Evaluation of temperature-time conditions for the chemical abrasion treatment of single zircons for U–Pb geochronology

Huyskens, Magdalena H.; Zink, Sonja; Amelin, Yuri

Description

Partial loss of radiogenic Pb and presence of older grains or cores (inheritance) are the main obstacles for accurate and precise U–Pb geochronology of magmatic zircons by ID-TIMS (isotope dilution thermal ionisation mass spectrometry). Sequential annealing and leaching (chemical abrasion, (Mattinson 2005)), restores crystallinity to zircons with low to medium radiation damage, and removes parts of the zircon with strongly radiation damaged crystal lattice, effectively eliminating Pb loss.
