Textural and geochemical analysis of chalcopyrite, galena and sphalerite across the Mount Isa Cu to Pb-Zn transition: Implications for a zoned Cu-Pb-Zn system

The Dugald River-type, shear zone hosted, Zn-Pb-Ag mineralisation, Mount Isa Inlier, Australia

“…A syngenetic origin for some of the deposits (e.g., Mt Isa, George Fisher and Hilton) is supported by the preservation of syn-sedimentary textures. Fine-grained sphalerite and galena occur in thin laminae and bands parallel with the sedimentary layering as well as the preservation of textures suggesting intergrowth of sphalerite and galena with framboidal pyrite (e.g., Cave et al, 2020;Rieger et al, 2021). Although late metasomatic and metamorphic overprints affected these deposits, early syn-sedimentary textures are locally preserved.…”

“…World-class Zn-Pb deposits (Fig. 1c) include the Mt Isa deposit (e.g., Smith et al, 1978;Gulson et al, 1983;McGoldrick and Keays, 1990;Perkins, 1997;Davis, 2004;Cave et al, 2020), the Cannington deposit (e.g., Bodon, 1998;2002;Roache et al, 2004;Walters and Bailey, 1998), the George Fisher and Hilton deposits (Valenta, 1994a;Perkins and Bell, 1998;Chapman, 2004;Murphy, 2004;Cave et al, 2020) and the Dugald River deposit (Newbery et al, 1993;Xu, 1996;1998a;Creus, 2022). The Zn-Pb mineralisation style extends further north to the McArthur Basin to include Century, McArthur River (HYC) and Teena deposits (Broadbent et al, 1998;Feltrin et al, 2009;O'Rourke et al, 2017;Sheldon et al, 2021).…”

Variscan U-Th-Pb age for stratabound Pb-Zn mineralization in the Bossòst dome (Pyrenean Axial Zone)

“…Structures, ore textures and mineral emplacement may be difficult to interpret due to partial or total resetting and/or recrystallization of ore mineralization. In various orogenic Pb-Zn districts, the timing of mineralization and remobilization stages are debated and difficult to reconcile with geodynamic settings as, for example, in Australian sediment-hosted Pb-Zn deposits (Cave et al, 2020;Gibson et al, 2017;Gigon et al, 2020;Murphy, 2004;Perkins and Bell, 1998;Spinks et al, 2021) or in other base metal massive sulfide deposits (e.g. Admou et al, 2018;Chauvet et al, 2004;Essaifi et al, 2019;Marignac et al, 2003;Tornos et al, 2008).…”
