Research Progresses on Sediment-hosted Stratiform Copper Deposit
摘要
Abstract
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.关键词
