搭载于美国航空航天局(NASA)Tera卫星上的ASTER传感器具有从太空测量来自地球表面的多光谱热红外(TIR)辐射的能力.基于地球表面典型岩石类型的热红外光谱特征分析,我们建立了几种探测硅质岩、碳酸岩及硅酸盐岩中全岩SiO2含量的指数.我们将这些指数应用于帕米尔东北缘地区的ASTER多光谱热红外图像数据,并将遥感解译分析结果与该区已发表的地质资料和野外调查结果进行比较.结果表明ASTER热红外遥感方法具有很大的应用潜力:它可以有效地提供整个帕米尔地区的主要地质信息.这是常规的地质调查方法无法完成的,因为该区的野外地质调查受到自然地理条件等因豢的限制.

ASTER sensor aboard NASA's Terra satellite has the capability of measuring multispectralthermal infrared (TIR) emission from the earth's surface to space. Utilizing the TIR spectral properties ofthe rock types typical on earth, several indices for detecting siliceous and carbonate rocks, and anotherindex correlating to the bulk SiO2 content in silicate rocks with ASTER-TIR data are proposed. They areapplied to the ASTER-TIR data scenes observing a study area selected in the northeastern Pamirs, and theresults are compared with the published geological information and the data obtained at the fieldgeological survey conducted at the study area. It shows a potential usefulness of this approach inproviding preliminary geological information all over the Pamirs where is difficult to access bygeographical and political reasons.
