Abstract：In this paper we introduce several breakthroughs in geodynamic or tectonic issues resulted from studies on ore-systems, and propose that ore-systems can serve as an ideal geodynamic probe. Usually formed in multiple geological processes, ore-systems record complete geological information. Compared to other kinds geologic bodies, ore-systems are more precisely studied through prospecting and/or mining. As a consequence, ore-systems can provide accurate indicators to geodynamic settings and evolution. We set up a preliminary linkage between major ore-systems and geodynamic settings; and propose several important scientific approaches for solving long-standing geodynamic controversies by the study of ore-systems.
