The UAF Petrology Laboratory is a modern research facility for studying magmatic processes at high temperatures and pressures. The Petrology Lab also conducts research on porous materials. The lab provides high quality spectroscopic and porous media analytical services for a wide range of research and industry applications. Combined with the resources housed in the UAF AIL, the Petrology Lab and affiliated personnel can provide a comprehensive suite of analytical and research data products for a variety of geoscience research needs.
Research and analytical capabilities:
1) High pressure-temperature experimental petrology research. The UAF Petrology lab houses hydrothermal and solid media experimental apparti in support of petrology and volcanology research: a) phase equilibria studies from 1 atmosphere to ~1GPa pressure and temperatures to ~2000 C using established hydrothermal or solid media (piston-cylinder) methods and controlled or monitored oxygen fugacity; b) volatile solubility and speciation research applicable to natural volcanic and synthetic melts/glasses; c) vesiculation and crystallization kinetics studies during stepwise and continuous decompression pathways
2) Pore structure analyses on natural and experimental rock samples. Current lab resources include equipment to measure porosity, skeletal density, granular sample density, permeability, electrical resistivity, and maximum pore throat radius in porous rock samples. Although the lab applies these analyses to volcanic processes, the equipment can be applied to other areas of geoscience and enigneering including: petroleum and gas exploration, permafrost and soil studies, construction materials.
3) Micro - Fourier Transform Infrared Spectroscopy. The Petrology Lab maintains a Thermo Fisher Nicolet 6700 research grade infrared spectrometer with attached Continuum Microscope. This instrument provides transmission and reflectance infrared spectra of a wide variety of materials, including: hydrous and CO2 bearing silicate glasses, minerals, chemicals, plastics, and other materials with molecular vibrational bands in the mid-infrared. The microscope has two detectors, with its small area detector capable of resolving features as small as 10 by 10 microns. The instrument also has Attenuated Total Reflectance objectives with diamond and ZnSe crystals and a Linkham heating and cooling stage for in-situ analyses under elevated or reduced temperatures and variable gas atmospheres.
