Based on the theory of the ore formation rate, locations with high temperature changes and fast pore fluid flow are conducive to the formation of ore bodies (Hobbs et al., 2008, Zhao et al., 2009). The ore-forming structure is closely related to the formation of the ore body. The location of the ore body depends on different geological structures.
