In the light of tectonic evolution stage and metallogenesis, these metallogenic system ( assemblage ) could be classified as follows : ( 1 ) the pre - divergent metallogenic system in the southwest margin of north china paleocontinent in the archean - meso proterozoic : dongdashan iron, jinchuan nickel - copper. ( 2 ) the divergent metallogenic system in the northern margin of the qaidam paleoplate in the middle - late proterozoic : huashugou - liugouxia iron.
