Abstract
The Proterozoic Mount Isa Inlier records an extensive history of sedimentation, magmatism, tectonism, and mineralisation. SHRIMP geochronology has been integrated with sequence stratigraphy and facies analysis to develop a regional chronostratigraphic framework for sedimentary packages of the Leichhardt and Calvert Superbasins in the Western Fold Belt. Determining the depositional age and regional extent of these packages is important because they are possible source regions for younger Pb mineralising systems, and because the geometries of these basins have an important control on the migration of fluids and on the development of the overlying ca. 1670 to 1575 Ma Isa Superbasin. New SHRIMP geochronology integrated with basin analysis recognises three supersequences in the Leichhardt Superbasin .....
