Based on the study of the primary documentation related to the excavations carried out by Eurico Miller in the 1970s at Abrigo do Sol, Mato Grosso (Brazil), we propose a new reading of the stratigraphic and chronological information obtained from this rock shelter. Despite the apparent incongruity in the chrono-stratigraphic distribution of published dates, a detailed examination of the stratigraphy and field notes allowed us to identify a chronometric sequence with regular distribution between the Middle Holocene and the Late Pleistocene periods for the Abrigo do Sol site. We present here the original documents related to radiocarbon dating and their analysis. We finally show the implications of this study for understanding this site and the discussions related to the ancient settlements of the Amazon forest.

基于对 Eurico Miller 于 20 世纪 70 年代在马托格罗索州 Abrigo do Sol（巴西）进行的发掘相关的主要文献的研究，我们提出了对从这个岩石庇护所获得的地层和年代信息的新解读。尽管已发布日期的年代地层分布明显不一致，但对地层学和野外记录的详细检查使我们能够确定太阳阿布里戈遗址在中全新世和晚更新世时期之间规律分布的计时序列。我们在此介绍与放射性碳测年及其分析相关的原始文件。最后，我们展示了这项研究对于理解该遗址以及与亚马逊森林古代定居点相关的讨论的意义。
