Abstract

The problem of mineral association and mineral paragenesis in ore deposits has been the subject of much discussion. The attempts at a rational explanation have, however, been largely unsuccessful since they were not based on sound physical-chemical principles. A new attempt is made in this paper, and it is shown that the temperature and the fugacity (f) of O, S and CO (sub 2) in ore-forming fluids at the time deposition of the vein minerals largely control the mineralogy of ore deposits. fs (sub 2) -fo (sub 2) -T diagrams showing the stability fields of sulfides, oxides, and sulfates of nineteen metals are developed as well as fs (sub 2) -fo (sub 2) -fco (sub 2) diagrams showing the stability of these compounds and of carbonates of the respective elements. The diagrams are based on recent compilations of thermochemical data; they are used in the second paper of this series to define the approximate composition of ore-forming fluids and the relationships between temperature, pressure, and mineralogy in hydrothermal ore deposits.
