Single and multielement archaeological geochemistry has been applied to research and rescue projects for many decades to enhance our understanding of the past use of space. Often applied on one contextual plane, this ignores the complex palimpsest resulting from past occupation and soil processes. Furthermore, many important sites are now heavily truncated by plowing, leaving little more than negative features below the homogenized topsoil. These challenges require new approaches to archaeological geochemistry to gather information before these sites are lost to modern land use. The research presented here applied coring as a sampling method on a truncated site, the sample locations guided by high‐resolution ground‐penetrating radar data and excavation, before using portable X‐ray fluorescence directly on the core samples to understand the phase by phase composition of the deposits and thus past human occupation. The results suggest that even in truncated and secondary contexts, such as the case study of the Viking Age trade settlement of Heimdalsjordet, Norway, archaeological geochemistry can give insight into the chronological and spatial development of the site, and is especially relevant for detecting nonferrous metalworking activity.

挪威Heimdalsjordet缩短的维京时代贸易结算的地球化学分析

数十年来，单元素和多元素考古地球化学已应用于研究和救援项目，以加深我们对过去空间利用的理解。通常将其应用在一个上下文平面上，它忽略了过去的占领和土壤过程所导致的最复杂的情​​况。此外，现在许多重要的耕地都因耕作而被严重截断，在均质的表土之下仅留下了负面特征。这些挑战要求采用新的考古地球化学方法来收集信息，然后再将这些地点遗失给现代土地使用。此处介绍的研究将取芯作为在截断现场的采样方法，采样位置由高分辨率的地面穿透雷达数据和挖掘指导，在直接在核心样品上使用便携式X射线荧光以了解沉积物的逐相组成以及过去的人类占领之前。结果表明，即使在截断和次要的情况下，例如挪威海姆达尔斯约德的维京时代贸易定居点的案例研究，考古地球化学也可以洞察该地点的时间和空间发展，尤其与检测有色金属加工相关活动。
