Maximum depositional age estimation revisited (2020, background): “(4) The youngest detrital zircon date estimated by Ludwig (2003)’s Monte Carlo resampling algorithm (YDZ); (5) The outcome of Ludwig and Mundil (2002)’s TuffZirc algorithm; (6) The weighted mean of the youngest three (Y3Z) or four (Y4Z) zircon dates; (7) The weighted mean of the dates in the…”
New Age Constraints for the Salamanca Formation and Lower Río Chico Group in the Western San Jorge Basin, Patagonia, Argentina: Implications for Cretaceous-Paleogene Extinction Recovery and Land Mammal Age Correlations (2014, methodology): “Final ages and uncertainties were calculated using the Isoplot Excel macro of Ludwig (2003), and quoted errors for the age calculations are presented as ± X [Y], where X refers to the analytical uncertainty only, and Y represents the analytical and systematic uncertainties combined.”
U–Th–Pb zircon geochronology by ID-TIMS, SIMS, and laser ablation ICP-MS: Recipes, interpretations, and opportunities (2015, methodology): “The community focused on high-precision dating of igneous rocks has therefore shifted away from the concordia-age concept (Ludwig, 2003) and is using instead a statistical approach on the 206 Pb/ 238 U date only.”
U‐Pb Zircon Geochronology with an Integrated LA‐ICP‐MS Microanalytical Workstation: Achievements in Precision and Accuracy (2010, methodology): “70 (Ludwig 2008), which also calculated the concordia ages, as well as the mean square of the weighted deviates (MSWD) and probability of concordance.”
Zircon M257 ‐ a Homogeneous Natural Reference Material for the Ion Microprobe U‐Pb Analysis of Zircon (2008, methodology): “Plotting and age calculations were done using the Excel-based Isoplot program (Ludwig 2003).”
IsoplotR: A free and open toolbox for geochronology (2018, methodology): “Developed by Kenneth R. Ludwig over a period of two decades, Isoplot is a user-friendly toolbox that allows geologists to calculate and visualise geochronological data within a familiar spreadsheet environment (Ludwig, 1988, 1999, 2003a, 2012).”
Community‐Derived Standards for LA‐ICP‐MS U‐(Th‐)Pb Geochronology – Uncertainty Propagation, Age Interpretation and Data Reporting (2016, methodology): “Ludwig (2003) The method used for reducing LA-ICP-MS U-(Th-)Pb data is a significant factor in the variability of results.”
