U-Pb zircon ages from leucogneiss in the Etheridge Group and their significance for the early history of the Georgetown region, north Queensland

Black, Lance; Withnall, I W; Gregory, P; Oversby, B; Bain, J. H. C.

Description

The Einasleigh Metamorphics form part of the Etheridge Group and are interpreted as the lowest exposed part of the Georgetown Inter of north Queensland. Due to a dearth of interbedded felsic igneous rocks that would be suitable for isotopic dating, the depositional age of the Etheridge Group has long been uncertain. This study presents U-Pb SHRIMP dating of zircons from leucogneiss in the Einasleigh Metamorphics. Based on field and geochemical evidence, and the nature of the contained zircons,...[Show more]
