The Arizona LaserChron Center is an NSF multi-user facility that is designed to address problems in Earth Science through the generation of U-Th-Pb geochronologic data and complementary geochemical information by Laser Ablation ICP Mass Spectrometry. Our primary goals are as follows:
- Generate U-Th-Pb ages, Hf isotope ratios, and trace element concentrations of the best possible precision, accuracy, and spatial resolution.
- Provide opportunities for researchers from around the world (and especially NSF-supported scientists) to use our instruments and expertise to address geologic problems.
- Push the development of new applications of laser ablation ICP mass spectrometry.
- Enable researchers and students to learn the theory and analytical techniques of U-Th-Pb geochronology and Hf isotope geochemistry.
The main instruments utilized at the Arizona
LaserChron Center include a Nu Plasma multicollector ICPMS, a Thermo Element2 single-collector ICPMS, two Photon Machines Analyte G2 excimer lasers, and a Hitachi 3400N SEM, all of which are dedicated to ALC research. These instruments were acquired with support from the University of Arizona, the National Science Foundation, and ExxonMobil Upstream Research.
