The crystalline geological substratum of the Armorican Massif, in the West of France, is devoid of flint nodules in primary position. As a result, during Prehistory, humans developed different strategies for making their toolkits, either by adapting production methods to local rocks from diverse sources, or by importing materials from the sedimentary margins. This article proposes to analyse the distribution of lithic materials during the Mesolithic as the consequence of a succession of collective choices. Many sedimentary, metamorphic or plutonic rocks of local origin were used, and considerably increased in quantity from the Early Mesolithic to the Late Mesolithic. After the identification of the geological origin of the rocks, a series of mechanical analyses were carried out to define their properties. Then, the social integration process of these rocks was addressed. The lithic assemblages of Beg-er-Vil (Quiberon) and la Presqu’île (Brennilis) were then described to tangibly explain the intentions of productions in coastal and continental economies respectively during the Late Mesolithic (end of the seventh and sixth millennia BCE). The toolkits in both economies are strictly identical, but two different lithic management systems were clearly in place. The first, on the coast, consisted exclusively of production on pebbles, whereas, the other, inland, used a wide range of materials of mediocre quality. During the Mesolithic (and unlike Neolithic practices), and in this context of geological paucity, sacrificing technical standards always seemed preferable to long-distance acquisitions by means of imports or exchanges.

解释法国西部中石器时代岩石的转移

位于法国西部的 Armourican Massif 的结晶地质地层在主要位置没有燧石结核。因此,在史前时期,人类制定了不同的策略来制作他们的工具包,或者通过使生产方法适应来自不同来源的当地岩石,或者通过从沉积边缘进口材料。本文建议分析中石器时代石器物质的分布,这是一系列集体选择的结果。使用了许多当地起源的沉积岩、变质岩或深成岩,并且从中石器时代早期到中石器时代晚期,数量显着增加。在确定了岩石的地质起源后,进行了一系列力学分析以确定它们的性质。然后,这些岩石的社会整合过程得到了解决。然后描述了 Beg-er-Vil (Quiberon) 和 la Presqu'île (Brennilis) 的石器组合,以具体解释中石器时代晚期(公元前七千年和六千年末)沿海和大陆经济体的生产意图. 两个经济体的工具包完全相同,但显然有两个不同的管理系统。第一个是在海岸,完全由鹅卵石生产组成,而另一个是内陆,使用的材料范围很广,质量一般。在中石器时代(与新石器时代的做法不同),在这种地质稀缺的背景下,牺牲技术标准似乎总是比通过进口或交换的方式进行长途收购更可取。然后描述了 Beg-er-Vil (Quiberon) 和 la Presqu'île (Brennilis) 的石器组合,以具体解释中石器时代晚期(公元前七千年和六千年末)沿海和大陆经济体的生产意图. 两个经济体的工具包完全相同,但显然有两个不同的管理系统。第一个是在海岸,完全由鹅卵石生产组成,而另一个是内陆,使用的材料范围很广,质量一般。在中石器时代(与新石器时代的做法不同),在这种地质稀缺的背景下,牺牲技术标准似乎总是比通过进口或交换的方式进行长途收购更可取。然后描述了 Beg-er-Vil (Quiberon) 和 la Presqu'île (Brennilis) 的石器组合,以具体解释中石器时代晚期(公元前七千年和六千年末)沿海和大陆经济体的生产意图. 两个经济体的工具包完全相同,但显然有两个不同的管理系统。第一个是在海岸,完全由鹅卵石生产组成,而另一个是内陆,使用的材料范围很广,质量一般。在中石器时代(与新石器时代的做法不同),在这种地质稀缺的背景下,牺牲技术标准似乎总是比通过进口或交换的方式进行长途收购更可取。
