| 中文摘要:石膏和盐类矿物的实测光谱特征表明,石膏反映在ASTER图像631(ETM图像743)假彩色合成图上呈现浅天蓝色调,而石盐为弱粉红色的色调特征。文章在此基础上利用主成分分析提取了石膏与盐类矿物的信息。野外查证结果显示,本次提取的信息与实际地物对应良好,并且在野外查证中新发现了一处含钾石盐层,根据遥感信息推测喀什西南凹陷区(文中D区)为找钾的预测区。 |

| Abstract:In this paper, actual spectral curves of gypsum and halite were measured by a spectrometer. The results show that spectral characteristics of gypsum can be identified by ASTER/ETM bands, which show pale blue hue characteristics in the ASTER 631 or ETM 743 false-color composite image. Based on the above characteristics, some anomalistic information of gypsum and halite was extracted by using PCA method. In combination with field verification, it can be concluded that the extracted information in this paper is consistent with the actual strata. The field verification led to the discovery of a new potassium-bearing halite layer, which seems to be a potassiumprospecting prognostic area, as inferred by remote-sensing information. |
