Shifts in the locus of crustal thickening during Mesoproterozoic orogenesis in the Mt Isa Terrane
A fundamental change from thin-skinned to thick-skinned tectonics in the Mt Isa Terrane is interpreted to reflect a westward shift in the locus of crustal thickening during Mesoproterozoic orogenesis in northeastern Australia. Geochronological constraints indicate that west-directed, thin-skinned deformation in the eastern part of the terrane occurred before ca 1540 Ma. This upper crustal system is interpreted to link with deeper crustal thickening in the Georgetown Inlier to the east, where...[Show more]
