EP4 - Mineralized Fluids


Goals


Mineralized fluids play an important role in geological history of the Thuringian Basin. Mineralizations of fissures and ruptures show what fluids are made of that intruded and circulated in the Basin. They tell us about their physico-chemical characteristics and their development during ever changing boundaries. A spatial-temporal mapping and comparison to recent anomalies show that the circulation system was influenced by intruding hot fluids. Their chemical characteristics allow conclusions for where are the fluids come from and what they consist of. The first goal of sub-project 4 is to take stock and analyze the existing range of mineralization of fissures. These data will cornerstone the reconstruction of the Thuringian Basin model.

Potentially, mineralization of fissures are sources for metals and semi-metals in ground water, and therefore in drinking water, too. Alteration processes change primary minerals over time and discharge dangerous toxic solids, for instance arsen. Knowledge of the primary mineralizations is a first step towards a description of alteration processes. A second goal of EP4 is to describe the natural arsen concentration in the Basin quantitatively and qualitatively. Arsen adsorbing geogene minerals are identified and analyzed. Then all thermo-dynamic and kinetic characteristics of these minerals are determined in order to get a physico-chemical model. The purpose of this model is to reliable forecast the development of arsen contamination not only in the Thuringian Basin but world wide in similar geological formations. A model like this can check for efficiency of new water decontaminating technologies before implementing. Therefore quantitative knowledge of arsen minerals may help to secure sustainability of water resources.
