Carbonized fruits and seeds from two recently investigated Iron Age hilltop settlements, one located north and the other south of the main Alpine range, were analyzed and reveal a detailed insight in the subsistence strategies of the Eastern Alps. The results were compared with archaeobotanical data sets from other Iron Age excavation sites in Austria, Eastern Switzerland and Northern Italy. On the basis of variable data from 17 sites it is not possible to detect a geographical pattern through statistical analyses. On the basis of the frequencies, however, it becomes clear that the principal cereals were Hordeum vulgare (hulled six-rowed barley), Triticum dicoccon and T. spelta (emmer and spelt) and Panicum miliaceum (broomcorn millet). In addition, foxtail millet (Setaria italica) as well as naked wheat played some role. Legumes such as Vicia faba (horse bean) and Pisum sativum (pea) also occurred regularly and supplemented the diet of the prehistoric settlers. More systematic research with standardized methods is however urgently needed to corroborate the existing data. 相似文献

The impact of mining activities on the environment reflected by pollen,charcoal and geochemical analyses 总被引:1,自引:0,他引:1

This article presents results of a multi-proxy study of a fen deposit in the former mining district of Falkenstein near Schwaz in the Tyrol, Austria. The aim of the study in the framework of the special research program HiMAT (The History of Mining Activities in the Tyrol and Adjacent Areas – Impact on Environment & Human Societies) was to disclose the ecological impact of mining in pollen and heavy metal diagrams and to create a model combining the changes in palaeoecological proxies with historical evidences for mining. The application of this palaeoecological–historical model to prehistoric times allowed us to reconstruct the impact of mining and metallurgic activities in the surroundings of the fen during the last millennia. The results of stratigraphy, radiocarbon dating, LOI, pollen and micro-charcoal analyses as well as geochemical analyses of scandium, lead and lead isotopes validated by historical and archaeological data are hereby presented. 相似文献

In September 1994, an eruption of the Rabaul Volcano in East New Britain, Papua New Guinea, devastated the town of Rabaul and many surrounding Tolai villages. Many villagers were resettled or lived in refugee camps far from their homes. Many non-Tolai residents of Rabaul were repatriated to other parts of Papua New Guinea. Tolai villagers and former residents of Rabaul, be they Papua New Guineans or expatriates, mourned the passing of ‘Rabaul’. This article examines the different nostalgias for Rabaul which are articulated in the Australian print media, by Tolai villagers, and by migrants from the Sepik provinces who had lived in Rabaul prior to the eruption. The article concludes with a reflection on Rabaul as a symbol for the Papua New Guinean nation. 相似文献
