摘要

摘要本研究首次报道了从阿拉斯加中部Moose Creek（一个属于Nenana杂岩的组合）13000年前的占领中回收的文物的地球化学来源结果。在Nenana山谷的原材料调查中，我们发现了一个以前未被识别的英安岩来源，通过便携式X射线荧光，我们在这里介绍了它的地球化学。将该来源与Moose Creek组合中的人工制品进行地球化学比较表明，该遗址的Nenana杂岩居住者使用该原材料生产正式和非正式工具，包括一个诊断性的三角形Chindadn点。

Sourcing Dacite from the Nenana Complex Occupation at Moose Creek, Central Alaska

ABSTRACT This study reports the first results of geochemical sourcing of artifacts recovered from the 13,000-year-old occupation at Moose Creek in central Alaska, an assemblage assigned to the Nenana complex. During raw-material survey in the Nenana valley, we discovered a previously unrecognized source of dacite, and through portable X-ray fluorescence, here we present its geochemistry. Geochemical comparison of this source to artifacts in the Moose Creek assemblage indicates that the site’s Nenana-complex occupants used this raw material to produce both formal and informal tools, including a diagnostic triangular-shaped Chindadn point.

期刊介绍： PaleoAmerica disseminates new research results and ideas about early human dispersal and migrations, with a particular focus on the Americas. It fosters an interdisciplinary dialog between archaeologists, geneticists and other scientists investigating the dispersal of modern humans during the late Pleistocene. The journal has three goals: First and foremost, the journal is a vehicle for the presentation of new research results. Second, it includes editorials on special topics written by leaders in the field. Third, the journal solicits essays covering current debates in the field, the state of research in relevant disciplines, and summaries of new research findings in a particular region, for example Beringia, the Eastern Seaboard or the Southern Cone of South America. Although the journal’s focus is the peopling of the Americas, editorials and research essays also highlight the investigation of early human colonization of empty lands in other areas of the world. As techniques are developing so rapidly, work in other regions can be very relevant to the Americas, so the journal will publish research relating to other regions which has relevance to research on the Americas.
