Although the exploitation of strategic important mineral deposits is currently feasible down to a depth of ~ 1000 m, the extension of ore deposits in Germany is poorly known. The BMBF funded DESMEX (Deep Electromagnetic Sounding for Mineral Exploration) project focuses on the development of an electromagnetic exploration system which can be used for the exploration of mineral resources for depths down to 1000 m. The main focus lies in the exploration of potential mineral deposits in Germany.
Ore mineralization leads to an increase of electrical conductivity in the host rock. Therefore, innovative methods are developed, which are able to image zones of high conductivity with respect to the intended exploration depth and deliver insights in the geometry of the ore deposit. In order to obtain an high coverage as well as an high resolution, air borne and ground based methods are combined in a semi airborne controlled source EM (CSEM) concept. This concept was tested in an old antimony mining area in eastern Thuringia.
In the framework of DESMEX, the University of Cologne carried out ground based (long offset) transient-electromagnetic (LOTEM) measurements. Within the LOTEM validation study, an independent resistivity model of the survey area was derived, which serves as reference model for the semi airborne concept and is integrated in a final mineral deposition model.
This data publication (https://doi.org/10.5880/GIPP-MT.201716.1) 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).
