Dalton was supported by an Otago Museum Postgraduate Geology Scholarship and an Australasian Institute of Mining and Mineralogy Education Endowment Trust. Pyroxene trace element and isotope analyses were funded by a Foundation for Research Science and Technology Fellowship (contract UOOX1004) and University of Otago Research Grants to Scott, and a Canada Excellence Research Chairs Government of Canada program and a Canada Foundation for Innovation instrumentation grant to Pearson. We thank Y. Luo for providing assistance with orthopyroxene analyses at the University of Alberta. C. Stirling permitted analysis at the Centre for Trace Element Analysis at Otago. We thank S. Pilet and S. Kidder for comments on a draft, and K. Panter and two anonymous reviewers for thorough and constructive reviews.
