The earliest Cambrian record of animals and ocean geochemical change
The Cambrian diversification of animals was long thought to have begun with an explosive
phase at the start of the Tommotian Age. Recent stratigraphic discoveries, however, suggest …

U-Pb constraints on pulsed eruption of the Deccan Traps across the end-Cretaceous mass extinction
Temporal correlation between some continental flood basalt eruptions and mass extinctions
has been proposed to indicate causality, with eruptive volatile release driving environmental …

Community‐derived standards for LA‐ICP‐MS U‐(Th‐) Pb geochronology–Uncertainty propagation, age interpretation and data reporting
The LA‐ICP‐MS U‐(Th‐) Pb geochronology international community has defined new
standards for the determination of U‐(Th‐) Pb ages. A new workflow defines the appropriate …

238U/235U Systematics in Terrestrial Uranium-Bearing Minerals
The present-day 238U/235U ratio has fundamental implications for uranium-lead
geochronology and cosmochronology. A value of 137.88 has previously been considered …

Zircon U-Pb geochronology links the end-Triassic extinction with the Central Atlantic Magmatic Province
The end-Triassic extinction is characterized by major losses in both terrestrial and marine
diversity, setting the stage for dinosaurs to dominate Earth for the next 136 million years …

Calibrating the end-Permian mass extinction
The end-Permian mass extinction was the most severe biodiversity crisis in Earth history. To
better constrain the timing, and ultimately the causes of this event, we collected a suite of …

(U-Th)/He chronology: Part 1. Data, uncertainty, and reporting
The field of (U-Th)/He geochronology and thermochronology has grown enormously over
the past∼ 25 years. The tool is applicable across much of geologic time, new (U-Th)/He …

High-precision U-Pb zircon dating identifies a major magmatic event on the Moon at 4.338 Ga
The Moon has had a complex history, with evidence of its primary crust formation obscured
by later impacts. Existing U-Pb dates of> 500 zircons from several locations on the lunar …

Rapid eruption of the Columbia River flood basalt and correlation with the mid-Miocene climate optimum
Flood basalts, the largest volcanic events in Earth history, are thought to drive global
environmental change because they can emit large volumes of CO2 and SO2 over short …
