| Abstract:The ore-search technology based on multi-spectrum remote sensing data has been successively applied to the Gobi arid region, whereas
there are relatively few data for the usage of this technique in low-mountain and hill areas. This paper takes the Abagong lead-zinc deposit in Altay, Xin鄄
jiang as the study area for this issue, where the landform is characterized by low mountains and hills. We study the main altered mineral assemblages in
the Abagogn lead-zinc deposit and ltheir reflectance spectra, and the absorptive properties of each band in the multiple spectra. Using the ASTER remote
sensing data, we extract the structural, lithological and alteration information of the deposit, which are well consistent with the geological data. We make
integrated analysis of information from geology, geochemical exploration and remote sensing on the GIS platform. The geochemical anomalies exhibit the
character of “surface冶and the alteration anomalies have the character of “point冶. In the all, the anomaly range determined by remote sensing is smaller
than that from aerial- magnetic and geochemical information, so the remote sensing can be used to reduce the scope of exploration rapidly and accurately |
