Behaviors of rock, porous and fractured media, and other materials of interest in Earth and Environmental Sciences are examined and tested in the “ROCK LAB”. The “ROCK LAB” houses the Geothermal Lab, where flow, geophysics, mechanics, and chemistry of stressed samples at elevated temperatures are quantified; the Rock Imaging Lab, where a medical X-ray CT scanner is used to observe phenomena from ambient conditions through high pressure and high and low temperatures; and the Rock Lab itself, where the mechanical and geophysical behavior of samples under stress is quantified. The lab also houses a microscope lab, a gas chromatograph, a number of load frames, numerous pressure vessels, high pressure pumps, ovens, a Design Bench, and general lab space.
