摘要
本文根据主干断裂在平面上的展布特征和剖面上的组合形式，阐述了主干断裂与成矿的关系，即：不同级别的断裂构造，分别控制了矿田、矿床和矿体的空间展布，区域的断裂拐弯构造控制了矿田；局部的断裂拐弯构造控制了矿床；不同型式的构造组合控制了矿体。断裂构造的物质成分简单与否，对成矿起着绝对重要的作用，当断裂构造的物质成分复杂时，对成矿有利，反之则不利。
Based on the distribution characteristics of major fault on the plan and assemblage form of major and subsidiary faults on the section,this paper expounds the relationship between major fault and uranium ore-formation,namely:different orders of fault structure control the spatial distribution of ore fields, ore deposits and ore bodies respectively, regional turning sites of the major fault control the ore fields;local turning sites of the major fault control ore deposits; different types of structural assembleges control ore bodies. Whether the matter compositions of fault structure are simple or not,it plays an absolutely important role in oreformation. The complicated matter compositions of fault structures are favourable for oreformation, conversely,simple compositions are unfavourable.
