遥感地质扩矿的关键是在成矿理论的指导下根据遥感影像特征提取和识别与成矿、控矿有关的地质信息。将区域成矿地质背景分析与遥感应刚研究相结合,充分发挥遥感技术的优势,针对该区实际情况和覆盖区的特点,通过对多种卫星遥感影像数据进行不同的变换处理,提取了覆盖区地质体的信息。根据透视信息、地貌特征、水系结构、色调差异等解译分析了区域地质背景和主要控矿因素;根据遥感影像特征识别了主要的产铀火山构造盆地、控矿构造、中生代火山岩系、火山机构、成矿岩体等,建立了不同类型矿床遥感影像模式。应用多源信息复合技术预测成矿远景区。研究表明,在大面积覆盖、地质背景复杂的地区应用遥感技术提取和识别找矿信息是可行的,认为该区具有良好的区域成矿地
The key to remote sensing geological prospecting is to extract and identify the geological information related to metallogenic and ore-controlling based on the characteristics of remote sensing images under the guidance of metallogenetic theory. According to the actual situation of the area and the characteristics of the coverage area, different satellite remote sensing image data are transformed and the coverage is extracted by combining the advantages of the remote sensing technology, District geological information. According to the perspective information, the geomorphic features, the structure of the water system, the differences in hue and other interpretations, the regional geological backgrounds and the main ore-controlling factors are analyzed. Based on the features of the remote sensing images, the major uranium volcanic tectonic basins, ore-controlling structures, Mesozoic volcanic rocks, , Metallogenic rock bodies and so on, the remote sensing image modes of different types of ore deposits have been established. Prediction of metallogenic prospect by multi - source information composite technique. The research shows that it is feasible to use remote sensing technology to extract and identify ore-prospecting information in a large area with complex geological background. It is considered that this area has good regional metallogenic
