| 中文摘要: |
| 广龙坡铅锌矿位于扬子准地台和华南褶皱带的结合部位,为湘黔铅锌成矿带的重要组成部分。对矿床地质特征及成矿地质条件分析表明,矿床明显受一定的地层层位、围岩岩性、岩相古地理及断裂构造作用所控制；其中,断裂构造作用是矿床形成的主导因素,贯穿于整个矿床的形成过程。具有多期活动的保铜玉区域性同沉积深大断裂对广龙坡铅锌矿床的形成具有控岩和控矿的“双控”特性。 |
| 英文摘要: |
| the Guanglongpo lead-zinc deposit, situated in the junction between the Yangtze paraplatform and South China fold belt, is an important section of the western Hunan-eastern Guizhou Lead-Zinc metallogenic belt. By analying geological characteristics and metallogenic condition in the Guanglongpo lead -zinc deposit, it’s showed that the deposit is obviously controlled by stratigraphic horizon, surrounding rock properties, lithofacies paleogeography, and fracture tectonism. Among them, fracture tectonism is the dominant factor for deposits’ formation , and fracture tectonismlasted throughout the entire formation process of lead-zinc mineralization. The baojing-tongren-yuping regional synsedimentary deep fault with multiple stages of activity has double control characteristics for Guanglongpo lead-zinc deposit, including rock-controling and ore-controlling. |
