stringent heritage management has made many techniques impractical. Consequently, portable X-ray fluorescence (pXRF) has become an indispensable nondestructive field analysis method. This paper aims to make use of the pXRF dataset to distinguish which elements tested are endogenous or exogenous, as well as to gauge which elements have been affected by stronger burial effects. More specifically, we carry out this work on the example of 103 pieces of nephrite excavated from different cemeteries in the Nanyang area. In addition to traditional statistical techniques, a new tool, the concentration-number (C-N) fractal method can shed new light on the analysis of the distribution patterns of different elements in excavated nephrite. The anomalous boundaries generated by the method have clear geochemical significance and can be delineated between background zone and disturbed regions. The degree of resistance of different elements to fluctuations in external factors was assessed, which has a direct relationship with the content of the buried soil. Considering the richness of the model, it has the potential to be used in archaeometrics.
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.
