| 摘 要： | 在分析宁夏省中卫地区铀成矿要素的基础上,提出了结合研究区成矿要素的ETM遥感蚀变提取改进技术,对非铀成矿有利地层进行了掩膜处理,减少了非相关地层中岩石矿物对信息提取的影响,野外查证后认为采用改进后的方法可使蚀变信息提取的精度更高,并在中卫地区发现了多条铀矿异常线索。

| Abstract: | Based on the analysis of uranium mineralization essential factors in Zhongwei area of Ningxia,this paper put forward an improved method of alteration extraction from ETM data with mineralization essential factors.The noise impact on alteration extraction was reduced by masking the range of non tar get strata of uranium mineralization.It's proved through field verification that the method can improve the alteration extracting accuracy,and several anomaly uranium were found in Zhongwei area with the clue of alteration mineral extracted by improved remote sensing method. |
