Detailed structural mapping from the northern Mount Painter Province indicates that the metasediments of the Radium Creek Group underwent both Mesoproterozoic and Palaeozoic poly-deformation (Figure 1). Early north directed D1-D2 deformation is accompanied by upper amphibolite facies metamorphism. This deformation is characterised by recumbent folds that are preserved in the hinges of NE-SW trending doubly-plunging upright F3 folds (Armit et al., 2012). U-Pb-Hf dating of zircons from the Radium Creek Group identifies a consistent maximum depositional age for the Radium Creek Metamorphics of ca. 1596-1592 Ma across the Paralana Fault with a εHf range between -5.5 and +4. The timing of D1-D2 is constrained between this ca. 1592 Ma maximum depositional age and the minimum depositional age indicated by the truncation of the S1-S2 fabrics during the shallow-level emplacement of the ca. 1585-1569 Ma (Elburg et al., 2001; Fraser and Neumann, 2010; Neumann, 2001; Neumann et al., 2009) porphyritic Mount Neill Granite. This indicates that the Radium Creek Group were deposited, buried to mid-crustal levels and exhumed within 7 Myrs between 1592 and 1585 Ma before switching once again during the onset of NW-SE directed shortening during D3 (Armit et al., 2012). This time-frame is similar to that of modern orogens such as the Late Miocene-Present Kaikoura Orogeny of southern New Zealand (Landis and Coombs, 1964; Kamp, 1984). An S3 fabric overprints the earlier S1-S2 fabrics in the metasediments and extends into the Mount Neill Granite as a steeply dipping NE-SW trending gneissosity. The D3 event is constrained by the presence of this S3 foliation in the ca. 1585-1569 Ma Mount Neill Granite, the ca. 1552 Ma emplacement age (Fraser and Neumann, 2010) of the undeformed Hodgkinson Granodiorite and dating of ca. 1555 Ma metamorphic overgrowths on zircons from the Radium Creek Group (Armit et al., 2012). Repeated reactivation of the Proterozoic basement architecture constitutes significant deformational phases in the Mount Painter Province. During the development of the Neoproterozoic Adelaidean basins a series of shallow north-plunging quartz defined stretch lineations along the NE-SW trending Paralana Fault Zone record a phase of transtensional movement. NW-SE directed D5 deformation produced reverse movement along the Paralana Fault and tightened the pre-existing upright F3 folds producing a shallow NE-SW trending crenulation lineation on the steeply dipping bedding surfaces of the Radium Creek Group. NE-SW directed D6 shortening warped the existing structures producing type 2 interference patterns with the rotation of F3 and F5 folds axes. These Palaeozoic D5-D6 deformational events most likely reflect the ca. 500 Ma (Dutch et al., 2005; Foden et al., 2006; Harrison and McDougall, 1981; Sandiford et al., 1998) Delamerian Orogeny but might relate to deformation during the Ordovician Alice Springs Orogeny (McLaren et al., 2002). Further brittle deformation that overprints the D6 structures along the Paralana Fault such as a hematite bearing fault breccia at the Mount Neill Granite and metasediment interface highlight the protracted geodynamic evolution of the Paralana Fault Zone. The Mesoproterozoic geodynamic evolution component of the Mount Painter Province differs to that of the southern Gawler Craton and Curnamona Province, but correlates better with the Mount Isa Inlier and the northern Gawler Craton (Figure 2). This provides important Early Mesoproterozoic constraints for future tectonic models of eastern Proterozoic Australia.
