"In situ micro-analytical characterisation of zircon U-Pb and Hf isotop" by Ryan North
Abstract Uranium-Pb and Hf isotopic analysis of zircon crystals provides a crystallisation age and origin of the mineral, critical information to investigate Earth’s history. Zircon geochemistry can vary over micrometre scales; therefore, natural reference materials that are used for zircon analyses need to be well characterised before valid measurements can be acquired for ‘unknowns’. This study aimed to assess U-Th-Pb isotope, Hf isotope and trace element heterogeneity of four widely used zircon reference materials: ‘91500’, ‘Mud Tank’, ‘Temora’ and ‘Plešovice’, as wel...
