Book excerpt: Fluid inclusions provide the only direct information on the physicochemical conditions of ore-forming fluids, thus they are of immense value in the study of ore deposit genesis. This paper reports results of a fluid inclusion study on sphalerite, galena, calcite, barite, fluorite, and quartz mineral phases at the Gays River lead/zinc deposit in Nova Scotia. The results are interpreted in the context of a multidisciplinary, deposit-scale study that included underground mapping, drill core logging, petrology, whole-rock and mineral chemistry, isotope studies, and geochronology. The fluid inclusion study includes thermometric heating and freezing measurements, gas chromatography, and determination of solute chemistry via analysis of decrepitate mounds. The thermometric data are compared to results of a regional-scale fluid inclusion study that examined fluid evolution both within the area immediately surrounding the Gays River deposit and on a basinwide scale. The data are also evaluated in the context of the thermal evolution of the basin as indicated from organic maturation and clay minerals.
