Abstract:

The Neues Potential project presents an integrated metallogenetic model for the Eastern Erzgebirge, focusing on magmatic-hydrothermal processes responsible for Sn-Li-(W) and Ag-Pb-Zn mineralizations. By combining published data with new geochronological and advanced structural interpretations, this study refines the timing and tectonic controls of ore formation. As a result, the Altenberg-Teplice Caldera is identified as a key region for Sn-Li-(W) mineral systems, while tectonic complexity controls the epithermal Ag-Pb-Zn deposits in the Freiberg District. In this presentation, we show how innovative age-dating reveals multi-phase mineralization events spanning millions of years align with regional tectonic activity, offering valuable ore deposit exploration strategies. The findings of the Neues Potential project offer valuable insights into sustainable targeted mineral exploration, enhancing resource security within the EU.

The Geokolloquium informs its guests and the staff of the State Office for the Environment, Agriculture and Geology through lectures on geoscientific work and results. It is a scientific discussion platform where experiences can be exchanged and suggestions can be given.
