摘　　要：In order to better understand the role of post-collisional mafic magmatism at convergent plate boundaries in revealing the earth’s evolution,this paper has systematically summarized the research history of post-collisional mafic magmatism,different types of collision and their influence on the nature of orogenic mantle,the concept and implication of post-collisional magmatism,and the relationship between post-collisional mafic magmatism and orogenic mantle evolution and mineralization.Post-collisional mafic igneous rocks are not only the direct records for studying the nature and evolution of orogenic mantle,but also the important carriers for regional mineralization.However,the type and quantity of the crustal materials involved in modifying the overlying lithospheric mantle during collisional orogeny,the process and mechanism of such modification,and the major control factors and mechanism of mafic magmatism-related mineralization during the post-collisional period are the main contents and direction of future researches in this field.Therefore,the study of post-collisional mafic magmatism is of significant implications for developing the theory of plate tectonics.
