Disclosed is a localization method for concealed metallogenetic rock and ore body based on a rock- and ore-controlling preexisting structural model in the present application, relating to the field of ore deposit exploration, and including the following steps: determining a preexisting structure controlling porphyry metallogenic system according to geological data of mining area; and respectively determining spatial and temporal distribution regularity of metallogenetic rock and ore body. In the present application, the spatial and temporal distribution regularity of metallogenetic rock and ore body is determined respectively according to different attributes, the model is trained in combination with a qualitative index of the preexisting structure indicating the localization of metallogenetic rock and ore body, and a spatial localization is carried out based on the model, improving the accuracy of the concealed metallogenetic rock and ore body for the spatial localization.
