Magma crystallization

The research shows that the formation of two different evolutional trends is related to the types and proportion of fractional phases during magma crystallization differentiation .

研究表明这两种演化趋势的形成与岩浆结晶分离矿物相的种类及其比例有关。

The characteristics of its occurrence , the electron microprobe analyses of albite in snowball texture and other evidence indicate its genesis of magma crystallization differentiation .

雪球结构的产出特征、雪球体中钠长石的电子探针分析结果以及其他间接证据都说明，雪球结构是在岩浆结晶分异过程中形成的。

The MA type is further divided into two subtypes of basaltic magma crystallization ( BMA ) and ultramafic magma crystallization ( UMA ) .

MA型可分为玄武质岩浆结晶（BMA）亚类和超镁铁质岩浆结晶（UMA）亚类。

Then , the authors point out that there in two igneous rocks formed from the same parent magma at the same crystallization stage are 7 essential patterns of concentration relationship between two elements ;

指出：对同源同结晶阶段岩浆岩，元素含量关系有7种基本型式并遵守同一关系式。

The magma might undergo fractional crystallization of olivine , clinopyroxene , hornblende and weak plagioclase during the diagenesis process , which however is not obviously contaminated by crust materials in the emplacement process .

成岩过程中岩浆经历了橄榄石、单斜辉石、角闪石等暗色矿物以及少量斜长石的分离结晶作用，岩浆侵位过程中没有受到地壳物质的混染。

This suggests that the magma supply controlled by spreading rate dominates the ridge crust temperature and magma crystallization depth .

因此，受控于扩张速率的岩浆供应控制了洋壳温度和岩浆结晶深度。

When the magma is in the course of rising it should be hybridized a little by the crust substance , the magma rises from the source to emplacement at least experiences twice magma chamber fractional crystallization process .

岩浆在上升过程中受到过较低程度的地壳物质的混染，岩浆从源区上升到就位至少经历了两次岩浆房的分离结晶过程。
