Saline fluid inclusions in sphalerite from the Broadlands-Ohaaki geothermal system; a coincidental trapping of fluids being boiled toward dryness

Report of a fluid inclusion study of sphalerites from the Broadlands-Ohaaki geothermal system. The findings indicate that brine-filled fluid inclusions do exist in sphalerite from one location, but that their origin is a consequence of local boiling toward dryness rather than introduction of a deep brine.
