Note: Fluid composition data (ppm) obtained by laser ablation ICP-MS analysis of individual fluid inclusions. Data presented represent mean values for a fluid inclusion assemblage in which several inclusions are inferred to have been co-trapped.

*N = Number of inclusions measured from each assemblage.

^†Sal. = Salinity (wt% NaCl equivalent).

^§T_h = Homogenization temperature (°C).

^#N.D. = Not determined.

< No results above the limit of detection; the value given is the minimum limit of detection recorded for an inclusion analysis in that assemblage, as the best estimate of the maximum concentration for that element.
