Rapid, high-precision measurements of boron isotopic compositions in marine carbonates
Malcolm T. McCulloch (1,2), Michael Holcomb (1,2), Kai Rankenburg (2) and Julie A. Trotter (2)
The isotopic composition and elemental abundance of boron (B) in marine carbonates provide a powerful tool for tracking changes in seawater pH and carbonate chemistry. Progress in this field has, however, been hampered by the volatile nature of B, its persistent memory, and other uncertainties associated with conventional chemical extraction and mass spectrometric measurements. Here we show that for marine carbonates, these limitations can be overcome by using a simplified, low-blank, chemical extraction technique combined with robust multi-collector inductively couple plasma mass spectrometry (MC-ICPMS) methods.
