As an important manifestation of continental crust magmatic activity, silicic volcanic eruption is of great significance in studying the formation and evolution of continental crust, and understanding the magmatic processes and dynamic mechanisms. The violent explosive eruption which is usually manifested by silicic volcanic eruption can even cause global environmental and climate change. The contribution and interaction of magma from different sources in open silicic magmatic system is still a hot issue to be further studied. The continuous magma recharge can prolong magma storage time, promote convection in magma chamber, magma differentiation, crystalmelt separation and mush rejuvenation, and is also one of the important mechanisms triggering eruption. Furthermore, magma recharge and crystalmelt evolution processes of silicic magma are also responsible for the diversity of volcanic eruption products. They cause regular variations in eruption products of the same volcano during its eruptive activity, such as crystalrich volcanic rocks, crystalpoor volcanic rocks, composition stratification of volcanic rocks, as well as the resurgent dome and central intrusive rocks. Therefore, magma recharge is an important constraint factor for the evolution of silicic volcanic magma system and volcanic composition diversity, and can also provide important information for active volcano monitoring and disaster assessment. Petrology, geochemistry, isotope and composition variation of minerals (feldspar, quartz, garnet, zircon, etc.), as well as experiments and seismic tomography studies, provide a variety of perspectives to reveal the magma recharge and complex magmatic processes in silicic magmatic systems.
