摘　　要：利用CASI/SASI航空高光谱遥感数据,对新疆红柳泉地区进行了航空高光谱遥感构造解译,修正了部分线性构造及环形构造。基于航空高光谱遥感提取的蚀变信息,结合野外实地调查验证,重点分析了研究区内祥云金矿、盘龙沟金矿与构造、蚀变之间的关系,结合已有的矿产地质特征、航空高光谱遥感地质特征,在该区圈定5处找矿预测区,预测矿种为构造蚀变岩型金矿,研究成果为相同地区的成矿预测与寻找同类型矿床提供遥感依据。Remote sensing structural interpretation of Hongliuquan area, Xinjiang is conducted with CA- SI/SASI aerial hyperspectral data. Some known linear and ring structures are revised and alteration infor- mation extracted. The analysis is concentrated on relation of Xiangyun and Panlonggou gold deposits to structure and alteration. Five prospecting targets are delineated with the aerial hyperspectral geological characteristics and field check and geological characteristics of the known gold deposits. The predicted tar- gets are potential for the altered cataclastic rock type gold deposit. The interpretation result will provide remote sensing basis for the similar areas.
