High Temperature Furnaces for Studying Magmatic Processes
The IU Paleontology Collection is formal public trust research repository for fossil material. Its 1.3 million specimens document past research projects and serve as a resource for new synthetic research on stratigraphy, paleoecology, evolution, geochemistry, and the biotic effects of climate change for researchers at Indiana University and in the international scientific community.

The department has a set of rooms dedicated to optical microscopy and photo-imaging. Research-grade polarizing microscopes allow examination of whole thin sections at the scale of 1 to 1, scaled to magnifications &rt;40X.
Shale Research Lab
The Shale Research Lab has field equipment ranging from camping gear, ladders, portable saws, rock climbing gear, a scintillometer, and a gamma ray spectrometer for the study of shale outcrops.
FEI Quanta 400 FEG (field emission environmental scanning electron microscope). Access to the nanometer realm, chemical characterization, crystal structure, grain orientation, high resolution color cathodoluminescence.
The flume facility was built to study depositional and erosional parameters of mud, and to duplicate depositional features observed in the rock record (reverse engineering mother nature). It is a work in progress because we are constantly learning and building (4 flumes at present). NSF and industry funded.
The following labs offer analytical services to both IU and non-IU students and faculty, and to commercial companies. Please contact the directors of each lab to inquire about availability and fee structure.
Analytical Geochemistry Labs
Analytical Geochemistry Laboratory (MSBII 453) is a department facility that is dedicated to the inorganic geochemistry of geologic materials (water, sediments and soils, and rock). Erika Elswick
Our CAMECA SX-50 Electron Microprobe is for research and teaching activities in geochemistry, petrology and geochronology.Chusi Li
Mineralology Facilities XRD
The mineralogy facilities at IU consist of several laboratories including an X-ray diffraction laboratory, a thermal analysis laboratory, and a clay mineral and sample preparation laboratory. David Bish
Metal Isotope Laboratory
Here in the Indiana University Department of Earth and Atmospheric Sciences we have had a long history in the application of what are often referred to as “conventional” stable isotopes (light elements such as S, C, O H and N) to studies of a range of low- to high-temperature geological processes. Technological developments over the past twenty years have now made it possible to make precise isotopic ratio measurements of many elements, even those once thought to be too “heavy” for significant isotopic fractionation or as a result of predominantly ionic bonding not likely to fractionate isotopes. Instruments like Multi-Collector Inductively Coupled Plasma Mass Spectrometers have now made it possible to determine isotope ratios for elements such as Fe, Cu, Zn, Ni, S, Mg, Ca, Mo, Cr, Sn, W, V, Ti, Se, Pt, and Hg, to name just a few. Many of the elements are redox sensitive and variations in their isotopic ratios have led to increased understanding of mechanisms that control both low- and high-temperature fractionation. We are still learning how variations in isotopic ratios function as tracers of a host of important geochemical processes. Ed Ripley
Scanning Electron Microscope
SEM-ESEM Lab. FEI Quanta 400 FEG (field emission environmental scanning electron microscope). Access to the nanometer realm, chemical characterization, crystal structure, grain orientation, high resolution color cathodoluminescence. No coating needed, can image moist materials, microbes survive study under the beam. NSF funded. Juergen Schieber
Stable Isotope Research Facility
The Stable Isotope Research Facility (SIRF) in the Department of Earth and Atmospheric Sciences houses four isotope ratio mass spectrometers dedicated to analysis of H, C, N, O, and S. Ed Ripley, Ben Underwood
