摘　　要：主要介绍了塔里木盆地北缘巴什布拉克地区的控铀构造-蚀变带遥感信息增强和提取技术、构造-蚀变带的影像特点、地质特征;讨论其成因机制及其与铀矿化的关系。通过应用遥感信息与野外地质的综合分析,提出了巴什布拉克地区铀矿床是受构造-蚀变带控制的新认识。且从另外一个角度,重新审视了该区控矿的主导因素和分布规律,对该区的进一步铀矿找矿具有启迪作用。The paper is focused on recommending geological characteristics of structure-alteration zone which is found from image interpretation in Bashibulake District, north of Tarim Basin, expounding remote sensing information enhancement and extraction technique, analyzing image feature, genetic mechanism and discussing the relationship between uranium mineralization and structure-alteration zone. A new discovery is raised through applying remote sensing information analysis and geologic analysis, that is, the uranium deposits in Bashibulake District are controlled by structure-alteration zone. The new understanding provides a new view point for reconsidering main controlling factors and uranium mineralization distribution in the area. It is helpful for further reconnaissance and exploration in the area.
