同化混染

辉绿岩具有富集型Nd、Sr同位素组成，且变化范围大，是岩浆源区同化混染作用的结果。

The diabases have riched type Nd , Sr isotopic composition and have great varying range , which is the result of action together both magma source and contamination .

成岩作用是分离结晶和同化混染联合作用。

The main diagenesis is fractional crystallization assimilation and contamination .

锶、铅、氧同位素的初步研究结果对岩浆的幔源性质及所经受的同化混染作用提供了一些线索。

The preliminary results of strontium . lead and oxygen isotope studies has provided some clues to the mantle origin of the magma and to the assimilation and hybridization it undergoes .

白榴玄武岩为次生岩浆冷凝产物，是原生岩浆分离结晶约14%的橄榄石、辉石堆积岩，又同化混染了约28%的花岗岩所形成。

Leucite basalt was solidified by secondary magma , which was produced by fractional crystallization of a small amount ( 14 % ) of accumulative rock from primitive magma and assimilation of granite ( 28 % ).
