| 中文摘要: |
| 二道河银铅锌矿是近几年来大兴安岭北段新发现的大型有色金属矿床,文章根据矿床所处区域地质背景、区域地球化学和地球物理特征以及矿床地质、物化探异常特征,对二道河银铅锌矿成矿条件、成矿规律进行分析研究,建立了该矿床的地质、物化探找矿模式,认为矿床成因为接触变质充填交代及断裂构造控制的中低温热液充填交代型矿床。夕卡岩化、大理岩化、青磐岩化、黄铁矿化、硅化等蚀变综合特征与成矿关系密切。 |
| 英文摘要: |
| The Erdaohe silver-lead-zinc deposit is the largescale nonferrous ore deposit newly discovered in the north of great Khingan mountain range in recent years. The paper analyzes the metallogenic conditions and regularities of Erdaohe silver-lead-zinc deposit based on the study of geological background, regional geochemical and geophysical characteristics, deposit geology as well as geophysical and geochemical abnormal features, the geological,geophysical and geochemical prospecting models are built herein. The study result shows that the genesis of the ore deposit belongs to the contact metamorphic metasomatic filling type, and low-mediumtemperature pyrometasomatic deposit controlled by fault structure. The country rock alteration closely related to mineralization is skarnization, marbleization, propylitization, pyritization and silicification. Finally, the paper proposes some suggestions for regional prospecting. |
