Through the systematical study of petrology, petrochemical and geochemical characteristics, the author concludes that it is an alkali syenite formed inside plate. The syenite,together with basalt, diabase dyke inside the basin forms a speci...

该正长岩为形成于板块内部的碱性正长岩，它与盆地内部的二叠纪玄武岩、辉绿岩岩墙一起构成了一套发育于裂谷性盆地的岩浆岩组合，说明二叠纪时塔里木盆地处于裂谷构造环境。

The existence of MORB type tholeiite depleted in LREE(TH1) demonstrates that some pieces of ocean crust may be involved there.

其中轻稀土亏损的洋中脊型拉斑玄武岩（TH1）的存在显示部分洋壳残片的可能卷入。

Through the restoration of the metamorphic rocks, we conclude that the protolith are principally volcanic rocks. The volcanic rocks in the area evolved from the tholeiite series to the calcalkaline series, along with some terrestrial clastics.
