贵州威宁长坪子铅锌矿区地质特征及控矿因素浅析

贵州威宁长坪子铅锌矿区位于北西向的江子山背斜铅锌成矿带中段，矿床的形成和分布受江子山背斜构造的控制。而矿体受主干构造及其压性纵断层的下盘或层间破碎带控制，或北西与北东向断裂共同控制；矿体主要呈似层状、透镜状；矿体的产出主要受地层、构造条件共同控制。系统地研究了区内的导矿、配矿、容矿构造特征，提出了地质构造是控制矿床形成和分布的主导因素，以便为区内地质找矿理清思路，指明方向。

Analysis on Geological Characteristics and Controlling Factor of the Zhangpingzi Pb-Zn Deposit,Weining,Guizhou

The Zhangpingzi lead-zine deposit,Weining,Guizhou is at the intermediate Zone of the lead-zine ore belt in Jiangzishan anticline of Northwestern,The formation and distribution of Pb-Zn ore deposits in Northwestern are controlled By the anticline of Jiangzishan.while ore bodies are controlled by the main structural sectors and Lowerlayer crushing zone,between the upper wall and the longitudinal compression fault ,and The controlling of NW and NE faults,and its ore bodies are stratoid and lenticular in occurrence.This thesis adopt firstly systematic analysis of characteristics of ore leading, distribution, storage structures in the area, and put forward that the geological structures maybe are the primary control of the ore deposit formation and distribution, contrary to the former theory that the palaeogeograpHic condition and the strata are the main factors. It provides new thought and direction to future exploration.
