Esr Dating of Pleistocene Hominid Sites, with Particular Reference to Europe, Western Asia and Africa: Continuation 2

该项目将继续并详细制定一项广泛的电子自旋共振(ESR)测年计划，旨在确定欧洲、西亚和南部非洲的重要地点的年龄，这些地点产生重要的原始人骨骼遗骸和/或反映更新世(或更老的)原始人种群不同适应和行为的职业。麦克马斯特大学(安大略省汉密尔顿)的这个ESR测年项目是北美唯一的此类项目。更新世人类骨骼样本和占领地点残留物的年龄测定对于各种正在进行的调查至关重要，这些调查旨在阐明人类进化生物学和系统发育的各个方面，过去的文化适应，地点间的相互关系，以及在时间描绘的框架内过去环境环境的演变。由于考古和古生物遗址中有丰富的骨骼/牙齿材料，ESR方法特别适用于许多重要的更新世事件，甚至可以追溯到几百万年前。该方法的精度约为%3-%5。该实验室已在欧洲和西亚以及初步在南部非洲的中、上更新世的各种情况下成功地应用了该方法，并为美国考古学家提供了重要的资源。

This project will continue and elaborate an extensive electron spin resonance (ESR) dating program directed toward age determination of significant sites in Europe, western Asia and southern Africa which yield important hominid skeletal remains and/or occupation occurrences reflecting varied adaptations and behaviors of Pleistocene (or still older) hominid populations. This ESR dating program at McMaster University (Hamilton, Ontario) is the only such operation of its kind in North America. Age determination of Pleistocene hominid skeletal samples and of residues of occupation sites is critical to diverse on-going investigations directed at the elucidation of aspects of hominid evolutionary biology and phylogenesis, past cultural adaptations, inter-site correlations and the evolution of past environmental circumstances in temporally-delineated frameworks. Due to the abundance of bone/dental material in archaeological and paleontological sites the ESR method is particularly applicable to many important Pleistocene occurrences, and for ages up to several million years ago. The precision of the method is approximately %3 - %5. The method has been increasingly successfully applied by this laboratory at a diversity of Middle and Upper Pleistocene situations in Europe and western Asia and, preliminarily, in southern Africa, and provides an important resource for US archaeologists.
