• The facilities in the Department of Geology and Geophysics at the University of Minnesota to conduct geochemical research are second to none in the world. These facilities include: Rocking Autoclaves (the flexible reaction-cell system); Flow-through Hydrothermal Reactors for kinetic studies of mineral-fluid systems; Ion Chromatography (IC); Gas Chromatography (GC), Gas Chromatography-Mass Spectrometry (GC-MS); Inductively Coupled Plasma Mass Spectrometer (ICP-MS) with Laser Ablation capabilities; and, Stereo Microscopes and other mineral processing equipment.
• In addition to experimental and analytical equipment used in direct support of experimental research, computers with software (EQ3/6, GWB, TOUGHREACT) and supporting databases are available for theoretical modeling studies. Reaction path models coupled with results of experimental simulations and field (hydrothermal vent) studies provide a highly integrated approach to investigate rates and mechanisms of mass transfer in a wide range of chemical systems.
• Studies of the chemistry of hydrothermal vents benefit from the in-house development of in-situ chemical sensors and fluid samplers that takes place in the Aqueous Geochemistry Group at the University of Minnesota.
