摘要
在把握成矿系列“三同”基本前提和“五多”基本特征的基础上 ,把太行山—燕山造山带与中生代花岗岩有关的矿床划分为 6个成矿系列 ,并探讨了各成矿系列主要地质特征、稳定同位素特征、成矿热液性质及其物理化学条件 ,指出各成矿系列具有不同的特征 ,岩浆岩、地层、断裂构造等对成矿系列形成都有控制作用 ,成矿物质既来源于围岩 ,也来源于花岗质岩浆 ,并且在造山作用过程中 ,壳幔演化对各成矿系列有不同的贡献。
Lying in the central part and northern margin of the Sino\|Korea plate,the Taihangshan\|Yanshan orogenic belt is characterized by iron,copper,molybdenum,gold,silver,lead,zinc and uranium deposits.Based on three “identical” basic prerequisites(the same geological environment,the same geological era and the same geological function)and five “multiple” basic characteristics(multiple ore\|forming elements,multiple ore deposit types,multiple ore\|forming patterns,multiple ore\|forming positions and multiple ore\|forming stages)of the metallogenic series,the authors have divided the ore deposits related to Mesozoic granites in the Taihangshan\|Yanshan orogenic belt into six metallogenic series,viz.,the Fe(AuCi) metallogenic series related to intermediate\|shallow\|seated magmatic intrusion,the MoCuFeZnAgPb metallogenic series related to intermediate(slightly acid)\|acid intermediate shallow\|seated\|superhypabyssal magmatic intrusion,the NbTaLiBe metallogenic series related to peraluminous acid magmatic intrusion,the AgPbZnMn(Au) metallogenic series related to continental volcanic\|subvolcanic activity,the UMo metallogenic series related to continental superhypabyssal volcanic activity,and the stratabound\|transformed Au metallogenic series somewhat related to magmatic\|hydrothermal activity.On the basis of such features of various metallogenic series as the major geological characteristics,the stable isotope characteristics,and the properties of ore\|forming hydrothermal fluids as well as their physical\|chemical conditions,the authors have reached the following conclusions:(1)the six metalloenic series have different characteristics;(2)magmatic rocks,strata and faults all played the controlling role in the formation of metallogenic series;(3)the ore\|forming materials were dervied from both wall rocks and granitic magma;(4)in the orogenic process,the crust\|mantle evolution made different contributions to different metallogenic series.
