Summary of results. NTGS laser ablation ICP-MS U-Pb-Hf geochronology project: selected samples from Jervois Range 1:100 000 and TOBERMOREY 1:250 000 mapsheets, Aileron and Irindina provinces, January 2014 - December 2016

Abstract

This Record presents geochronological results from 24 samples collected from the Aileron and Irindina provinces, Northern Territory: 22 from the Palaeoproterozoic Aileron Province and two from the Neoproterozoic-Cambrian Irindina Province. The majority of the sampled units are in the Jervois range1 1:100 000 mapsheet, with one sample collected from drillhole NTGS99-1 in the TOBERMOREY 1:250 000 mapsheet. Zircons from 14 samples were analysed for U-Pb isotopes and of these, only eight yielded meaningful ages. Seventeen samples were analysed for zircon Hf isotopes of which only 13 yielded enough data for any useful conclusions to be drawn. One sample failed to yield any zircons during the mineral separation process.
