Abstract

In the Brazilian tropics, while débitage methods have generally undergone limited evolution, various solutions were sought to obtain tool blanks with controlled volumetric characteristics during the late Pleistocene and Holocene periods. One such solution was the unifacial shaping. It was particularly developed between 12,000 and 8000 BP in a vast area of central Brazil. It produced tools with varied functional potential. These unifacial pieces are found in a technical system where they are complemented by relatively standardized retouched flakes. This ensemble corresponds to what is known as the Itaparica Technocomplex, and emerged at a decisive moment in the densification of the region's population. Bipolar-on-anvil débitage is another facet of the technical solutions developed by prehistoric populations in Brazil. Although it receives less attention in the literature than other productions, it is nonetheless almost ubiquitous. Using a variety of methods, this débitage can be employed to produce a wide range of products, depending on the period and context. Recurrently, it is used to obtain medium to very small-sized products, whose functional purpose is not always well understood. These two examples illustrate the particularities of the technical history of Brazil's prehistoric populations. They highlight the choice of a different trajectory from that of their European contemporaries, who focused instead on the development of débitage concepts.

铁砧上的单面造型和双极切割:巴西史前的两个经典
在巴西的热带地区,虽然切割方法的发展通常有限,但在更新世晚期和全新世期间,人们一直在寻求不同的解决方案,以获得具有可控体积特性的工具支架。单面造型就是其中之一。特别是在公元前12000年到8000年之间,它在巴西中部的大片地区发展。它允许获得具有各种功能潜力的工具。这些单面部件是在一个技术系统中遇到的,在这个技术系统中,它们由相对标准的碎片工具补充。这一组对应于所谓的Itaparica技术综合体,出现在该地区人口密集的决定性时刻。铁砧上的双极切割是巴西史前人口开发的这些技术解决方案的另一个方面。在文学作品中,它没有其他作品那么突出,但它几乎无处不在。这种切割可以根据不同的时期和环境,使用不同的方法生产各种各样的产品。它经常被用于生产中型到非常小的产品,这些产品的功能用途还没有很好地确定。通过这两个例子,我们说明了巴西史前人口技术历史的特殊性。他们强调了与欧洲同时代人不同的道路选择,后者更多地依赖于切割概念的发展。在巴西热带地区,虽然切割方法的发展总体上是有限的,但在晚更新世和全新世期间,为了获得具有可控体积特征的工具空白,必须采用各种解决方案。= =地理= =根据美国人口普查,这个县的总面积是土地和水。= =地理= =根据美国人口普查局的数据,这个城镇的总面积,其中土地和(1.)水。它生产的工具具有多种功能潜力。失物招领These are unifacial room in a technical system或者they are complemented by relatively 362 retouched片。这一组与所谓的意大利技术综合体相对应,并在该地区人口密集的决定性时刻出现。双极铁轨切割是巴西史前人口开发的技术解决方案的另一个方面。虽然它在文学中受到的关注比其他作品少,但它几乎是无所不在的。使用多种方法,这种切割可以用于生产各种各样的产品,这取决于时期和背景。它通常用于获得中等到非常小的产品,其功能用途并不总是很清楚。这两个例子说明了巴西人口的技术历史的特点。他们强调选择一种不同的道路,而不是欧洲当代的道路,后者关注的是切肉概念的发展。
