Abstract

The Duchess-Urandangi region covers the southern part of the Precambrian Mt Isa Inlier and small parts of the early Palaeozoic Georgina and Mesozoic Eromanga Basins. The Precambrian is represented by sedimentary rocks and volcanics which have been tightly folded, extensively faulted, intruded by numerous granite plutons and mafic bodies, and regionally metamorphosed to the greenschist and amphibolite facies. The geological evidence suggests that the Mt Isa Inlier evolved during the Proterozoic in an intracratonic tectonic setting, rather than at a continental margin. Since about 1500 m.y. ago the inlier has been an essentially stable tectonic unit.
