摘要
利用多光谱遥感技术进行蚀变矿物(绢云母、高岭土、绿泥石、赤铁矿、褐铁矿等)信息提取已广泛应用于矿产资源勘查工作中,文章基于Landsat 8 OLI数据采用主成分分析法和主分量门限法对铁染异常和泥化异常进行提取并分级处理,取得了较好成果,为本区成矿预测及下一步找矿工作提供了依据。
The information extraction of alteration minerals(sericite,kaoline,chlorite,hematite,limonite,etc.)by multi-spectral remote sensing technology has been widely used in mineral exploration.With Landsat 8 OLI data,the principal component analysis and threshold techniques are used to extract and classify iron oxides and hydroxyl-bearing anomalies.Good results have been achieved,which provided a basis for the metallogenic prediction and the next exploration in the working area.
