摘要
在内蒙古阿鲁科尔沁旗地区地质调查工作中,应用"去干扰-主分量分析-异常筛选"方法体系,根据研究区成矿条件和Landsat8卫星OLI传感器数据特点,进行遥感蚀变异常提取.在对提取结果进行野外验证时,发现多处矿化点,有力支持了地质找矿工作.
The methodology of"interference suppression-principal component analysis-exception filter"is applied in the geological survey in Ar Horqin Q i,Inner Mongolia.The alteration anomaly information is extracted by remote sensing on the basis of metallogenic condition in the study area and characteristics of Landsat 8 OLI sensor data.Quite a few mineralized occurrences are also discovered in the field validation for the extracted result,which provides strong support for geological prospecting.
