摘要
简要回顾了熔体形态学的研究方法,并分别从熔体分数和熔体分布形态两个方面,综合前人在熔体对岩石物理和力学性质的影响领域的主要研究成果,认为在部分熔融初期,熔体分数小,熔体主要分布于孤立的熔体囊内,对岩石的电学性质和力学性质影响不大,但是,对岩石的弹性波波速影响却很明显;随着熔体分数的增大,孤立的熔体囊逐渐连通形成熔体管道网络,岩石的电学性质发生显著变化;当熔体分数增至某一临界数值时,岩石体系结构改变,岩石的力学性质发生突变.
This paper reviews the research methods of the morphology of melt, outlines some important research results about the influence on petrophysics and mechanics in both melt fraction and melt geometry. It makes a conclusion that： （1） during the first stage of partial melting, melt fraction is small, the melt mainly distributes in the melt pockets, and the influence on elastic velocity of rock is obvious~ （2） in the second stage, the melt pockets connect and form a melt tube network with the melt fraction increase, and the conductivity of rock changes a lot; （3） as the melt fraction increases to a critical value as the third stage, the framework of rock system changes, and the mechanics of rock breaks.
