摘要
东峰顶金矿床成矿过程经历了热液期和表生富集期.矿石品位与氧化程度有关.矿质来源于燕山晚期岩浆活动触发的华北地台基底含金矿源层.它属于中温岩浆热液型矿床.区域构造派生的近南北向断裂,控制着金的定位.文中还探讨了成矿模式和找矿方向.
During its formation, the Dongfengding gold deposit went through two stages: hydrothermal and supergene emichment. The gold content of ores is closely related to intensity of weathering. Oreforming materials originate from basal gold-bearing source bed of Notrh China Platform activated by the late Yanshanian magmatic activities. The deposit belongs to the mesothermal magmatic-hydrothermal type. Gold mineralizations are controlled by NNE-striking fractures derived from regional tectonics. Mineralization pattern and ore exploration guides are also discussed.
