- For this investigation, a New Wave 193 μm eximer laser coupled to a 7700 agilent ICP-MS was used. The laser was equipped with a 2-volume cell. Each fused disc was ablated for 60 s with a laser spot-size of 150 μm in diameter, a pulse rate of 20 Hz, and measured fluence of 8 J/cm2. As carrier gas a mixture of He and Ar was used with a flow rate optimized for highest sensitivity. For calibration three reference materials were used. Two of these were manufactured and validated in-house at the Bureau Veritas laboratory, the third one was the OREAS 134b standard reference material.

- An Agilent 7500c quadrupole ICP-MS coupled with a New Wave 193 µm excimer laser was used for analyses, with 35 µm spot-size, a 16 Hz repetition rate and a fluence of 7.8 J/cm2. The background was measured for 20 s; the samples were analysed for 20 s. The NIST SRM 612 and NIST SRM 610 glasses were used as reference materials for fluorite. A stoichiometric value of 51.1 wt.% for Ca [74] was used as the internal standard for fluorite. Elemental concentrations, 1 sigma errors and minimum detection limits were calculated using GLITTER (Version 4.4.4, On-line Interactive Data Reduction for LA-ICPMS (Macquarie Research Ltd., Sydney, Australia) using the protocol of Griffin et al. [75]. For each element, the limit of quantification (LOQ) was set to three times the limit of detection (LOD). Signals lower than LOQ were not considered for further interpretation. The following isotopes were measured (typical LODs in ppm in brackets): 23Na (1.28), 29Si (43.8), 42Ca, 44Ca at 10 ms integration time each and 7Li (0.11), 24Mg (1.08), 26Mg, 39K (1.18), 55Mn (0.13), 57Fe (2.8), 66Zn (0.41), 71Ga (0.02), 73Ge (0.08), 74Ge, 85Rb (0.005), 88Sr (0.006), 89Y (0.008), 90Zr (0.017), 93Nb (0.01), 115In (0.008), 118Sn (0.07), 137Ba (0.06), 139La (0.01), 140Ce (0.01), 141Pr (0.005), 146Nd (0.03), 147Sm (0.04), 153Eu (0.005), 157Gd (0.002), 159Tb (0.003), 163Dy (0.03), 165Ho (0.004), 166Er (0.01), 169Tm (0.005), 172Yb (0.02), 175Lu (0.008), 178Hf (0.014), 181Ta (0.0035), 208Pb (0.021), 232Th (0.01), 238U (0.005) at 20 ms integration time each.
