Bastnaesite: a promising U-Pb geochronological tool

Doklady Earth Sciences, 2010
One of the most complex problems in geochrono logical studies is dating endogenous ore processes. The application of the U–Pb method in solving this prob lem is constrained by the sufficiently narrow range of traditional mineral geochronometers, which, if present in ores, are strongly altered.

UPb geochronology of the Sri Lankan basement

Precambrian Research, 1994
Abstract UPb ages of zircons and monazites from ortho- and paragneisses representing the major crystalline basement units of Sri Lanka establish a new geochronological framework, which is consistent with previously published work on SmNd model ages, RbSr whole-rock ages, and UPb mineral ages.

Characterization of the potential reference material SA02 for micro-beam U–Pb geochronology and Hf–O isotopic composition analysis of zircon

, 2021
In the present work, a natural zircon megacryst SA02 (exact provenance unknown) is investigated as a new potential reference material for U–Pb geochronology and Hf–O isotopic composition analysis via micro-beam methods.

Synthesis and purification of 205Pb for UPb geochronology

Chemical Geology: Isotope Geoscience section, 1987
Abstract 205Pb is a synthetic isotope of great utility in UPb geochronology, but it has never been widely available in a purified, useable form. We have successfully completed two production runs with a total yield of ∼100μg 205Pb. The isotope was produced by 24–27-MeV proton irradiation using cyclotron facilities of Atomic Energy of Canada Limited

U–Pb geochronology: its development and importance in Canada

Canadian Journal of Earth Sciences, 2023
This article presents a history of the development of U–Pb geochronology with emphasis on the role of Canadian researchers and some of its applications to Canadian geology. Modern U–Pb dating is the result of work by many individuals over the past 60 years, but the most important was Tom Krogh, who established methods that allowed determination of ...

Timing of the Arabia-Eurasia continental collision—Evidence from detrital zircon U-Pb geochronology of the Red Bed Series strata of the northwest Zagros hinterland, Kurdistan region of Iraq

Geology, 2018
One of the major debated aspects of the Zagros orogenic system in the Middle East is the timing of onset of continental collision between Arabia and Eurasia.
