... of the Dyamberin and Nambucca blocks show distinct sedimentological features indicative of deposition in deeper water environments relative to the other lower Permian rocks farther west. Within the Nambucca block, samples from the Kempsey beds and Nambucca slate show remarkably similar geochronological provenances...

... investigation is required in order to determine a robust maximum depositional age and to establish the tectonic setting during sedimentation. In order to better understand the timing of deposition and provenance of the Nambucca block, zircon crystals were extracted and dated. Slate and sandstone...

... and Kromberg ( 1997 ) for a detailed CMC and OMM study (one sample every 500 m). Selected samples of those analysed by Printz and Kromberg ( 1997 ) were used for the K–Ar dating. The sample locations are reported in Fig.  2 . Shales, slates, and phyllites were selected to cover different thermal grades...

The presence of blueschist metamorphics with 39–44 Ma K–Ar “peak” glaucophane ages and 23–27 Ma K–Ar phengite “uplift” ages ( Pigram and Davies 1987 ) ( Fig. 2C ) suggests...

... (e.g. Korsch & Harrington 1987 ) have argued that oroclinal bending occurred during the Early to Middle Permian (280-265 Ma). They relate this to the intense deformation of the Nambucca block ( Leitch 1978 ; Coney et al. 1990 ), and infer a north-to-south 450-500 km relative movement above...
