Resolving Bias in Laser Ablation Geochronology

Workshop on Data Handling in LA-ICPMS U-Th-Pb Geochronology; Charleston, South Carolina, 6–8 March 2013



Increasingly, scientific investigations requiring geochronology utilize laser ablation (LA)–inductively coupled plasma mass spectrometry (ICPMS), taking advantage of the efficiency and throughput possible for uranium-thorium-lead (U-Th-Pb) dating. A number of biases exist when comparing data among laboratories and an ongoing community-based effort is working to resolve and eliminate these biases to improve the accuracy of scientific interpretation based on these data.
