| Abstract | The causin brecciation in epithermal and mesothermal deposits intimately related to mineralisation. It is therefore necessary to establish both a enetic and descriptive for breccias in this . paper proposes a revision of the genetically-based erected by Sillitoe (1985). The most significant innovation is to distinguish between breccias formed by steady-state hydrothermal processes, and those formed by transient disturbances of a hydrothermal system, by renewed magmatism. This latter process can be particularly important in mineralisation. |
