摘　　要：通过总结南岭及其邻区与斑岩-夕卡岩型铜(钼)矿床有关的10余个中酸性岩体钾(硅)质交代作用及其蚀变岩的地质-岩石学和岩石化学特征,说明了钾(硅)交代作用对含矿岩体原岩命名的干扰和影响.From a sum-up of potassium (silicic) metasomatism of ten more intermediate acidity intrusivesthat related to porphyry-skarn type Cu (Mo)ore deposits in Nanling and its adjoining areas and thegeological, petrographical and petrochemical features of their altered rocks, the auother expounds thatthe potassium (silicic) metasomatism has an effect on the nomenclature of primary rocks of the mineralized intrusives.
