| 摘 要： | 利用ENVI软件,对青海东昆仑东大滩地区Hyperion高光谱数据进行处理后,运用光谱角填图法、波谱特征拟合法及匹配滤波法,对高光谱数据进行了矿物蚀变信息的提取,获得了东大滩地区矿物蚀变图像。在磨石沟二长花岗岩、花岗闪长岩岩体外围的南东侧,存在着硅酸盐、碳酸盐、三价铁等矿物蚀变。野外对蚀变异常地段进行验证,野外观察的矿物蚀变异常与遥感图像显示的蚀变异常区域基本吻合;结合区域地质背景与成矿条件,进行了区内成矿预测与优选靶区圈定,并发现了东大滩铜矿化点,说明高光谱遥感能为找矿提供准确且可靠的信息。 |
| 关 键 词： | Hyperion 高光谱遥感 矿物蚀变 铜矿化 东大滩 东昆仑 |

| Abstract: | Taking Dongdatan district in Qinghai Province as an example,the characteristics and the processing techniques of the Hyperion data are discussed in detail.With methods of SAM,SFF and MF,the hyperspectral data of Hyperion were processed,and the mineral alteration image of Dongdatan district was acquired through the extraction of mineral alteration information from the hyperspectral data using ENVI.The image shows that the mineral alteration assemblages of silicate,carbonate and ferric iron exist at the south... |
