Based on ethnographic accounts from the eighteenth to the twentieth century, functional areas have been identified within
Fueginian shell middens. In this context, archaeological microfacies acquire a functional meaning when the microscopic record
is compared to information gathered from ethnology, macroscopic observations made during excavation, and experimental modern
analogues. All these lines of evidence were combined for the first time at Tunel VII, an eighteenth/nineteenth century shell
midden occupied repeatedly by Yamana people, the last hunter–gatherer–fisher groups of the Beagle Channel. The sampling strategy involved three sets of samples:
(1) two stratigraphical columns taken from the hut “entrance” and from a portion of the shell midden (i.e., the surrounding
refuse shell ring), (2) thin sections from five hearths representing successive phases of frequentation of the hut, and (3)
experimental burnt valves of Mytilus edulis, the main malacological component of the site. Comparison of microfacies from groups (1) and (2) provided microscopic indicators
to distinguish between shell dumping areas and occupation surfaces. Comparison of microfacies within columns from group (1)
allowed recognizing periods of site abandonment and periods of more intense/longer site frequentation. The experimental samples
from M. edulis served as a reference to characterize the five central hearths in terms of maximum burning temperatures reached. Different
burning structures were correlated to the season of hut frequentation and to their location (and function) within different
portions of the hut. The intra-site micromorphological comparison strategy within a well-documented ethnohistorical context
provides valuable indicators for the identification of functional areas in archaeological contexts when ethnographical information
is not available. 相似文献

This study is focused on the El Milagro mine (Asturias, Spain) and is part of a large‐scale effort on the measurement of the lead isotopic composition of Spanish copper ores from prehistoric mines in the provinces of Asturias and León, from which no data were available until recently. Lead isotopic values are compared to the published lead data from the El Aramo mine in the same region. The results show that both mines have a very similar lead isotopic composition, apart from some highly radiogenic samples in the El Milagro mine, which are clearly different from those previously reported for the Iberian Peninsula. 相似文献
