New and existing Sm-Nd whole rock isotope data and U-Pb zircon ages from sedimentary rocks in several Australian Proterozoic Provinces hosting Zn-Pb mineralisation show a distinct transition that corresponds to a change from evolved sediment sources to more juvenile sedimentary sources at ~1650 Ma. This Sm-Nd isotopic change has been documented in the Eastern and Western Successions of the Mount Isa Inlier, the Etheridge Province of the Georgetown Inlier. A similar transition at ~1650 Ma has also been documented in the Broken Hill and Olary Domains of the Curnamona Province (Barovich and Hand 2008) and defines a continental-scale isotopic signal. The world-class, sediment-hosted Mt Isa and Hilton-George Fisher Zn-Pb Mt Isa-style deposits in the Western Mount Isa Inlier occur above the transition in sediments derived from more juvenile sources. In contrast, Pb-Zn-Ag Broken Hill-style deposits, including the Broken Hill (Curnamona), Cannington (Isa), Mount Misery (now Chloe) and Railway Flat deposits (Georgetown Inlier) (Carr et al. 2004) occur below this ~1650 Ma transition in sediments which have a much more evolved source.

This map shows public and private land tenure, including Aboriginal and Torres Strait Islander land for the whole of Australia at a scale of 1:4.7 million. The land tenure boundaries depicted on this map generally define broadly classified areas greater than 50 square kilometres. Aboriginal land areas between 0.1 and 100 square kilometres are shown more comprehensively by symbols. The information on this map is complemented by statistical tables giving the total area of the land tenure categories for each state and territory. Also available as GIS data.
