ABSTRACT This paper presents a synthetic overview of the results of a multidisciplinary approach –archaeological, experimental and ethnographic – that provides new insights into the fire-related management strategies (from firewood procurement to fire use and cleaning activities) adopted by Yamana groups. We bring to the fore the significance of recent results from a chemical, GC-MS and GC-C-IRMS analysis of combustion residues recovered from Túnel VII and Lanashuaia I, two shell-midden excavated in the framework of several Spanish-Argentinean, Experimental Ethnoarchaeology projects developed in Tierra del Fuego Island (Argentina). The molecular and fatty acids isotopic composition allow characterizing the different combustion structures from the perspective of intensity or food processing, informing also about post-depositional factors. Results allow for a critical evaluation of ethnographic sources and thus of direct observation.

火地岛（阿根廷）南端狩猎-渔民-采集社会中与火灾相关的管理策略的实验民族考古学和分析方法

摘要 本文综合概述了多学科方法——考古学、实验和人种学——的结果，为 Yamana 集团采用的与火灾相关的管理策略（从木柴采购到火灾使用和清洁活动）提供了新的见解。我们突出了最近的化学、GC-MS 和 GC-C-IRMS 分析结果的重要性，该分析对从 Túnel VII 和 Lanashuaia I 中回收的燃烧残留物进行了分析，这些燃烧残留物是在几个西班牙-阿根廷人的框架内挖掘出来的，实验性在火地岛（阿根廷）开发的民族考古项目。分子和脂肪酸同位素组成允许从强度或食品加工的角度表征不同的燃烧结构，还可以了解沉积后的因素。
