【摘要】：以新疆白楊河鈾鈹?shù)V區(qū)為研究區(qū),通過建立航空高光譜數(shù)據(jù)CASI/SASI礦物填圖處理流程,運用混合調(diào)制匹配濾波技術(shù)實現(xiàn)了多種蝕變礦物的填圖。填圖結(jié)果的野外驗證表明,3種絹云母亞類的準(zhǔn)確性高于85%,其他各類礦物的準(zhǔn)確性高于90%。疊加研究區(qū)鈾礦點資料,發(fā)現(xiàn)白楊河礦區(qū)赤鐵礦化和高鋁絹云母的空間分布特征與鈾礦點分布高度相關(guān),主要位于楊莊巖體與外圍火山巖的北接觸帶附近,呈明顯分帶性。并且,高、中、低鋁絹云母的空間分布指示礦床北部和南部的熱液活動溫度可能存在差異,區(qū)域上存在多期熱液活動作用。這為礦區(qū)外圍找礦預(yù)測和區(qū)域地質(zhì)成因研究提供了參考和依據(jù)。
[Abstract]:Taking Baiyanghe uranium beryllium mining area in Xinjiang as the study area, by establishing the CASI / SASI mineral mapping process of aviation hyperspectral data, the mixed modulation matched filtering technique is used to map many altered minerals. Field verification of the mapping results showed that the accuracy of the three sericite subclasses was higher than that of the other minerals, and the accuracy of the other minerals was higher than that of the other minerals. It is found that the spatial distribution characteristics of hematitization and high alumina sericite in Baiyanhe ore area are highly related to the distribution of uranium ore points, mainly located near the northern contact zone between the Yangzhuang rock mass and the surrounding volcanic rocks, which shows obvious zonation. Moreover, the spatial distribution of high, middle and low aluminum sericite indicates that there may be differences in hydrothermal activity temperatures between the northern and southern parts of the deposit, and there are multiple hydrothermal activities in the region. This provides a reference and basis for the prediction of ore prospecting in the periphery of the mining area and the study of the regional geological origin.
