摘要
通过对岩体的野外地质特征、晶体光学与矿物学特征的研究,推断出郭家梁岩带的碱性偏碱性岩属于二长岩—正长岩组合,且其岩浆侵入具有同源性,指出郭家梁碱性岩体地处华北板内吕梁隆起中段,对深入了解华北地块中西部晚中生代的克拉通破坏具有十分重要的意义。
Through the research on the field geological characteristics,crystal optical characteristics and mineralogical characteristics of the rock mass,this paper concludes that the alkalic and alkalescent rocks in Guojialiang Rocks Zone belong to monzonite-syenite association,and their magma intrusion possesses homeology,and points out that Guojialiang alkalic rocks are located in the central section of the Luliang uplift in the North China Block,which possesses great significance on revealing the Craton Destruction in Late Mesozoic in the Midwest of North China Block.
