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.

U–Pb geochronology of speleothems by MC-ICPMS

Quaternary Geochronology, 2006
Abstract Building upon the work of Richards et al. [1998. U–Pb dating of a speleothem of Quaternary age. Geochimica et Cosmochimica Acta 62, 3683–3688], we have developed a method for precise dating of speleothems beyond the range of the U–Th technique using the U–Pb decay scheme.

Partial resetting of the UPb isotope system in monazite through hydrothermal experiments: An SEM and UPb isotope study

Chemical Geology, 1997
Abstract Natural monazites of different grain sizes were treated experimentally under hydrothermal conditions and their UPb isotope systematics measured before and after the runs. Runs were carried out with monazite grain size fractions ranging from 40 to 125 μm in diameter, and on 207 Pb 206 Pb ages close to 380 Ma.

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
