| 摘 要： | 本文在深入分析巴什布拉克铀矿区油气还原蚀变岩石的光谱特征,ASTER与ETM数据对蚀变岩石光谱特征反映的差异性的基础上,提出了正反两种蚀变信息提取的思路和两种数据在不同思路下提取蚀变信息的效果对比。研究表明,利用ASTER数据与ETM数据在增强研究区三价铁信息,间接反映油气还原蚀变规律方面效果相当;而在直接增强油气还原蚀变信息方面,ASTER数据的应用效果明显好于ETM数据。增强的遥感油气还原蚀变信息对分析研究区白垩系油气还原蚀变规律和矿区外围铀矿找矿具有重要的意义。

| Abstract: | Based on analyzing the spectral characteristics of the reduced alteration sandstone of gas and oil in Bashibulake uranium ore district,and the difference in illustrating the spectral feature between ASTER and ETM+ data,two kinds of technologic ideas were proposed to study the remote sensing reduced alteration information directly and indirectly.Following the two ideas,different effects in using ASTER and ETM data were compared respectively.Studies showed that both ASTER and ETM had equal and good effect in ... |
