| 摘 要： | 福来厂铅锌矿床位于黔西北垭都—蟒硐铅锌成矿带西南部，夹持于天桥与猫猫厂两个铅锌矿床之间，矿床（体）分布严格受构造控制。运用矿田地质力学理论和方法，对福来厂铅锌矿区进行大比例尺构造剖面精测和典型的控矿构造力学性质鉴定以及不同方向断裂、褶皱构造筛分，研究认为自印支晚期—喜马拉雅期以来该区主要经历了三期构造活动，其主压应力方向分别经历了北西向→北东向→近东西向的转变过程，认为矿床的导矿、配矿、容矿构造分别为矿区棋盘格式构造、北东向断裂（倾向北西）与北西西向断裂及其下盘背斜翼部的层间断裂带，此外，矿区存在北西向（倾向北东）破矿构造，明显切割、错移矿体，控制着矿体的空间定位。综合上述，文章在总结了构造控矿规律的基础上，建立了该矿床成矿构造体系，为找矿勘查和矿床成因研究奠定了基础。

| Abstract: | The Fulaichang lead-zinc deposit (FL-ZD) is located in the southwestern part of the Yadu-Mangdong Pb-Zn Metallogenic belt in northwestern Guizhou, China,Which is suited between the Tianqiao lead-zinc deposit and the Maomao lead-zinc deposit, and the distributions of the deposit and its ore bodies are strictly controlled by the structure. Based on the theory and method of geological mechanics of ore-field, the large scale fine survey of structural section and the typical identification of ore-controlling structural mechanical properties, as well as the screening of faults and fold structures in different directions in the lead and zinc mining area of Fulaichang mining area were made. It is believed that since the late Indosinian-Himalayan period, there have been three periods of tectonic activities in this region, and the main compressive stress direction has experienced the transition from NW to NE to near EW respectively. Based on analyzing the ore-controlling characteristics of folds and faults in the mining area, it is concluded that the ore-guiding structure, ore-distribution structure and ore-bearing structure of the deposit are the checkerboard-type structure of the tectonic framework, the NE-trending faults (inclined NW) and NWW fault-trending, and the interlayer fault zones in the lower plate of NWW-trending faults, respectively. In addition, there are NW trending (NNE trending) ore-breaking structures in the mining area, which obviously cut and shift the ore bodies and control the spatial positioning of the ore bodies. On the basis of summarizing the structural ore-controlling regularity, the ore-forming tectonic system of the deposit is established, which lays a foundation for ore prospecting and genetic study of the deposit. |
