The sample preparation facilities include a series of microscopes to allow the inspection of mineral separates, sample picking, and loading of the irradiation packets.
This laboratory develops methodology for small and difficult sample analysis often at the limits of existing mass spectrometer technology.
Ar geochronology is an experimentally robust and versatile method for constraining the age and thermal history of rocks.
The argon extraction lines are designed to incrementally heat, fuse, or ablate any potassium-bearing rock or mineral using either infrared or ultraviolet lasers.
Very small amounts of sample material, ranging in size from a single mineral grain to a few milligrams of sample are commonly analyzed with small associated analytical errors (Ar laboratory consists of single- and multiple-collector mass spectrometers each attached to custom-built, stainless steel extraction lines that operate at pressures roughly one billionth of an atmosphere.

The versatility of the Ar method permits determining the timing of processes and events such as igneous intrusions and extrusions, ore mineralization and hydrothermal fluid circulation, metamorphic cooling and exhumation, mineral formation and recrystallization, and shallow crustal faulting. Scientists are dependent on the geochronologist for data and interpretations to determine these parameters.
