Palaeomagnetism of the Southeastern McArthur Basin: poles, overprints and reversals

Abstract

The remanences of approximately 1800 samples from the southeastern McArthur Basin in northern Australia were analysed to define in detail the Australian apparent polar wander path for a period centred at ~1670 Ma and to develop a Proterozoic reversal stratigraphy for correlation and dating. The samples were collected from volcanic, clastic and carbonate sequences of mainly the Batten Fault Zone southwest of the HYC deposit, and were supplemented by sampling at the eastermost part of the Basin (Fig. 1).
