“区域熔融”(Zone melting)是五十年代初用于金属和有机质纯化方面去除杂质的一种部分熔融作用。1957年P.S.哈利斯(Harris)将这一概念引进地质界,用来解释地慢物质分异、岩浆上升机制和富钾玄武岩岩浆的成因。1959年以来苏联一些地球化学工作者用球粒陨石硅酸盐相的区域熔融实验来论证地慢分异和地球壳层的形成机制。1970年发表了“地慢物质分异过程中元素分离的物理-化学模型” Zone melting is a partial melting effect used to remove impurities in the purification of metals and organic matter in the early 1950s. 1957 P.S. Harris introduced this concept to the geologic field to explain the slow material differentiation, the mechanism of magmatic ascent, and the genesis of potassium-rich basaltic magmas. Since 1959, some geochemical workers in the Soviet Union have used regional melt experiments of chondrites and silicate phases to demonstrate the mechanism of slow differentiation and formation of the earth’s shell. In 1970, he published the “Physical-Chemical Model of Element Separation in the Process of Subsoil Material Differentiation”
