摘要: 为了明确大脑坡矿区沉积和断裂构造特征，以及沉积和断裂构造对铅锌成矿控制作用，笔者从大脑坡矿区沉积-断裂构造特征出发，识别了大脑坡矿区生物礁沉积，并进一步将大脑坡矿区主要断裂系统划分为3个断裂带，即花垣-张家界断裂带（F1为主断层）、阿碧林场-清水塘断裂带（F2为主断层）、开支铺-凉水井断裂带（F3为主断层）。通过分析断裂活动期次与成矿关系，将断裂系统划分为3个类型，即区域继承性断裂、成矿期断裂及成矿后断裂。其中，区域继承性断裂以花垣-张家界断裂为主；成矿期断裂主要为阿碧林场-清水塘断裂带的F2、F108及F2-1断裂；成矿后断裂受成矿后构造应力复杂多变的影响，分布和展布形态较为复杂，全区均有发育。结合大脑坡矿区清虚洞组沉积环境、断裂构造与成矿相互关系分析，认为大脑坡矿区主要成矿模式为深部矿液通过区域继承性断裂及成矿期断裂向上迁移，经过藻灰岩层时，有利的容矿空间使成矿流体发生交代和沉淀作用，富集成矿。同时进一步总结了大脑坡矿区铅锌矿成矿规律，认为区域性继承性大断裂（花垣-张家界断裂带）控制着整个矿田的延伸分布特征，藻礁相与成矿期断裂的复合部位是良好的矿床定位空间，控制着富矿体的大小及规模；成矿期断裂构造带上进一步密集发育节理和次级断裂的部位往往也是矿体产出的集中区域。Abstract: In order to clarify the tectonic features of deposition and faults in Danaopo mining area and the controlling effect on the Pb-Zn mineralization, this paper identified the reef deposits of this area and divided the main fault systems into three fault systems:Huayuan-Zhangjiajie fault zone (F1 main fault), Abilinchang-Qingshuitang fault zone (F2 main fault) and Kaizhipu-Liangshuijing fault zone (F3 main fault) Layer). The fault systems are further divided into three types based on the relationship between the stages of fault activity and mineralization:regional inherited fault, metallogenic fault and post metallogenic fault.The regional inherited fault is mainly Huayuan-Zhangjiajie fault; the fault in the metallogenic period is mainly F2, F108 and F2-1 faults in Abilinchang-Qingshuitang. The distribution of the post metallogenic fault, which develops in the whole area, is more complicated because of the post metallogenic tectonic stress. Based on the relationship between the sedimentary environment, the fracture structure and the mineralization of Qingxudong Formation in Danaopo mining area, it is considered that the main metallogenic model is that when the deep ore fluid moves upward in the metallogenic period by the algal limestone through the regional inherited faults,the metallogenic fluid in the ideal space undergoes metasomatism and deposition, forming the mineralization. The authors thus summarize the metallogenic law of lead-zinc deposits in Danaopo mining area and believe that the regional inherited large fault (Huayuan-Zhangjiajie fault zone) controls the extension and distribution of the whole ore field. The joints and the secondary faults in the metallogenic period is the concentrating area of high-grade ore body.
