This article analyzes the mineralization mechanism of the uranium ore , constructs a series of spectra indexes including the ferric oxide index , the ferrous oxide index , the oxidation index , clay mineral index , brightness index , the green index and the humidity index , and draws the distribution and scope of the oxidation belt , deoxidation belt , the supplies and partial drainage of ground water in the research area , thus selects the advantageous area of uranium mineralization 通過分析鈾礦的成礦機理,構建了氧化鐵指數(shù)、氧化亞鐵指數(shù)、氧化指數(shù)、粘土礦物指數(shù)、亮度指數(shù)、綠度指數(shù)和濕度指數(shù)等一系列光譜指數(shù),提取了研究區(qū)氧化帶、還原帶、地下水補給與局部排泄的分布和范圍,從而圈定了鈾礦成礦的有利區(qū)。
