It is suggested that the dioritic enclaves and their host granite were derived from the same parental magma that resulted from partial melting of the Neoprot-erozoic depleted-mantle-sourced juvenile crust.

综合岩石学、地球化学和同位素等方面的对比研究,笔者认为八大石闪长质包体属于同源包体,为寄主花岗岩同源母岩浆经结晶分异作用形成的早期产物

The dioritic enclaves and their host granite have positive in εNd(+4.15 and +3.06)values and relatively low (87Sr/86S r)i(0.70412 and 0.70475) with fairly similar model ages tDM(812 M and 944 Ma, respectively.

A REE partition simulation suggests that the Tianzhushan intermediate rocks can be generated by partial melting, in coupling with fractional crystallization, of dioritic gneiss which is similar in chemical compositions to the mafic rocks in the lower crust in North Dabie; partial melting of intermediate grey gneiss which is similar in chemical compositions to the middle crust in North Dabie can generate the Tianzhushan felsic rocks.

REE配分的定量模拟计算结果表明,与基性下地壳相似的北大别基性闪长质片麻岩部分熔融并经过结晶分异能够形成与天柱山中性岩类似的稀土元素组成,而与中性地壳相似的北大别中性灰色片麻岩部分熔融能够形成与天柱山花岗岩类似的稀土元素组成。

Kubusunan granite is chracterized by low87Sr/86Sr initial values and high ε values, indicating its origin partly from mantle rocks. The number of microgranular dioritic enclaves is the direct evidence for crust-mantle magma mixing, thus showing that enclaves are the residual formed from the partly fusing of basic magma.
