The Geosystems Engineering Laboratory facilitates the preparation, characterization, testing and visualization of geosystems from nanometer to meter scales. It is equipped with XRD, XRF, BET and TGA for nanoscale characterization of the mineralogy and pore space. It uses two fully automated triaxial systems to simulate the shallow and deep geosystems in their in-situ temperature-, stress- and flow conditions. In addition, the photoelastic tests provide novel and unique probes into the intrinsic physics of geosystems with strong fluid-solid coupling.
