a Chemical zoning profile of the amphibole shown in (b). b Backscattered electron image of a calcite-hosted amphibole, with numbered circles corresponding to analysis points in (a). c–f WDS elemental maps of pyroxene and amphibole, showing raw Na (c), Fe (d), Ca (e), and Mg (f) counts. g Backscattered electron image of pyroxene and amphibole mapped in (c–f). See yellow–black square in Fig. 3c for identification of associated minerals. The yellow outline in (g) shows two chemical zones (compositions shown in f) which are indistinguishable by BSE imaging. h Chemical compositions of all pyroxenes measured in this study projected on a diopside–hedenbergite–aegirine ternary diagram. Mineral compositions available in Supplementary Data 1. Abbreviations: Aeg–aegirine, Amp–amphibole, Aug–augite, Cal–calcite, Di–diopside, Hd–hedenbergite.
