Stable strontium isotope ratios in archaeological finds have frequently been used to determine their place of origin, in order to reconstruct migration and trade. Peat bogs offer favourable burial conditions for the preservation of organic remains such as woollen textiles and leather by a natural tanning process. However, these finds are impregnated by peat substances including contaminant strontium which is likely to mask the original (87)Sr/(86)Sr isotopic ratio of the specimens. In this paper, we present a pilot study analysing stable strontium isotopic ratios from Iron Age textile and leather finds from the Thorsberg peat bog, focusing on a sample processing method which permits the quantitative removal of contaminating strontium from the specimens.
考古发现中的稳定锶同位素比率经常被用于确定其起源地，以便重建迁移和贸易情况。泥炭沼泽为保存诸如羊毛纺织品和皮革等有机遗骸提供了有利的埋葬条件，通过自然鞣制过程实现保存。然而，这些发现物被包括污染物锶在内的泥炭物质所浸渍，这很可能掩盖标本原本的（87）Sr/（86）Sr同位素比率。在本文中，我们展示了一项初步研究，分析了来自托尔斯贝格泥炭沼泽的铁器时代纺织品和皮革发现物的稳定锶同位素比率，重点关注一种能够从标本中定量去除污染锶的样品处理方法。
