Intercalibration and age of the Alder Creek sanidine 40Ar/39Ar standard
Abstract The accuracy of 40 Ar/39 Ar geochronology relies in large part on precise and
accurate calibration of the ages and K-Ar isotopic compositions of standards. A widely used …

Re-evaluation of the ages of 40Ar/39Ar sanidine standards and supereruptions in the western US using a Noblesse multi-collector mass spectrometer
The rewards from resolving the tempo of magmatic, paleobiologic, paleoclimatic, and
tectonic processes at better than the per mil level of precision have spurred a quest within …

A new stratigraphic framework built on U-Pb single-zircon TIMS ages and implications for the timing of the penultimate icehouse (Paraná Basin, Brazil)
The timing of the late Paleozoic glaciation and its terminal deglaciation in the Paraná Basin,
Brazil, is unconstrained and prohibits correlation of the Paraná Basin ice record with other …

Protracted near-solidus storage and pre-eruptive rejuvenation of large magma reservoirs
Building super-eruptive magma reservoirs in the cold, upper parts of Earth's crust requires a
significant influx of magma over an extended period, sufficient to allow the magma to …

Secondary ionization mass spectrometry analysis in petrochronology
AK Schmitt, JA Vazquez - Reviews in Mineralogy and …, 2017 - pubs.geoscienceworld.org
The goal of petrochronology is to extract information about the rates and conditions at which
rocks and magmas are transported through the Earth's crust. Garnering this information from …
