Gneissic metasediments and a granitic gneiss from an EW-striking structural belt in the southern Aileron Province yield ages reflective of the Inkamulla Igneous Event (1754-1741 Ma) and the Chewings Event (1593-1545 Ma), along with magmatic ages of 1627 and 1641 Ma. The Chewings age is interpreted to represent structural reworking associated with discrete shear zones along the northern margin of the EW belt. Magmatic ages of ca. 1640 Ma typically associated with Warumpi Province magmatism and deformation are found within the study area, which weakens the argument that the Warumpi terrane is exotic from the Aileron Province. The metamorphic conditions of 780-920°C and 5-10 kbars indicate an elevated geothermal gradient.enHonours; Geology; Arunta; Aileron Province; U-Pb geochronology; monazite; reworking; migmatite; Proterozoic Australia; Inkamulla; ChewingsThesis
