facilities






1000 ton Kawai-type Multi-anvil Apparatus
This apparatus is capable of producing pressures of ~25 GPa and temperatures up to 3000 K.  This allows us to reproduce conditions in the uppermost lower mantle. 

Rotational Drickamer Apparatus
This apparatus is capable of deforming materials to large strains, at pressures of ~22 GPa and temperatures up to 1800 K.  Using this apparatus, we have begun deformation experiments to determine the rheology of wadsleyite, the olivine polymorph in the upper half of the transition zone.  

Griggs-type Deformation Apparatus
Our two Griggs-type deformation apparatuses are capable of deforming materials at ~2 GPa and ~1600 K to shear strains up to gamma = 7 .

Field-Emission Gun SEM with EBSD
Our scanning electron microscope (SEM) allows us to conduct detailed studies of the microstructures of our samples.  Electron backscatter diffraction (EBSD) allows us to quickly and accurately determine individal grain orientations for microscopic fabric analysis. 

Micro-Raman Spectrometer
Raman spectroscopy permits rapid phase identification with minimal sample preparation. 

Infrared Spectrometer (FTIR)
Infrared spectrometry is used to determine water contents in experimental and natural samples.
