TANG3O: Thermochronology and Noble Gas Geochronology and Geochemistry Organisation Earth Sciences, University of Tasmania, November 6-7th, 2019

Tuesday 5th November 2-5pm: LADR Laser Ablation Short Course Venue: CODES Conference Room, Earth Science, Clark Rd, Sandy Bay Leonid Danyushevsky will present a short course describing the use of LADR laser ablation in geochronology. The workshop will;

- Present the capabilities and workflow in LADR for processing U-Pb LA-ICPMS analyses, including loading data, setting up quantification protocols and options, common Pb correction on calibration reference materials, error propagation, and data export.

- Outline further developments planned for release next year. - There will be an opportunity for participants to provide feedback on current capabilities and future

developments.
