Abstract
On the basis of the geological characteristics of primary gold deposits, with an experiment on modelling the environment of gold mineralization , the evolutionary array and growth mechanism and their relationship with gold mineralization of the crystal forms of pyrite, i. e. pentagonal dodecahedron, octahedron and cube, formed under the different values of fo2, fs2, T (℃), P(Pa) and C (salinity) in the hy-drothermal system are studied. The results show that the crystal form of pyrite is not only related to the temperature L, but also affected by the geochemistry of iron and sulfur which formed pyrite and other physicochemical conditions.Our results promote the study of gold mineralization, genetic and prospecting mineralogy.
