Determination of Chert Sources of Pre-Historic Artifacts, Northwestern Alaska

9317327阿什利对石器的高级岩石学和地球化学分析为解决有关史前社会的问题提供了独特的机会，包括最早的美国人的迁徙和贸易路线。本论文主要研究阿拉斯加西北部史前遗迹中的硅质岩露头及其岩石学和地球化学特征与硅质岩人工制品的相关性。将使用显微镜、矿物包裹体电子探针分析和微化石鉴定进行岩石学对比。地球化学对比将基于痕量元素的中子活化分析的统计结果。***

9317327 ASHLEY Advanced petrological and geochemical analysis of stone artifacts provides a unique opportunity for resolving questions about prehistoric societies, including migration and trading routes by the earliest Americans. This dissertation research will focus on the study of chert outcrops and the correlation of their petrological and geochemical signatures with those of chert artifacts from prehistoric sites in northwest Alaska. The petrological correlation will be made using microscopy, electron microprobe analysis of mineral inclusions and microfossil identification. The geochemical correlation will be based on statistical results of neutron activation analysis of trace elements. ***
