The use of the ultraviolet laser for Ar/Ar dating was pioneered at the Open University. We have gained an international reputation for high quality AR/Ar and rare gas analysis by laser ablation methods. We are dedicated to developing and modifying techniques for dating ultra-small samples to high precision, and ultra-high resolution noble gas diffusion experiments. The Ar/Ar dating method is a very versatile radiometric dating tool, generally applicable to finding the age of any potassium-bearing rock or mineral. Consequently our AR/Ar dating research activities are diverse and include: meteorite impacts, volcanoes, mountain-building, sandstone and mudrock provenance and excess argon. Our noble gas experimentation includes determining diffusion rates of different gas species in minerals and metals.
