Prominent effects of multispectrum remote sensing data in prospecting deposits have been achieved in Gobi Arid Zone, whereas there is lesser information of remote sensing in lowhill land form of Altay region. In this paper, Abagong iron deposits zone in Altay, Xinjiang, which land form is lowhill, is the study area. Study the main altered mineral assemblages in Abagong iron deposits and list their reflectance spectra. The special bands of absorptive vale of reflectance spectra have been obtained from ASTER data. The absorptive vales of altered minerals are the principle and basis for remote sensing information extraction. Structure and lithology information are extracted form ASTER remote sensing data, and the results are well consistence with the filed geological survey. Alteration anomalies information is extracted from ASTER data, extraction of alteration anomalies information is well consistence with the geology data. Synthetic analyses of remote sensing, geology data, aeromagnetic anomaly, geochemical anomaly are studied on the GIS platform. The remote sensing and the aerialmagnetic information are similar on trends and their spatial distributions.
