应用遥感技术对山西多金属成矿的灵丘地区进行成矿预测。选取ETM+影像,在图像预处理基础上进行线性体解译,利用分形理论求出全区及分段维数。采用主成分分析法提取铁染和羟基蚀变。将研究区分成64个单元区,综合分析5个已知矿区地学信息,预测出8个成矿前景单元。
Application of Remote Sensing Technology to Metallogenic Prognosis of Lingqiu Area, Shanxi Polymetallic Mineralization. ETM + images are selected, linear body interpretation is performed on the basis of image preprocessing, and the whole region and segment dimensions are obtained by using fractal theory. Principal component analysis was used to extract iron stain and hydroxyl alteration. Divided the study into 64 unit areas, comprehensively analyzed the geochemical information of 5 known mining areas and predicted 8 metallogenic prospect units.
