Mesoproterozoic Tasmania: Witness to the East Antarctica-Laurentia connection within Nuna: REPLY

“…Our detrital zircon U-Pb-Hf isotopic data and paleocurrent indicators from the lower-middle Rocky Cape Group (RCG) of northwest Tasmania, a >10-km-thick package of marine sedimentary rocks, are consistent with a provenance including basement terranes in the southern Mawson continent (East Antarctica) and southwest Laurentia, supporting a SWEAT-like configuration for the supercontinent Nuna between 1.45 and 1.3 Ga (Mulder et al, 2015). Moore and Betts (2016) challenge our proposed paleogeographic position for Tasmania within Nuna. Instead, they champion an alternative position for Proterozoic Tasmania that they claim better fits elements of Tasmanian geology outside of the RCG (Moore et al, 2015).…”
