The Osmium Isotope Signature of Phanerozoic Large Igneous Provinces
Geophysical Monograph Series, Page 229-246., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Regional zircon U-Pb geochronology for the Maniitsoq region, southwest Greenland. [PDF]
Sci Data, 2021 AbstractZircon U-Pb geochronology places high-temperature geological events into temporal context. Here, we present a comprehensive zircon U-Pb geochronology dataset for the Meso- to Neoarchean Maniitsoq region in southwest Greenland, which includes the Akia Terrane, Tuno Terrane, and the intervening Alanngua Complex.

An algorithm for U–Pb geochronology by secondary ion mass spectrometry [PDF]
Geochronology, 2022 Abstract. Secondary ion mass spectrometry (SIMS) is a widely used technique for in situ U–Pb geochronology of accessory minerals. Existing algorithms for SIMS data reduction and error propagation make a number of simplifying assumptions that degrade the precision and accuracy of the resulting U–Pb dates. This paper uses an entirely new approach to SIMS

Modeling apparent Pb loss in zircon U–Pb geochronology
Geochronology, 2023 Abstract. The loss of radiogenic Pb from zircon is known to be a major factor that can cause inaccuracy in the U–Pb geochronological system; hence, there is a need to better characterize the distribution of Pb loss in natural samples. Treatment of zircon by chemical abrasion (CA) has become standard practice in isotope dilution–thermal ionization mass ...

A Sample Characterization Toolkit for Carbonate U-Pb Geochronology [PDF]
, 2020 Abstract. Laser ablation U-Pb analyses of carbonate (LAcarb) samples has greatly expanded the potential for U-Pb dating to a variety of carbonate producing settings. Carbonates that were previously considered impossible to date using isotope dilution methods may preserve domains that are favorably interrogated when using spatially resolved laser ...

Algorithms and software for U‐Pb geochronology by LA‐ICPMS [PDF]
Geochemistry, Geophysics, Geosystems, 2016 AbstractThe past 15 years have produced numerous innovations in geochronology, including experimental methods, instrumentation, and software that are revolutionizing the acquisition and application of geochronological data. For example, exciting advances are being driven by Laser‐Ablation ICP Mass Spectrometry (LA‐ICPMS), which allows for rapid ...

A calcite reference material for LA‐ICP‐MS U‐Pb geochronology [PDF]
Geochemistry, Geophysics, Geosystems, 2017 AbstractU‐Pb dating of calcite is an emerging but rapidly growing field of application in geochronology with great potential to inform problems in landscape, basin, and mountain belt evolution, through age determination of diagenetic cements, vein mineralization, and geological formations difficult to date otherwise.
