Abstract

ABSTRACT Two major criteria for judging the validity of claims for early settlement of the Americas are solid dating by radiometric methods and evidence of stratigraphic integrity. Luminescence dating can provide information on both, not only producing a date but evaluating stratigraphic integrity by means of single-grain dating. Because of these qualities, luminescence has been applied to a large number of early sites. This paper reviews these applications, both for sites in which stratigraphic integrity has been shown and for sites where it has not. Two recent applications, at Parson’s Island in Maryland and at Bastos in Brazil, suggest settlement may have been as early as the Last Glacial Maximum.

沉积物的发光定年对了解美洲第一次定居的贡献

判断美洲早期人类定居主张有效性的两个主要标准是通过辐射测定法确定年代和地层完整性证据。发光测年可以提供这两方面的信息，不仅可以产生年代，还可以通过单粒测年来评估地层的完整性。由于这些特性，发光已被应用于大量的早期位置。本文回顾了这些应用，包括已显示地层完整性的地点和未显示地层完整性的地点。最近在马里兰州帕森岛(Parson’s Island)和巴西巴斯托斯(Bastos)进行的两项研究表明，人类可能早在末次盛冰期(Last Glacial Maximum)就开始定居了。

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.
