摘　　要：通过对山东荣城伟德山岩体的暗色微粒包体和寄主花岗质岩石的野外地质，岩体构造环境，特别是岩相学的研究，着重阐述了伟德山花岗质岩浆的混合作用特点和岩相学标志，并首次提出伟德山岩体是二长花岗质岩浆和辉石闪长质岩浆混合作用的产物。Through the studies on field geology, structural environment, especially petrography of dark microgranula inclusions and granitic host rock of Weideshan rock body, Rongcheng, Shandong province, the paper described the characteristics and petrographical sign of the mingling of granitic magma in Weideshan, and first advanced that Weideshan rock body was the result of the mingling of monzogranite magma and pyroxene diorite magma.
