摘　　要：国内外相当多矿床产出的构造位置,特别是富矿体的产出位置处在不同走向,或不同性质与类型,或不同规模序次的构造交会部位。根据不同走向构造的规模大小、性质、序次及活动的先后顺序及其与岩浆活动的紧密程度,可划分不同类型、不同大小的矿床。分析国内外不同构造交会部位的成矿实例,结合多年来的找矿实践,认为构造交会部位是成矿,甚至成富矿的有利部位。A considerable amount of orebodies,especially rich ores at home and abroad,were discovered at the tectonic intersections of different strikes,features,types,scales or phases. The scales,features,phases and active sequence of the structures,as well as their close relationships with the magmatic activities defined the type and the size of the orebodies. With several cases located at these intersections and the authors＇ years of prospecting practice,this paper points out that orebodies,especially rich orebodies tend to form at the intersections,which would provide reference for geological prospecting.
