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).
News from the lab
Ian Marrs was awarded the 2020-2021 Mirsky Fellowship from the Earth Sciences Department at IUPUI and the 2020-2021 Andromeda Movement Scholarship! Congratulations, Ian!!
Lindsey Powell won best poster at the 2019 IUPUI Student Research and Engagement Day! Lindsey’s UROP research project is on impact ejecta spherules from the the newly described Tanis site where the moments after the Chicxulub impact are extremely well preserved.
AGU 2018 – Peng Ni is presenting collaborative work between IUPUI and the Carnegie Institute on Cu isotope fractionation during tektite formation. Watch this video describing the research he will present at the Fall AGU meeting.
Cam gave Saturday Morning Science talk at the University of Missouri about some research from the group. Click here to watch, but fast-forward to 17:07!
Seconds after impact: Insights into the thermal history of impact ejecta from diffusion between lechatelierite and host glass in tektites and experiments was recently published in Geochimica et Cosmochimica Acta.
