| 中文摘要: |
| 通过对东天山玉带地区航空高光谱遥感数据预处理、地面光谱数据处理、矿化蚀变分带和蚀变矿物组合特征分析、典型蚀变矿物诊断性波谱特征精细研究、影像光谱与实测光谱对比分析等,提取了绿帘石、铁氧化物、方解石、黄钾铁矾、蒙脱石、高岭石、绢云母、硫酸盐、明矾石和叶蜡石等10种蚀变矿物分布信息。结合野外地质调查成果,发现绿帘石丰度的发育和分布是一种较好的找矿标志,对找矿有指示意义。 |

| Research work presented in this paper is conducted hrough preprocessing of aerial hyperspectral remote sensing data, processing of ground spectrum data, analyzing characteristic of mineralized alteration zones and the combination of altered minerals, studying of diagnostic characteristics of typical altered minerals and the comparing with image spectrum and the measured spectrum in Yudai of the east Tianshan. Distribution information of 10 alteration minerals, such as epidote, iron oxide, calcite, jarosite, montmorillonite, kaolinite, sericite, sulfate, alunite and pyrophyllite is etracted out,extracte the of Combined with results of field geological survey, it is found that the development and distribution of epidote abundance is a good prospecting indicator, which is of great significance for prospecting. |
