摘要
大吉山岩体的岩石中含有大量的微粒包体，经过对包体的一般特征、结构构造、矿物和化学成分等分析，表明是中基性岩浆与较冷的花岗岩浆不完全混合而成的．据包体与寄主岩石的关系，得出大吉山岩体的成分具有多种混合物质来源．
There are a lot of micro enclaves in the rock of Dajishan rockbody. After an analysis of the general characteristics, the structure, mineral and chemical compositions of the enclaves, it is shown that the emclaves are formed by the incomplete mixure of neutral-basic magma and the cooler granitic magma.Rock-forming material source is concluded according to the relation of the enclave and the hostrock.
