| 摘 要： | 以黔东北锰矿矿集区为例，通过分析含锰岩层、矿床和矿体特征，确定以伴生的黄铁矿、绿泥石和次生的锰氧化物作为锰矿化遥感信息提取的间接标志；在此基础上，采用基于主成分分析、支持向量机和蚁群算法的组合式数据挖掘方法，提取了研究区ASTER遥感图像的锰矿化信息，进而圈定了遥感光谱异常区。经与已探明的矿床对比，在空间分布上有较好的一致性。研究结果表明，提出的基于伴生和次生矿物遥感数据的组合式挖掘隐伏方法体系，圈定"大塘坡式"锰矿成矿有利区，具有可行性和实践意义。

Extraction of hidden manganese ore information with combined mining of associated and secondary mineral of remote sensing data in northeast Guizhou |
| |
| Abstract: | The northeast Guizhou manganese ore area is taken as a study area in the paper. The associated pyrite, chlorite and the secondary manganese oxide were as extraction marks of manganese ore by analyzing the characteristics of the manganese-bearing strata, the ore deposits and the ore bodies. Furthermore, the manganese mineralization information of ASTER image is extracted by using the combined data mining method based on principal component analysis, support vector machine and ant colony algorithm, and then the abnormal region of remote sensing image is delineated. Compared with the abnormal region and the proved deposits, there is a better consistency in spatial distribution. The results show that the combined mining method system for hidden manganese ore based on the remote sensing data of associated and secondary minerals proposed in this paper is feasible and practical for delineating the favorable metallogenic area of "Datangpo type" manganese ore. |
