摘　　要：广东中生代与壳幔岩浆活动有关的成矿作用十分强烈,多期成矿作用明显.在前人工作的基础上,根据矿床的成矿时代、成矿地质构造环境、主要成矿作用及形成的矿床组合,将中生代与岩浆作用有关的矿床厘定为6个矿床成矿系列:1)云开与印支期岩浆活动有关的铌、钽、磷、铁矿床成矿系列;2)粤北与燕山期花岗岩有关的有色金属、稀有金属、贵金属、非金属、铀矿床成矿系列;3)深大断裂带与燕山期基性-中酸性侵入岩有关的铜、铅、锌、金、铁、钼、钨、水晶、砷、硫铁、钒、钛矿床成矿系列;4)深变质带与区域变质、动力变质及燕山期花岗岩类有关的金、银矿床成矿系列;5)沿海与燕山期火山-侵入活动有关的铁、铜、金、银、铅、锌、钨、锡、钼、铌、钽、硫铁、水晶、萤石、叶蜡石、重晶石矿床成矿系列;6)阳春-罗定与燕山晚期壳源花岗岩类侵入活动有关的锡、钨、钼、铜、铁、铅、锌、银矿床成矿系列.论述了各成矿系列的基本特征,并对成矿系列形成的构造背景和成矿作用的时空分布及演化规律进行了探讨.The obvious multi-stage mineralization related to the Mesozoic crust-mantle magmatism is strong in Guangdong region.On the basis of previous work,the deposits related to the Mesozoic magmatism can be divided into six metallogenic series in terms of metallogenic ages,tectonic environment,main process and deposit associations,namely,1)N b,T a,P and Fe deposits related to Indosinian magmatism in Yunkai area;2)nonferrous,rare,precious metals,nonmetal and U deposits related to Yanshanian granites in northern Guangdong depression;3)C u,P b,Z n,A u,F e,Mo,W,A s,V,T i,crystal and ferrous sulfide deposits related to Yanshanian intermediate acid-basic intrusive rocks along deep fault zones;4)Au and Ag deposits related to regional,dynamic metamorphism and Yanshanian granites;5)F e,C u,A u,A g,P b,Z n,W,Sn,Mo,N b,T a,ferrous sulfide,crystal,fluorite,pyrophyllite and barite deposits related to Yanshanian volcanic-intrusive activity in coastal region;and 6)Sn,W,Mo,C u,F e,P b,Zn and Ag deposits in Yangchun-Luoding area related to Late Yanshanian crust-source granites.The basic characteristics and forming tectonic backgrounds of each metallogenic series are discussed followed by the temporal and spatial distribution and evolution law of mineralization.
