Description
The Noble Gas Mass Spectrometry Laboratory employs the 40Ar/39Ar dating method to determining the crystallization age of geologic material and is equipped with a Mass Analyser Products MAP 215-50 rare-gas mass spectrometer. Gas extraction is achieved using either a double-vacuum Heine low-blank resistance furnace or a Merchantek carbon-dioxide continuous-fire laser. The laboratory is also equipped with a rock-preparation facility for mineral separations. In this image Master Student Jamie Russell is doing a late-night session to determine the age of one of the Samoan seamount basalts.
