Palaeoproterozoic sedimentary rocks of the McArthur-Mt Isa-Cloncurry mineral belt of northern Australia host the world's most important zinc repository, several world-class Cu-Au deposits and Australia's principal uranium reserves. Advances in exploration techniques in the 1980s led to the discovery of several major deposits, including Walford Creek and Grevillea.

This thematic issue comprises 12 papers organised under the three main objectives or themes of the NABRE project. The first two manuscripts consider the evolution of metamorphic and stratigraphic basement to the prospective intervals of the Mt Isa, McNamara, Fickling and McArthur Groups. The next two papers document SHRIMP zircon and palaeomagnetic datasets used to constrain the sequence stratigraphic results. The remaining set of eight papers report the results of the integrated chronostratigraphic analyses. The sequence-stratigraphic papers are arranged in approximate chronological order and progress from southeast to northwest across the outcrop belt. The framework studies documented herein will be of use to geoscientists worldwide. The processes of basin evolution will assist geoscientists to unravel the early phases of basin evolution in Palaeoproterozoic successions now preserved as structurally dismembered and metamorphosed provinces in Australia and overseas.
