摘　　要：为研究甘肃龙首山地区的构造演化与铀成矿之间的关系,系统地收集了甘肃龙首山地区相关地质资料,并在此基础上结合资料对龙首山的区域构造演化进行了分析,同时开展了矿区典型构造节理应力方向及典型矿床构造期次分析,大致查明了龙首山地区构造特征及矿床的构造期次,并探讨了构造对铀成矿的控制作用。通过构造演化与铀成矿作用关系的研究,结合相关资料,分析认为,龙首山地区矿床主要分为花岗岩、白岗岩、碱交代岩3种类型;龙首山地区主要的应力方向有NW-SE向及NE-SW向;芨岭地区构造活动划分为5期。In order to study the relationship between tectonic evolution and uranium mineralization in the Longshou Mountain area,Gansu province,this paper systematically collected the relevant geological data in the Longshou Mountain area,Gansu province.On this basis,the regional tectonic evolution of Longshou Mountain is analyzed,and the stress direction of typical structural joints and the tectonic stages of typical deposits are analyzed.The structural characteristics and the tectonic stages of the deposits in Longshou Mountain area are generally found out,and the tectonic control on uranium mineralization is discussed.Based on the study of the relationship between tectonic evolution and uranium mineralization and the related data,it is considered that the ore deposits in Longshou Mountain area can be divided into 3 types:granite,white granite and alkali metasomatic rock.The main stress directions in Longshou Mountain area are NW-SE and NE-SW,and the tectonic activity in Jiling area is divided into 5 stages.
