Argon Geochronology and the National Argon Map (NAM)

40Ar/39Ar geochronology is a key geochronometer for many Earth Science disciplines for example timing eruptions, magmatism, fluid alteration, extinctions, impacts, orebodies and orogenies.

For tectonicists and structural geologists 40Ar/39Ar geochronology is the only method that allows the direct dating of a rock fabric by examining common rock forming minerals such as white mica or K-feldspar. 40Ar/39Ar geochronology is unique in that, it allows geospeedometry - the science that concerns rate and duration of geological processes.

The RSES argon facility undertakes Ar/Ar analysis for research purposes, for students and for commerical research. Contact us for details.
