摘　　要：Mafic"intrusive rocks",distributed greatly within Dongchuan strata-bound copperfield and really comprising volcanic,subvolcanic and volcano plutonic rocks,should be termed as volcanic-intrusive complex(VIC).Geology and geochemistry of Jinningian VIC and its relation to Cu ores reaffirm that VIC play an important role in mineralizations,which are not only vein bonanzas deduced from coose beds,but also new orebodies occurred within VIC.Bonanzas of superposing-reworking type and orebodies of magmatic liquation-differentiation type in the depth are suggested to be found in the largely developing VIC area.
