Abstract
This record presents trace-element and chronologic data collected from zircon and baddeleyite at the Australian Research
Council Centre of Excellence in Ore Deposits (CODES) at the University of Tasmania in June 2015. The work was carried out
in support of the Northern Territory Geological Survey (NTGS) regional geoscientific investigations and value adds to co-
funded drill core acquired during Geophysics and Drilling Collaborations program, Round 2. Isotope data and interpretations
for zircon and baddeleyite from samples of Mount Peake Gabbro, Arunta Region in the Northern Territory are presented
herein. The Mount Peake Gabbro is a magnetite-rich gabbro and is host to the Mount Peake Fe-V-Ti deposit. The age of the
country rocks intruded by the gabbro is unknown but is interpreted to be Palaeoproterozoic thus constraining the maximum
crystallisation age of the Mount Peake Gabbro. The samples were collected with the aim of constraining the timing of this
episode of mafic magmatism in the Arunta Region. Results from U-Pb dating yielded crystallisation ages of 1053 ± 24 Ma
for zircon and 1062 ± 21 Ma for baddeleyite, indicating that intrusion of the Mount Peake Gabbro was synchronous with
1090–1040 Ma Giles Event mafic magmatism.
