Detrital Zircon U-Pb Geochronology Applied to Tectonics

Annual Review of Earth and Planetary Sciences, 2014
Detrital zircon geochronology is rapidly developing into an essential tool in Earth science research because of the widespread occurrence of zircon in sedimentary systems; the wide range of information that can be extracted from zircon crystals; the ability to determine ages with reasonable precision, accuracy, and efficiency; and the wide range of ...

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 ...

U-Pb geochronology of grossular-andradite garnet

Chemical Geology, 2017
Abstract This study presents a new laser ablation-inductively coupled plasma mass spectrometry (LA-ICPMS) based U-Pb geochronometric method for dating grossular-andradite (grandite) garnet. Grandite is a primary skarn mineral, therefore dating its growth directly dates hydrothermal activity.

Applications of High-Precision U-Pb Geochronology

, 2023
The perpetual and persistent forward march of time is a geoscientist’s reference frame for understanding Earth’s natural changes that manifest in all scales of natural materials (e.g., minerals, fossils, glaciers, rocks, mountain belts, cratons). While indicators of relative timing can be abundant in natural materials (e.g.

How diverse is the source? Age, provenance, reworking, and overprint of Precambrian meta-sedimentary rocks of West Gondwana, Cameroon, from zircon U-Pb geochronology

Precambrian Research, 2021
The Nyong Complex and the Yaounde Group represent two crustal sequences of West Gondwana in Cameroon. We use U-Pb zircon geochronology on meta-sedimentary rocks to analyze their depositional age, provenance, and age of the high-grade metamorphic ...
