| 摘 要： | 滇东北会泽地区位于扬子地台西缘,构造部位属欧亚板块,翻身村断裂带位于该地区中部,构造部位属寻甸-宣威断裂的北段,该断裂带北东方向延伸约57 km,宽0.5 km～2.6 km,2014年的鲁甸地震表明该断裂带仍然是一个构造活动带,为了达到防震减灾的目的,对翻身村断裂运动学的研究具有重要意义。应用小构造解析的方法对翻身村断裂运动序列进行了解析,得出6个变形序列,即①NW-SE构造挤压→②NW-SE构造挤压→③NNW-SSE构造拉伸→④近SN构造挤压→⑤NE-SW构造拉伸→⑥NWW-SEE构造挤压。翻身村断裂同时控制了区内的铅锌成矿带展布,铅锌矿体(脉)沿该断裂的北北东或北东向低级别、低序次层间裂隙充填,并于复合部位出现了相对较好的矿化。

| Abstract: | Fanshencun fault belt in the middle of the west margin of Yangtze platform extends 57 km along NE-SW direction with a damaged width of 0.5 km^2.6 km.Ludian earthquake in 2014 triggered by Fanshencun fault and therefore,it is an active fault in the region.Structural analysis on the deformation sequence of the fault shows that the Fanshencun fault belt experienced 6 stages of deformation sequences:① NW-SE compression;②NW-SE compression;③NNW-SSE extension;④near SN compression;⑤NE-SW extension;and ⑥NWW-SEE compression.Fanshencun fault belt controls the distribution of Pb and Zn deposits in the area and the ore bodies occur in the low rank and low generation interlayer fractures.At the compound positions,mineralization becomes well developed. |
