Description

Data Set S1. Proportion of minerals determined by XRD in all whole rock and mineral separates. Data Set S2. Summary of electron probe microanalysis (EPMA) acquisition parameters. Data Set S3. Full EPMA dataset of major elements and Cl for halogen-bearing minerals including amphibole, iddingsite/serpentine, chlorite as well as thomsonite and prehnite. Data Set S4. Summary of irradiation parameters including neutron fluxes calculated from standards and monitors (Hb3Gr, scapolites, Shallowater), vertical variation in J, ɸtherm and ɸfast and associated linear regressions used to interpolate to sample positions. Data Set S5. Full neutron-irradiated dataset including Cl, Br, I, K, Ca, Ba and U abundances and natural noble gas abundances (Ar, Kr, Xe) and isotopes (40Ar/36Ar). Data Set S6. Full un-irradiated dataset including, He, Ne, Ar, Kr and Xe abundances and isotopes including 3He/4He. Data Set S7. LOI data measured on whole rock samples.
