摘　　要：位于吉林省安图县东南的石门岩体中,含有大量细粒、斑状闪长岩包体,通过对其形态、产状及特征,特别是包体的结构、矿物成分及矿物生长习性等岩相学特征的研究,初步确定石门岩体岩浆至少是由酸性、基性两种不同成分的岩浆在未完全结晶状态下相互混合形成,首次提出该岩体具岩浆混合花岗岩特征,为浆混成因花岗岩。There are large quantities of fine-grained,porphyritic dioritic enclosures in the Shimen rockbody,southeastern part of Antu County,Jilin Province Through the study on the form of the enclosures,mode of occurrence,characteristic,texture,mineralogical composition and mineral growth habit,it is preliminarily definited that the Shimen magma is at least composed of the acidic and basic magma in a complete uncrystallized state,and proposed for the first time that the rockbody has some characteristics of the migmatitic granite,belonging to mixed magmatic granite
