Figure F1 (continued). H. Sample PM11 (193-1188A-12R-2, 47 cm): gray-green flow-banded coherent dacite. Powder of separates: P011 (light gray: XRF, ICP-MS, F, Cl,

¹⁸O_silicate, ⁸⁶Sr/⁸⁷Sr_silicate) and P069 (dark gray: XRF, ICP-MS, F, Cl). I. Sample PM14 (193-1188A-14R-1, 86 cm): white, pseudoclastic, intensely veined coherent dacite. Powders: P012 (bulk rock: XRF, ICP-MS,

¹⁸O_{anhydrite + silicate}, ⁸⁶Sr/⁸⁷Sr_{anhydrite + silicate}) and P070 (separate of white kernels: XRF, ICP-MS). J. Sample PM15 (193-1188A-14R-1, 107 cm): volcanic breccia. Powders of separates: P014 (matrix: XRF, ICP-MS,

¹⁸O_{anhydrite + silicate}, ⁸⁶Sr/⁸⁷Sr_{anhydrite + silicate}) and P013 (clast: ICP-MS). K. Sample PM18 (193-1188A-17R-1, 24 cm): coherent dacite. Bulk rock powder: P015 (XRF, ICP-MS, F, Cl,

¹⁸O_{anhydrite + silicate}, ⁸⁶Sr/⁸⁷Sr_{anhydrite + silicate}). L. Sample PM20 (193-1188A-19R-1, 41 cm): amygdaloidal coherent dacite. Bulk rock powder: P016 (XRF, ICP-MS). M. Sample PM21 (193-1188A-19R-1, 86 cm): weakly altered vesicular, coherent dacite. Bulk rock powder: P017 (XRF, ICP-MS, F, Cl). N. Sample PM23 (193-1188A-20R-1, 95 cm): spherulitic coherent dacite. Powders of separates: P018 (spherulite-rich: XRF, ICP-MS, Cl, F,

¹⁸O_silicate + ⁸⁶Sr/⁸⁷Sr_silicate) and P019 (spherulite-poor: XRF, ICP-MS,

¹⁸O_{anhydrite + silicate}, ⁸⁶Sr/⁸⁷Sr_{anhydrite + silicate}). O. Sample PM26 (193-1188F-6Z-1, 45 cm): weakly altered, spherulitic coherent dacite. Bulk rock powder: P020 (XRF, ICP-MS,
