Magnetotelluric and Radiomagnetotelluric measurements near Geyer in the Ore Mountains, Germany

The region of Geyer in the Ore Mountains (Erzgebirge) of Germany, situated approximately 110 kilometres south of Leipzig, has a long history of ore mining. The region is known for its deposits of tin, zinc, tungsten, molybdenum, copper, iron, silver, and indium. Due to this long history and known reservoir potential, this area was selected as a test site for the Innovative, Non-invasive and Fully Acceptable Exploration Technologies (INFACT) project. INFACT is a EU funded project aiming to foster new and innovative non-invasive methods for the exploration of new mineral deposits and is coordinated by the Helmholtz Institute Freiberg for Resource Technology (HIF) at Helmholtz-Zentrum Dresden-Rossendorf (HZDR). Within the framework of this project, the GFZ - German Research Centre for Geosciences, Potsdam, Germany, acquired magnetotelluric (MT) and radiomagnetotelluric (RMT) data near Geyer. The main objectives of these measurements were to map the shallow subsurface for mineral deposits and to evaluate the potential of these methods in densely populated areas with high levels of anthropogenic noise. This data publication (10.5880/GIPP-MT.201933.1) encompasses a detailed report in pdf format with a description of the project, information on the experimental setup, data collection, instrumentation used, recording configuration and data quality. The folder structure and content of the data repository are described in detail in Ritter et al. (2019). Time-series data are provided in EMERALD format (Ritter et al., 2015).
