Abstract

Four large and superlarge copper-multimetal ore deposits hosted in the Mid-Proterozoic Zhartaishan Group along northwestern margin of North China Plate are stratabound hydrothermal sedimentary deposits, and these deposits formed in mid-late stage of the Mid-Proterozoic Langshan-Zhartaishan rifting system. Four necessary conditions are proposed for the formation of these large and superlarge ore deposits: (i) favorable geological background and tectonic environment; (ii) abundant sources of metallogenic material; (iii) favorable sedimentary lithofacies and paleogeographic conditions; (iv) sudden change events during metallogenic processes.
