摘要
运用遥感技术,以ETM+为主要数据源,在辽东吉南地区建立起地层单元、岩浆岩和断裂构造的解译标志,完成区内遥感蚀变信息的提取工作;详细探讨了区内主要金属矿床的遥感地质模型。根据区内典型矿床成矿地质条件、遥感解译标志等建立遥感矿化模型。结合提取的全区遥感矿化信息进行成矿预测,全区共筛选出Ⅰ级成矿预测区24处,Ⅱ级预测区86处,Ⅲ级预测区12处。
With remote sensing technique, choosing ETM imageries as main data source, we built interpretation keys of stratigraphic unit, magmatic rocks and fault structure, then extracted the interpretation alteration data of the studied area and detailedly studied remote sensing geological model of main metal ore deposit in the work area. According to the geological condition and remote sensing interpretation keys of some typical ore deposits, we built remote sensing mineralization models and carried out metallogenic prediction with the extracted remote sensing mineral data. There were 24 level Ⅰ , 86 level Ⅱ and 12 levelⅢ pieces of mineralization prospected areas.
