Abstract

Inverse correlation between homogenization temperature and salinity; temperature of formation changes at near-constant salinity; and low-salinity, low to moderate-temperature inclusion fluids are found in sphalerite formed in limestone. An evolved basinal brine component was recognized by its characteristic temperature (100 degrees to 120 degrees C), freezing point depression (< -22 degrees C), and apparent Ca + Mg/Na > 1. Fundamental chemical requirements for formation of Pb-Zn-Ba-F deposits from metal-bearing basinal brines.--Modified journal abstract.
