The impact of mining activities on the environment reflected by pollen, charcoal and geochemical analyses

Abstract

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.
