SIGNIFICANCE OF TRACE ELEMENT PARTITION BETWEEN OCELLI-MATRIX OF OCELLAR BIOTITE-PYROXENE-SYENITE, YUANGYUAN, HEBEI
微量元素在河北阳原球状黑云辉石正长岩的球体和基体间分配的意义

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.
