AIRIE Mission Statement

To set an example for ethical practices,
To pursue excellence in science and technology,
To seek global applications for fundamental discoveries,
To advance the geosciences for the benefit of Earth and her inhabitants.

We will accomplish these goals by diligence and creativity, by engaging
other disciplines, embracing new ideas, and respecting diverse perspectives.
Re-Os Geochronology and Os Isotope Tracer Studies
Applied to Sulfides, Black Shales, and Hydrocarbons

Re-Os geochemistry enlightens our understanding of how METAL and
hydrocarbon resources are created and where they are located.


Our work has led directly to discovery of ore for the mineral industry. AIRIE established the protocol for successful Re-Os dating of molybdenite, from mineral separation to treatment of isotopic data. We developed a double Os spike to address young (or low Re) molybdenites, and forwarded a new molybdenite reference material that is distributed by NIST for global interlaboratory comparison. We also work with other sulfide and oxide minerals such as pyrite, arsenopyrite, chalcopyrite, and magnetite to provide age and source information through Re-Os isochrons. We have examined Re-Os in gold.
