摘要
Along with the evolution of the earth crust, in the south of Kangdian Axis the polycyclic rifting occurred: Ptd-Ptk, Jinshajiang continental margin sea type aulacogen, Ptk2Dongchuan-Yimen intercontinental aulacogen, Z Chengjiang postorogenic rift and T3-E1 Kangdian continental rift. In these rifts respectively produced Dahongshan-Lala type volcanic-sedimentary-metamorphosed/hydrothermal sedimentary Cu-Fe deposits. Dongchuan-Yimen type, Lanniping type and Dayao-Mouding type sedimentary-reworked copper deposits, which form the storeyed texture whose geochemistry of the trace elements, isotopes of S, Pb, H, O, C. ore-forming fluid and organic matter were regularly evolved with the crust evolution.
