| 摘 要： | 本文对南秦岭东江口岩体中的闪长质包体的主量元素，微量元素地球化学特征及包体形成的温度和压力条件进行分析，揭示出闪长质包体与寄主岩体是同源的混溶包体。根据新的成因解释，认为不混溶包体的形成机理是由均一岩浆在演化过程中长英质岩浆和铁镁质岩浆有序化的结果。在有序化过程中，其具体过程可能是复杂的

| Abstract: | In this paper based on the research for the chemical compostions,geochemical features of trace element and forming temperature and pressure of dioritic enclaves in Dongjiangkou pluton, it is reveals that the enclaves are homologous with host pluton,and are liquid immiscible ones.Besides, it is indicated the forming mechanism of enclaves as a resulted of the ordering of felsic and femic end members which may be complex during the evolution of homogeneous magma. |
