Petrology of Raw Materials
How do magmatic-hydrothermal alterations at the Ramberg Pluton influence the raw material potential and suitability of the rocks for the final storage of radioactive waste?
Objective
Evaluation of the critical raw material potential due to chemical exchange caused by magmatic-hydrothermal processes in the contact zone of the Ramberg pluton and the significance of these alterations for the disposal of radioactive waste in intrusive rocks of the Harz.
Background
Magmatic-hydrothermal alteration of magmatic rocks represents an important process in the formation of ore deposits for various valuable elements (e.g., Sn, W, Mo, Li, B). These alteration processes also lead to changes in the petrophysical properties of the rocks through mineral transformations. Such alteration phenomena occur in the marginal area of the Ramberg pluton, and they are being studied mineralogically and geochemically in collaboration with the Landesamt für Geologie und Bergwesen (LAGB) Saxony-Anhalt. In addition to the enrichment of valuable elements, the structural changes in the rock are relevant for the potential disposal of radioactive waste.
