摘　　要：通过闹枝沟岩体中的包体 (脉体 )的野外地质学特征及与寄主岩石的关系 ,阐述了闹枝沟岩体岩浆混合作用的野外地质学证据 ,首次确定闹枝沟岩体岩浆是由基性幔源岩浆和酸性壳源岩浆混合而成 ,岩体成因类型属壳幔混合型 。On the basis of the relationship between field geological evidence of inclusions (veins) of the Naozhigou rock body and its host rock,the geological evidence of mingling of magma of the Naozhigou rock body is expouded in this paper It is determined for the first time that magma of the Naozhigou rock body is formed by mixed basic mantle-derived magma,which belongs to mixed crust-mantle type in genesis,and provide a preliminary field clue for distinguishing granite of mingling of magma in genesis
