Metallogenic epoch is one of the main weak points in the study of metallogenic regularity and prediction in Jilin Province. Study on the metallogenic epoch can not only enrich the study content of metallogenic regularity and prediction, which is helpful to scientific decision-making during field work and reduce the prospecting cost, but also promote new breakthroughs in mineral exploration. This study reached three conclusions through the interpretation of 19 cases, integrating new data and the regional mineral resources metallogenic evolution. The conclusions are as follows:��Taking the metallogenic epoch as the main axis, Jilin Province experienced three different stages of mineralization, i.e., "cratonization","Central Asia orogenic belt" and "Western Pacific continental margin volcano arc and basin ridge structure". �� The ore-controlling structure is represented by "structure controls the basin, the basin types control the phases and the phases control the deposits", "structure controls the magma, the magma controls the phases, and different phases form different ores", "structure controls the types, different types form different deposits, deposits determine the ore body". �� During recent years, new findings of metallogenic epoch, new minerals, new types, new areas, and new concealed ore-bodies indicate that there is great prospecting potential in this area.
