【摘要】 根据沉积建造、岩浆建造将北山地区大地构造演化划分为前地槽阶段（Ar-∈）、地槽阶段（O-T₂）、地台阶段（T₃-J₂）和地洼阶段（J₃-Q），其中地槽阶段O—P₁属地槽期、P₂-T₂属褶皱造山期，D_2-3发生强烈的局部造山运动。对北山地区典型铜矿床（公婆泉铜矿和白山堂铜矿）的成因类型进行了论述。在矿区大量火山岩及斑岩岩石化学组成、微量元素及稀土元素含量分析测试基础上，紧紧扣住矿床地质特征及矿床成矿大地构造背景，从成岩成矿物质来源、矿床类型、铜的富集与成矿机理等方面探讨公婆泉斑岩铜矿形成机制。综合考虑区域大地构造演化史、矿床成因类型、成矿母岩岩石类型及成岩成矿时代来论证北山地区典型铜矿床成矿大地构造背景，结果表明公婆泉铜矿区斑岩型铜矿形成于褶皱造山期、火山热液型铜矿形成于优地槽期，白山堂铜矿形成于地槽期。更多还原

【Abstract】 The geotectonic evolution is divided into pre - geosynclinal phase(Ar-# ), geosynclinal phase(O- T2X platform phase(T3 - J2) and Diwa phase (J3 - Q) in the Beishan area according to sedimentary formation and magatic formation. The dissertation researches into the genetic type of Gongpoquan and Baishantang copper deposit. Base on the majar - elemen, trace - element, race ?element content of a large number porphyry and volcanic rock in the Gongpoquan copper ore district, this dissertation studies minerogenetic mechanism of Gongpoquan porphyry copper deposit on the source of matter, the type of deposit,the enrichment and minerogenetic mechanism of copper. The minerogenetic geotectonic background of typical copper deposits is proved according to the geotectonic evolution,genetic type of deposit, the genetic type of metallogenic mother rock and metallogenic epoch, and the results show: Gongpoquan volcanic rock type copper deposit formed in late eu-geosyncline phase, Gongpoquan porphyry copper deposit formed in orogenic phase, Baishantang copper deposit formed in geosynclinal phase.更多还原
