1 data sources, whether compiled from studies or from single analytical method, and arranged chronologically: INAA = instrumental neutron activation analysis, LA-ICPMS = laser ablation-ICPMS.
2 reference average reported to number of significant digits observed in most precisely measured data from literature sources.
3 JUB average calculated from number of sample decompositions reported in Table 1 and reported to three significant digits only for illustrative purposes (see Section 5 regarding analytical precision).
* values greater than reference average considered to include significant contributions from interfering molecular species, arising from high major element contents (Mg, Al, Ca, Mn, Fe).
