| 摘 要： | In the present paper, it is suggested that the bay or lagoon areas of post-reef of stromatolith, and the bathyal areas of pre-reef were water basins where copper ores were deposited, the former corresponding to syngenetic dolomite facies of post-reef bay or lagoon environment and the latter to black shale-dolomite facies of pre-reef building.It is concluded that the stratiform copper deposits are genetically of diagenesis and closely related to stromatolith reef, but not directly to the tuff in sedimentary origin.
