摘要: 金牛厂铅锌矿区的铅锌矿体赋存于NWW向羽状断裂中.研究认为坪箐背斜是区域NW-SE向构造应力长期作用的结果,为矿区的主要控矿褶皱.NE向的关仓箐逆断层为矿区的导矿构造,NWW向次级张扭性断裂为矿区的主要容矿构造.矿区内矿体受构造控制明显,深部和边部具有良好的找矿前景.Abstract: The orebodies in the Jinniuchang Pb-Zn deposit occur in the NWW-trending plumose fractures. Study shows that the Pingqing anticline, which is the results of regional NW-SE structural stress, serves as the main ore-controlling structure. The NE-trending Guancangqing reverse fault is the passage-way for ore fluid. The secondary NWW-trending tenso-shearing fault is the main host structure. The orebodies are obviously controlled by structures in the orefield, therefore the deep and surrounding areas are prospective for ore-searching.
