Zircon recrystallisation microstructures andthe implications for U-Pb dating

2021
<p>Uranium-lead dating of zircon has been used extensively in geochronological studies based on the widespread occurrence of zircon and its resistance to chemical and physical weathering. Previous research has shown that despite their apparent robustness, many zircons contain evidence for recrystallisation, such as the replacement of the ...

Air abrasion experiments in U-Pb dating of zircon

Chemical Geology, 1986
Abstract Air abrasion of zircon grains can remove metamict material that has lost radiogenic Pb and zircon overgrowths that were added during younger events and thereby improve the precision of the age measurements and permit closer estimates of the original age.

U-Pb Dating of Zircon and 40Ar/39Ar Dating of Biotite at Bingham, Utah

Economic Geology, 2001
Uranium-lead dating of zircon and 40Ar/39Ar dating of biotite provide a new estimate of the age of the Bingham hydrothermal system. The U-Pb age of zircon from the Last Chance monzonite establishes the age of crystallization of this intrusion at 38.55 ± 0.19 Ma (2 σ , MSWD = 2.08). The oldest hydrothermal event in the monzonite is dated at 38.40 ± 0.16
