The Geologic Time Scale 2012
TL;DR: The Geologic Time Scale (GTS) as mentioned in this paper is an international geologic time scale for deciphering the history of our planet Earth and has been widely used in the literature.

TL;DR: Four high-precision U-Pb ages for Neoproterozoic rocks in northwestern Canada are presented that constrain large perturbations in the carbon cycle, a major diversification and depletion in the microfossil record, and the onset of the Sturtian glaciation.
Journal ArticleDOI
Derivation of isotope ratios, errors, and error correlations for U‐Pb geochronology using 205Pb‐235U‐(233U)‐spiked isotope dilution thermal ionization mass spectrometric data
TL;DR: In this article, a comprehensive treatment of the derivation of U-Pb isotope ratios and their corresponding uncertainties from isotope dilution thermal ionization mass spectrometric measurements is presented.
Journal ArticleDOI
Reassessing the uranium decay constants for geochronology using ID-TIMS U–Pb data
TL;DR: In this paper, the U-Pb systematics of zircon and xenotime on the single-to sub-grain scale by high-precision ID-TIMS geochronology on 11 rock samples ranging from 0.1 to 3.3 Ga.
Journal ArticleDOI
U-Pb zircon and titanite systematics of the Fish Canyon Tuff: an assessment of high-precision U-Pb geochronology and its application to young volcanic rocks
TL;DR: A large data set of single and multi-grain zircon and titanite analyses from a sample of the Oligocene Fish Canyon Tuff (FCT), a voluminous ash flow from the San Juan Mountains of Colorado and widely used 40Ar/39Ar geochronological standard, has been used to evaluate the influence of various sources of analytical and geological uncertainty on the calculated age of this tuff by the isotope dilution U-PbZircon method as discussed by the authors.
