摘要: In this chapter I discuss and describe a range of hydrothermal mineral systems that are generated at passive margins, in basin structures intracontinental or back-arc rifts, with without obvious connection to igneous activity, seafloor metalliferous sediments iron manganese oxide accumulations. Passive margins rift-related ore deposits include those known as Mississipi Valley-type (MVT), sedimentary exhalative polymetallic massive sulphides (SEDEX) the Cu-rich stratabound stratiform disseminated sulphides, all which can be broadly grouped under wider family sedimentary-hydrothermal systems.
