| −4.1 ± 4.2 ‰ | −8.9 / −1.2 ‰ | 3 | secondary smectite (< 2 µm) Mean and standard deviation recalculated from 3 analyses, -8.9 to -1.2 (R03 368 m -2.1; R05 408 m -8.9; R07 466 m -1.2). 24, 10 and 21 mg/kg B; formed at 63, 60 and 90 °C; calculated fluids +18.9 to +25.4 ‰ (Williams et al., 2007 equation, poorly suited to the high pH of the crater fill according to the authors). Published mean -4.07 ‰. Tetrahedral boron of R05: -10.9 ‰. | Muttik et al. (2011), Boron isotope composition of secondary smectite in suevites at the … |
