  1. Analyses are shown in wt% normalised to 100%; ‘b.d.l.’: below detection limit; ‘tr.’: means that a peak has been recognised but is too close to the detection limit of the instrument for the analyte to be reliably quantified. The values should have a precision (a measure of reproducibility) of c. ±1–2% relative to copper, c. ±5–10% to the major alloying elements and c. ±10–30% to the remaining minor/trace elements 61. A secondary standard (C2) was used to test for the accuracy and precision of the instruments.
