碱性玄武岩的双凹型REE配分模式是熔体与单斜辉石、石榴石达到化学平衡或近于化学平衡的结果；

The double-concave shape of REE patterns of the alkali basalt show that the basalt melt had reached equilibrium or quasi-equilibrium with the garnet and clinopyroxene megacrysts.

它是中生代硅酸过饱和并富钾质的火山岩系的产物，其意义可与产于新生代碱性玄武岩系中的晶洞钠沸石对比。

It is a product of volcanic rocks of the mesozoic era over-saturated with silica and rich in potash. it can be compared with geode natrolite that producedin alkaline basalt series of the cenozoic era.
