Abstract

ABSTRACT Late Pleistocene human occupations are well represented in the Tandilia Range, Argentine Pampas. Abrigo 1 is a small shelter in close relation to the main and better-known site on the hilltop of Cerro El Sombrero, with both sites including Fishtail points. The oldest levels at the shelter dated to 13,000–12,000 calendar years ago and yielded two Fishtail points. This paper deals with the analysis of the sedimentary context, stratigraphy, artifact distribution, and site formation processes at Abrigo 1. The sedimentary record is dominantly composed of geogenic sediments with a minor participation of anthropogenic material, mainly lithic artifacts. The geogenic input includes sediments coming from the physical and chemical weathering of the rockshelter’s quartzites and windblown sediments. Pedogenesis is the prevailing site formation process. Artifact distribution, the homogeneity of the assemblage, and refitting are considered relevant to assess site integrity. The results are compared to other early cultural contexts of the immediate vicinity.

外套1，塞罗·埃尔·帽子：阿根廷东部的一个早期遗址

阿根廷潘帕斯的坦迪利亚山脉是晚更新世人类活动的典型代表。Abrigo 1是一个小型避难所，与Cerro El Sombrero山顶上的主要和更著名的地点密切相关，两个地点都有鱼尾点。该避难所最古老的水平可追溯到13000 - 12000日历年前，并产生了两个鱼尾点。本文对Abrigo 1的沉积环境、地层、人工制品分布和遗址形成过程进行了分析。沉积记录以地质沉积为主，少量人为物质参与，主要是石器制品。地质输入包括来自岩穴石英岩的物理和化学风化和风吹沉积物的沉积物。成土作用是主要的立地形成过程。人工制品的分布、组合的同质性和重新装修被认为与评估遗址的完整性有关。研究结果与邻近地区的其他早期文化背景进行了比较。

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.
