基于Landsat TM的个旧锡矿成矿信息提取与找矿预测

Extraction of Metallogenic Information and Prospecting Prediction Based on Landsat TM in Gejiu Tin Deposit Area

在对云南个旧锡矿矿区成矿地质环境、地质特征和成矿规律研究的基础上,以Landsat TM多光谱影像数据为基础信息源,利用遥感找矿技术对个旧锡矿地质构造信息和蚀变异常信息进行提取。在此基础上,综合利用已有的地质、物探和化探成果,结合野外实地调查后圈定了3类共9个找矿远景区。

On the basis of studying mineralized geologic environment, geologic feature and metallogenic regularity of the Gejiu Tin deposit located in Yunnan province, and Landsat TM muhispectral image data used as basic information source, the remote sensing prospecting is adopted to extract geologic structure information and alteration anomaly information of Gejiu deposit. Then,with comprehensive use of the achievements in geological, geophysical and geochemical exploration, and combining with the field survey, three kinds of （9 in total） ore-prospecting areas are delineated.
