Abstract Based on the special geomorphology of basin-ridge structure, complex structural intersection, inheritance and continuity of multi-stage NW- and N-S-trending ore-forming structures, the control of Mesozoic granite belt and volcanic rock zone on mineralization and the unique structural trend of NW-runing geophysical anomaly, the authors confirm the existence of NW-trending tectonic-metallogenic belt on the right bank of Heilongjiang River. Many deposit examples indicate that the multi-stage NW-trending tectonic belt has several metallogenic functions like rock-controlling, ore-controlling, ore guide and host. The horizontal zonation of deposits/orebodies is obvious, which provides theoretical basis for exploration prediction on the right bank of Heilongjiang River.
