Basin inversion and supercontinent assembly as drivers of sediment-hosted Pb-Zn mineralization in the Mount Isa region, northern Australia

Gibson, George; Hutton, L J; Holzschuh, J.

Description

Deep seismic reflection imaging combined with geochronological, palaeomagnetic and stratigraphic data indicate that the world class sediment-hosted Pb-Zn deposits of northern Australia are preferentially concentrated in the post-extensional syn-inversion fraction of the Calvert and Isa superbasins. These fractions were deposited at 1650 - 1640 Ma and 1615 - 1575 Ma respectively, and overlap the age of known orogenic events in both Australia and western Laurentia, pointing to a common origin...[Show more]
