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.

hydrocarbon resources are created, when they formed, and where they are located.
 

Metals--

Our work has led directly to discovery of ore for the mineral industry. The AIRIE Program established the protocol for successful Re-Os dating of molybdenite, from mineral separation to treatment of analytical data. We developed a double Os spike to address young (or low Re) molybdenites, and spearheaded the development of a molybdenite reference material (RM 8599, Henderson) to share with the geoscience community. RM 8599 is distributed by NIST, and available for global interlaboratory comparison of the Re-Os age. 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 found only very low levels of Re and Os in native gold.
