摘　　要：对会泽铅锌矿成矿构造体系、构造控矿型式进行研究 ,认为小江深断裂带和曲靖—昭通隐伏断裂带为矿床形成提供了有利的构造背景 ,矿床严格受北东向压扭性断裂控制 ,“阶梯状”和“多字型”构造是矿区具有普遍性的控矿构造型式 ,北东构造带是主要的成矿构造体系 ,提出麒麟厂矿床主矿体向南西向侧伏 ,通过工程验证新增铅锌矿金属储量近 1 0 0万t。Based on a great deal of macroscopic and microscopic geological research, the ore\|controlling tectonics, major metallogenic tectonic systems, types of ore\|controlling structures and model of ore\|forming tectonics have been put forward and summarized. It is thought that the Xiaojiang deep fault zone and the Qujing\|Zhaotong concealed fault zone have provided favorable tectonic backgrounds for the formation of ore fluids and deposits, which are controlled strictly by the NE extending faults. Structural types (ladder\|type and Duozi\|type) are widespread ore\|controlling structural types in the mining area, and the NE structural zone is a major ore\|forming structural system. Especially, the major orebodies of the Qilinchang deposit which plunged in the SW direction have been brought forward. Then it is pointed out the prognosis directions at the depth. The tectono\|geochemical method has been applied, and prognosis orientation of concealed ores has been broken through in the Qilinchang mining district, and ore\|search targets are along the Nos. 44-62 exploration lines. The reserves of lead and zinc metals have been expanded to about 1,000,000 tons, and a great break through has been made in prognosis of concealed ores.
