本文详细阐述了近年来国内外对岩浆混合作用的研究进展,集中在混合作用的验证及地幔物质参与对混合作用的影响。从能量、物质运移的角度认识岩浆混合作用,以揭示上地幔、地壳的信息,并为认识区域构造一岩浆演化提供约束。综合归纳了岩浆混合作用主要的研究方法,系统总结了混合作用发生的规律及主要影响因素,并应用已有理论和数据进行简单的数值模拟,合理解释岩脉的不混合特征。作为壳一幔间物质与能量交换的重要形式,阐述了岩浆混合与底侵作用的关系,并介绍了常见的岩浆混合作用岩石成因模型。最后说明了岩浆混合作用今后的发展趋势和存在问题。
As an important geological process, magma mixing is of great significance in understanding genesis and evolution of magma. In this paper, the latest research advances of magma mixing, especially, validation of mixing process and contribution of mantle material to magma mixing process, were elaborated, magma mixing process were re-recognized from energy and material transfer perspectives, information of crust and mantle was revealed, and constrained conditions of the local structure and magma evolution were proposed. Based on the previous stud- ies, this paper systemically classified the research methods for magma mixing process, summarized the rules and the major impact factors of magma mixing process, attempted numerical simulations on the literature data and theories, and offered a reasonable explanation for the non-mixing attribution of intruding veins. This paper explained the relationship between magma mixing and Under-Plating, which is an important form of Crust-Mantle interchange. By the end, this paper summarized the research directions and potential scientific questions of magma mixing.
