| 摘 要： | 河北阳原辉石岩-正长岩杂岩体的球状黑云辉石正长岩是岩浆不混熔的产物。本文研究了微量元素、REE在球状岩石的球体相—基体相间的分配。提出控制元素在不混溶的两液相间分配的三种因素,建立了分配系数D_(M/O)~i与不混溶两液相的相对聚合度(NBO/T)_(M/O)之间的函数关系。这些研究可用于区分岩浆不混溶作用与其他作用,确定岩石成因。

| Abstract: | The ocellar biotite-pyroxene-syenite from pyroxenite-syenitec omplex, Yuangyuan, Hebei, is production of silicate liquid immiscibility. The partition for trace elements and REE in ocelli-matrix of ocellar biotite-pyroxene-syenite is investigated, The paper points out that three factors control partition of elements in immiscible melt-melt, and establishes the relationship between relative polymerizatione of the two immiscible melts (NBO/T)_(M/O))with element partition cofficients(D_(M/O)) The results may be used to distinguish silicate liquid immiscibility from other processes and to investigate geneses of rocks. |
