Research funding was provided by the Australian Research Council (ARC) to W. L. (FT130100510) and J. B. (DP140102765), and CSIRO OCE fellowship to Y.M. This research is also supported by the Science and Industry Endowment Fund. The bulk XAS data and the micro-XANES images were collected at the XAS and the XFM beamlines of the Australian Synchrotron, and quick-XANES imaging was carried out at the P06 beamline of the light source PETRA III at DESY, a member of the Helmholtz Association (HGF). The DFT calculations in this work were supported by resources provided by the Pawsey Supercomputing Centre with funding from the Australian Government and the Government of Western Australia. We thank the BCC group (Stephane Cuchet, Mischa Crumbach, Ate van der Burgt) for providing the sample from Binntal. C.G.R acknowledges travel funding provided by the International Synchrotron Access Program ( ISAP) managed by the Australian Synchrotron. The authors are grateful for the helpful reviews from Professor E. Ripley, Dr S. Rowins and an anonymous GCA reviewer.
