| 摘 要： | 江西大湖塘地区近年发现了一批大-特大型钨铜多金属矿矿床,矿床类型均为燕山期构造-岩浆热液型,成矿与燕山期花岗岩有关,基底中的成矿元素被活化并参与成矿;矿化受燕山期断裂及其岩体与围岩接触面的控制,根据岩体形成时代、岩石地球化学特征及与矿化的关系判断,细粒花岗岩及花岗斑岩为成矿岩体或成矿地质体;该区的成矿作用与区域燕山期构造-岩浆热液成矿系统直接相关,并受深部作用过程和浅部构造环境的双重控制;其成矿机理是基于成矿系统内部各种物理、化学(生物)作用的耦合,成矿实际上是深部过程背景与表层岩石响应的结果。

| Abstract: | In recent years a batch of large to super large tungsten-copper deposits have been found in succession in Dahutang area.They are all Yanshanian tectonic-magmatic hydrothermal ore deposits and metallogetically related to Yanshaian granite.Ore elements in basement are activated and incorporated in the metallogenic process.Mineralization is both controlled by Yanshanian fractures and contact plane of Yanshanian intrusive bodies and their enclosing rocks.Based on rock-forming times,relation between mineralization and geochemical characteristics of rocks the fine grained granite and granitic porphyry are the oreforming rock bodies or geological bodies.In Dahutang area the metalogenic process is directly related to the regional Yanshanian tectonic-magmatic hydrothermal system and is controlled both by deep processes and shallow tectonic setting.The metallogenic mechanism is the coupling of various physical and chemical （biological） processes within the metallogenic system.In fact the metallogenic process is the result of response of superficial rocks to the deep process background. |
