Statement

Trace element geochemistry was determined using quadrupole LA-ICP-MS using a Teledyne Iridia 193 nm laser connected to an Agilent 8900 ICP-MS QQQ mass spectrometer at the NHM, London. A suite of 40 elements were acquired for rutile and 47 elements for apatite. Rutile and apatite grains were located using TESCAN TIMA maps imported into the Chromium 3.1 software. Ablation was performed using a fluence of 3.5 J/cm2 repetition rate of 5 Hz. Background signal was measured for 30s followed by 30s of acquisition time. A 20 µm spot size was used for rutile and 25 µm for apatite dictated by the grain sizes in the samples. Stoichiometric values for Ti47 (59.95 wt.%) and Ca43 (38.5 wt.%) were used as internal standards for rutile and apatite, respectively. Mass spectrometer calibration was conducted using the NIST610 glass standard for rutile and NIST612 for apatite (Jochum et al., 2011). Reference materials BCR-2G and GSD-1G were analysed as secondary standards to evaluate the reproducibility of the data. Literature values used for each glass standard were downloaded from the GEOREM database (Jochum et al., 2011). Rutile mineral references materials R10b, R13 (Luvizotto et al., 2009a) and R632 (Axelsson et al., 2018) and the Durango apatite standard (Chew et al., 2016) were run as unknowns to monitor accuracy and precision. Standard-sample bracketing using these reference materials was performed after ~10 unknown analyses. Data processing and reduction was performed using an offline Microsoft Excel VBA spreadsheet. Signals containing mineral inclusions, notable contamination or low signal-noise ratio were omitted from the final spreadsheet.
