| 摘 要： | 从巴什布拉克铀矿床油气还原蚀变岩石的光谱特征分析入手，开展了基于ETM数据的白垩系油气还原蚀变信息的反向增强和基于ASTER数据的直接增强技术研究。通过对增强的油气还原蚀变信息分布特征的分析，发现矿床所在的北西西向狭长的白垩系出露范围内，西段的油气还原蚀变强烈，中段和东段的蚀变弱，从而为矿区外围铀矿找矿提供了重要依据。

| Abstract: | Based on studying spectral characteristics of sandstone that has undergone reducing alteration of gas and oil in the Bashibulake ore district,this paper has dealt with the technologies of reverse enhancement based on ETM data and the direct enhancement based on ASTER data for extracting the reducing alteration information from Cenozoic strata,and analyzed distribution features of the alteration information.It is discovered that the sandstone in the west part of the narrowly-exposed NWW-trending Cenozoic strata has undergone strong reducing alteration of gas and oil,but the middle and east parts have experienced less alteration.The result provides some important information for uranium exploration in the periphery of the Bashibulake uranium ore district. |
