The ANGL-ARHDL sister facilities (Arizona Noble Gas Laboratory and Arizona Radiogenic Helium Dating Laboratory) at the University of Arizona were founded in 2019 and 2006, respectively, for research in Earth, planetary, and environmental sciences, using geochronologic and geochemical approaches applied to a wide variety of sample types including fluids, minerals, and rocks. We use noble-gas-based analysis for geochronology, tracing, and many other purposes, with a range of multicollector noble gas mass spectrometers (Helix MC10+ and Argus VI) with automated, accessible extraction and purification lines, an Element2 HR-ICP-MS, quadrupole mass spectrometers with laser extraction, and several high-T furnaces.
Our goal is to provide analytical services as well as research experience and training for collaborators and students in a wide range of academic, industry, and other organizations, through visits, analyses, interpretations, and workshops for diverse student groups.
Our research and collaborations include applications of noble gases to tectonic, magmatic, deformational, and sedimentary systems using the (U-Th)/He and 40Ar/39Ar and K/Ar systems, and we are currently developing our techniques for cosmogenic and nucleogenic 21Ne, 4He/3He thermochronology, and measurement of all noble gas isotopes in fluids.
