Calibrating the zenith of dinosaur diversity in the Campanian of the Western Interior Basin by CA-ID-TIMS U-Pb geochronology. [PDF]
Sci Rep, 2022 The spectacular fossil fauna and flora preserved in the Upper Cretaceous terrestrial strata of North America’s Western Interior Basin record an exceptional peak in the diversification of fossil vertebrates in the Campanian, which has been termed the ...

J Anal At Spectrom, 2021 Age determination of minerals using the U–Pb technique is widely used to quantify time in Earth's history. A number of geochronology laboratories produce the highest precision U–Pb dates employing the EARTHTIME 202Pb–205Pb–233U–235U tracer solution for ...

Detrital apatite Lu–Hf and U–Pb geochronology applied to the southwestern Siberian margin
Terra Nova, 2022 Apatite is increasingly used in sedimentary provenance studies. However, detrital apatite U–Pb geochronology can be challenging due to the presence of non‐radiogenic Pb, its intermediate closure temperature (~350–550°C) and/or age‐resetting by ...

U-Pb geochronology documents out-of-sequence emplacement of ultramafic layers in the Bushveld Igneous Complex of South Africa. [PDF]
Nat Commun, 2016 Layered intrusions represent part of the plumbing systems that deliver vast quantities of magma through the Earth’s crust during the formation of large igneous provinces, which disrupt global ecosystems and host most of the Earth’s endowment of Pt, Ni ...

GZ7 and GZ8 - Two Zircon Reference Materials for SIMS U-Pb Geochronology. [PDF]
Geostand Geoanal Res, 2018 Here, we document a detailed characterisation of two zircon gemstones, GZ7 and GZ8. Both stones had the same mass at 19.2 carats (3.84 g) each; both came from placer deposits in the Ratnapura district, Sri Lanka.
