| 摘 要： | 文章主要对北祁连中段北坡铀矿床（点）的地质特征、成因类型和成矿地质条件进行了分析,根据成矿特点将成矿类型划为四类,其中碱交代热液型最重要。通过对控矿因素的研究,认识到矿化带被深断裂和大的褶皱所控制,铀矿化与岩浆晚期热液活动有关,矿床的成矿物质部分来源于地层。矿化的形成是地层、构造和岩浆活动联合作用的结果。指出了矿带内成矿预测远景区,并对部分远景区进行了评价。

| Abstract: | An analysis was made on geological characteristics,genesis type and ore forming condition of uranium deposits（spots） on northern slope in the middle section of northern Qilian Mountain.The ore forming types were classified according to metallogenic features with alkali alteration hydrothermal type as most important one.Based on the study on ore controlling factors,it is recognized that the ore belt was controlled by deep rooted fractures and large fold and uranium mineralization was associated with the hydrothermal activities of magma in late period.Part of the ore matter originated from strata.The formation of mineralization was the result of joint action of stratum,structure and magma process.The ore forecasting perspective areas within the ore belt was pointed out and an assessment was made for part of the perspective areas. |
