系统地综述了玄武岩的成因和岩浆源区性质、利用玄武岩判别地幔类型、玄武质岩浆的演化与大陆动力学关系，以及判别构造环境等方面研究的现状。 - The mantle source for the mesozoic mafic volcanic rocks in yanshan area exhibit transition character in space and time : the mantle source components vary from subduction - related metasomatic components and emi components through dominant emi components and slight subduction - related metasomatic components to emi components ; spatially , mantle source of the volcanic rocks show a regular variation trend from an enriched lithospheric mantle with emi - like signatures in the western shandong province through emi and / or subduction - related metasomatic components in yanshan area to subduction - related metasomatic lithospheric mantle in the hinggan - mongolian orogen
燕山地区中酸性火山岩则来源于地壳，与玄武质岩浆底侵作用关系密切。 3燕山地区火山岩源区组分在时空上具有一定的演化规律：在时间上，从早期俯冲交代地幔及emi的参与，经中期以emi占主导及极少量俯冲交代组分的阶段，演变到晚期以emi为主，可能有少量软流圈贡献的组分，再到晚白垩世以软流圈为主。
