The Experimental Geochemistry lab at IUPUI studies the interactions of minerals, melts, and fluids at high temperatures and pressures corresponding to a wide range of geological processes from crustal melting and vaporization caused by asteroid impacts on Earth’s surface, to the alteration of high pressure minerals by melts and fluids in Earth’s interior.

We research these processes by identifying outstanding problems from natural samples, then designing and implementing laboratory experiments to try to answer those questions.

The lab is equipped with an aerodynamic levitation laser furnace to simulate extreme temperatures relevant impact plumes (>3000 °C), and a piston cylinder apparatus to simulate pressures and temperatures in the lower crust and upper mantle (up to 25 kbar and 1600 °C).
