The priority of our research is to understand the mechanisms at work in our environment and thus contribute to its sustainability. To do this, we use geophysical methods to investigate not only shallow layers of geology\/volcanology\/archaeology, but also deeper structures for geothermal energy exploitation. Specifically, we address the following topics:<\/p>\n

[\/et_pb_text][et_pb_toggle title=”Environmental research on soils and rocks” _builder_version=”4.24.2″ _module_preset=”default” global_colors_info=”{}”]<\/p>\n

As part of our environmental studies, we measure the magnetic properties of soils and rocks to study, e.g., pollution and\/or to more accurately determine soil characteristics. In this area, we cooperate in particular with colleagues from Poland and Belgium.<\/p>\n

[\/et_pb_toggle][et_pb_toggle title=”Geothermal research” _builder_version=”4.24.2″ _module_preset=”default” global_colors_info=”{}”]<\/p>\n

In geothermal research we measure the thermophysical properties of rocks from boreholes to determine and refine the values of the Earth’s heat flux and calculate the temperature in the Earth’s crust.
We investigate the potential for exploiting geothermal energy, and in interdisciplinary studies we look at the links between air, soil and bedrock temperature. Temperature data are also used for palaeoclimate reconstructions, including the occurrence and dynamics of permafrost.<\/p>\n

[\/et_pb_toggle][et_pb_toggle title=”Non-destructive archaeological research” _builder_version=”4.24.2″ _module_preset=”default” global_colors_info=”{}”]<\/p>\n

The aim is to streamline archaeological research by measuring magnetic susceptibility, magnetic field strength, electrical resistivity tomography (ERT) and microgravimetry. In addition to identifying hidden archaeologically significant remains, another goal is to obtain information from the magnetic and geochemical record of past human activity in the soil.<\/p>\n

[\/et_pb_toggle][et_pb_toggle title=”Research on shallow geological structures” _builder_version=”4.24.2″ _module_preset=”default” global_colors_info=”{}”]<\/p>\n

We contribute to studies of salt bodies and to search for unknown volcanic structures by gravimetry and magnetometry, supplemented by ERT measurements. This research also includes 3D gravimetric and magnetic modelling.
Since 2007, we have been cooperating with German geological organisations to search for volcanic structures in Bavaria, the Czech Republic and Saxony.<\/p>\n

We investigate the hydrogeological regime in a coal mine based on microgravimetric monitoring. In the CSA quarry, we monitor the stability of the risky slope of the Jeze\u0159\u00ed Castle mine using inclinometer stations.<\/p>\n
