摘要

We appreciate the opportunity to discuss our paper on the Cenozoic mafic magmatism of eastern Australia and potential relationships to plate motion and are thankful to Musgrave and Schmidt (2019) for bringing the uncertainties and inconsistencies of Jones et al. (2017) to our attention. The comments from Musgrave and Schmidt (2019) focus on the paleomagnetic record of Australian plate motion, so, to begin, we note that Jones et al. (2017) did not include new paleomagnetic data. Instead, the paper presented new 40Ar/39Ar results from east Australian mafic rocks and evaluated them in light of tectonic reconstruction circuits compiled by Seton et al. (2012). To reiterate the original motivation behind our paper, we created animations from previous tectonic reconstructions to examine spatial-temporal relationships between east Australian magmatism and tectonic processes such as the opening of the Tasman and Coral Seas and collision of the Ontong Java Plateau (OJP) with the Solomon Islands. In particular, we examined (1) the age and location of mafic magmatism in eastern Australia with respect to tectonic reshuffling in the southwest pacific; (2) possible formation mechanisms of magmatic provinces in eastern Australia; and (3) the relationship between the latitude of the Australian plate according to a global moving hotspot reference frame (GMHRF; Doubrovine et al., 2012) and different apparent polar wander paths (APWPs) for Australia using previously published paleomagnetic data from Idnurm (1985), Embleton (1981), and Embleton and McElhinny (1982).
