Sediment hosted Stratiform Copper Deposits (SSC) are one of the most important copper suppliers around the world and are also significant sources for Co, Ag, Pb, Zn, U, Ag and PGE. They normally occur as sulfide disseminates in restricted layers within a sedimentary sequence but do not necessarily follow sedimentary bedding. Most SSCs are formed during or at the late stage of host rock lithification (diagenesis) by low temperature, intermediate to high salinity and sulfur rich basinal fluids which circulated in the footwall red bed sequences so as to acquire ore forming elements such as Cu and S. Metal (copper) precipitation is primarily induced by chemical reduction of the upward migrating basinal fluids by in situ reductant in the hanging wall sediments or mobile hydrocarbon within the red beds. Some of them may have been altered and remobilized during regional deformation or metamorphism later on. Supergiant sediment hosted copper mineralization may have been facilitated by global events such as supercontinent breakup, hot and arid paleoclimate, Great Oxidation Event, glacial events and magnesium rich ocean waters.
