Comment:
Serpentine matrix. B concentrations for samples of serpentine matrix were measured by isotope dilution mass spectrometry (IDMS) at the Department of Terrestrial Magnetism( DTM) (Washington, DC, USA) using the HF-mannitol method of digestion (Nakamura et al., 1992) and positive ion thermal ionization mass spectrometry of Cs2BO[+]2 (Spivack and Edmond, 1986, doi:10.1021/ac00292a010, Xiao et al.,1988, doi:10.1016/0168-1176(88)83016-7). Uncertainties are less than +/- 1% for IDMS measurements. B isotope measurements were prepared and analyzed using methods similar to the IDMS analyses at DTM.
