Laboratories of Geotechnologies and Seismic Observation


The Laboratories of Geotechnologies and Seismic Observation (LGSO) represent the central laboratory institution at the GZB comprising experimental and analytical facilities for investigations at various spatial and temporal scales and a seismological observatory continuously monitoring any seismic activity in the vicinity of the GZB's own drill site.

The LGSO group covers any laboratory aspects related to applied research projects of the individual departments at the GZB. Moreover, LGSO sets up own projects with focus on three major topics:

  • 4D rock deformation
  • Physico-chemical interactions between rocks and fluids
  • Wave propagation and attenuation

As a host of first class and partly unique laboratory equipment, such as the in-situ Borehole and Geofluid Simulator (IBGS) and the multifocus CT-scanner (HECTOR) with access to the GZB's own drill site and drilling rig BO.Rex, LGSO allows for fundamental and applied research at all spatial and temporal scales – at one place – and offers its facilities as service not only to internal researchers directly involved in current GZB research projects, but also to external researchers from public, private, and commercial institutions.

You want to use our facilities for your research or work in our lab? You would like to settle your BSc or MSc project? You are looking for an internship? Feel free to contact us any time, we are looking forward to meeting you!
