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.

NanoSIMS imaging method of zircon U-Pb dating

Science China Earth Sciences, 2016
We report an imaging method of zircon U-Pb dating with NanoSIMS 50L, which overcomes the significant U-Pb fractionation as the pit was sputtered deeper during conventional spot mode analysis and can be applied to irregular small grains or heterogeneous areas of zircon.

U‐Pb zircon dating of Stockholm granite at Frescati

GFF, 1995
Abstract U‐Pb zircon dating of a sample of grey Stockhohn granite from Frescati just north of Stockholm yielded an upper intercept age of 1803+23 ‐19 Ma, similar to earlier age determinations, and interpreted as the age of crystallization of the granite.
