Snæfell zircon geochronology and geochemistry

Abstract:
Zircon-based U-Pb geochronology, trace element concentrations, and O and Hf isotope compositions for Snæfell, an off-rift volcano in eastern Iceland. U-Pb zircon ages range from 545±59 to 266±16 ka (2SE), zircon δ18O is restricted to ~3.5 to 4‰, and zircon εHf ranges ~+13 to ~+17. Ti concentrations in zircon <5 ppm suggest a cool, near-solidus, crystallization environment for the majority of the zircon’s pre-eruptive history, with elevated Ti in zircon surfaces suggesting a late thermal perturbation.
