Its primary magma is high MgO tholeiite.
原生岩浆是高镁拉斑玄武岩浆。
The basalt belongs to the sub-alkaline tholeiite series.
玄武岩属于亚碱性系列中的拉斑玄武岩。
The compositions of major elements from the rocks are consistent with those of basalt and have evolutional current of tholeiite.
岩石的主量元素组成和玄武岩一致,并且具有拉斑玄武岩演化趋势。
All of above characteristics show that the Qingshuiquan basalt is continent tholeiite, rather than a component unit of ophiolites.
这些特征显示大陆拉斑玄武岩的特征,不是蛇绿岩组成单元。
Therefore, the element ratios can be applied to the study of trace element characteristics of rocks in the tholeiite source region.
因此研究拉斑玄武岩源区岩石中的微量元素特征可以采用元素比值的方法。
