The Yimen (Sanjiachang) copper deposits are representatives of Dongchuan type deposits. They are further sub-divided into Shishan-type and Fengshan-type deposits, named after their prototypes according to their geologic occurrence, mineral assemblage and mineralization. The Shishan type is a sulfide deposit of marine exhalative-hydrothermal sedimentary origin, and the Fengshan type is the result of transformation of a Shishan type deposit by later tectonics and hydrothermal fluids. Most of the deposits in this ore field contain minor superimposed cobalt, bismuth, molybdenum, or lead-zinc mineralization.
