22 Dec 1967 | | Journal: | Science, 158 (3808), 1580-1582 | | Abstract: | Solubilities of sphalerite (ZnS) and galena (PbS) were determined at 300 degrees to 500 degrees C and 1000 bars total pressure in a chemical environment buffered by silicate mineral equilibria. Chloride solutions and muscovite-bearing assemblages characteristic of hydrothermal wall-rock alteration were used; weak acidities at temperature were therefore involved. The metal concentrations encountered tended to be higher than those observed in high bisulfide-H(2)S systems at neutral to weakly basic pH used in most previous experimentation; the chemical conditions of the work, although not completely satisfactory, are geologically more realistic than previous experimentation done in the basic-pH region. | | Source: | PubMed, pmid17816630 doi: 10.1126/science.158.3808.1580 | | Services: | Forum | Review | Favorites | |
