摘　　要：这里主要从成矿地质背景、控矿构造、赋矿火山岩分布、矿床特征等宏观地质现象,结合岩矿石结构的构造与成份等微观特征的深入研究,首次确定了如金沟铜矿区赋矿次火山岩的存在。初步认为其主导矿床成因类型为次火山岩型,在矿区内形成次火山岩型→火山热液型→构造热液型较完整的矿化分带系列。The existence of the ore-forming subvolcanics and leading subvolcanic type copper deposit is confirmed for the first time basing on the analyzing of the profound studies of combining macroscopical geological background,ore-control structure,ore-forming volcanics distribution and ore characteristics with microcosmic rock structure,fabric and contents.,And also indicate that multitype metallogenic zonation of subvolcanic type→volcanic hydrotherm type →tectonic hydrotherm type from hyperbyssal volcanic bodies to country formation.
