摘　　要：天合兴—王家店金-多金属矿带中,已发现近10处小型金、银、铜、铅、锌矿床。该地区经历了多次剧烈的构造—岩浆事件,多期的构造、岩浆活动为本地区金-多金属矿的富集成矿创造了有利条件。经研究认为南北向断裂是天合兴—王家店金-多金属矿带的导矿构造,北东向和北西向共轭剪切断裂是容矿构造,北东向断裂在空间上具等距分布的特点,同时常伴随有辉绿岩、花岗闪长岩、正长斑岩等脉岩侵入。这些规律的发现在本区提高了地表工程的有效性,缩短了勘查周期,对找矿勘查具有重要的指导意义。In the gold-polymetal ore belt in Tianhexing-Wangjiadian district, about 10 gold, silver, copper, lead or zinc deposits had been found. The district experienced many times intensively tectonics-magma activities. And these activities created advantages for mineral liquid enrichment. The SN fractures was considered as the introductory structure of ore-forming, while the NE and NW conjugate cut fractures were the host structures. The NE fracture has characteristics of equidistant distribution in the space. Meanwhile, there are dikes （include diabase, granodiorite and orthophyre dike） invaded along the fracture. The discovery of the regularity is of great instructive meaning for prospecting.
