Most of the geological researchers working in the northwestern Hunan believe that the Zhang (Jiajie)-Hua (Yuan) fault zone, the Lianghe fault zone and the Malichang fault zone have played an important role in controlling the mineralization of the Huayuan lead-zinc ore field. This article collects a large amount of geological and mineral exploration results, using the extensional structure theory to systematically discuss the influence of the three large fault structures developed in the Huayuan ore field and the four faulted block structures on the lead-zinc mineralization in the ore field. The author believes that the extensional structure of the Huayuan Ore field shows the complete appearance of normal faults, the fractured zone that the extension of ductile rocks in the deep crust thrusts to the surface and the fault block structure with complete rock formation are the prominent features of the extension structure of Huayuan ore field. The formation of lead-zinc deposits is the result of the joint action of the extensional fault zone and the fault block structure generated by its cutting. %K 湘西北地区,花垣铅锌矿田,伸展构造特征,成矿影响
