摘要
江西武功山片麻岩 ,前人存在两种观点 :混合成因和岩浆成因。近年来 ,作者等人 通过 1:5万区调 ,对武功山片麻岩取得了一些新的认识 ,认为武功山片麻岩是岩浆成因 ,属岩浆多次脉动形成的气球膨胀式强力侵位机制。
According to Wugong mountain's gneiss in Jiangxi,the predecessors have two opinions:mix cause of formation and magma cause of formation.Recently,the author and others have obtained some new knowledge of Wugong mountain's gneiss by regional investigation (1∶5).They think Wugong mountain's gneiss is magma cause of formation,which belongs to balloon's expansional mechanism of heavy emplacement formed by several pulses of magma.
