摘 要: | 1 Introduction Mo et al. (2005) determined that magma mixing and mingling took place extensively in the Gangdisê magmatic belt around 50 Ma, and argued that magma mixing was genetically related to underplating of mantle-derived magmas beneath that belt. Underplating, as one of the major mechanisms for crustal growth, can occur in the environments of convergent plate boundaries, subduction and collision zones, and in intra-plate settings such as continental flood basalt provinces (Wilson, 19…
