Application of remote sensing technique to metallogenetic prognosis in the covered area

摘要

The idea, method, and procedure of remote sensing research in the covered area are discussed. Using satellite image processing method (including faint information processing) in combination with multiple information comprehensive interpretation to decipher information of geological bodies covered with unconsolidated overburden and to predict favourable districts is also introduced. Using the Yili basin as an example, interpretation of ore-controlling factors is described. The concealed productive uranium formations which dominate uranium distribution have been delineated. The uplift and subsidence which are related to sedimentary environment and mineralization concentration have been discriminated. The faults (including the buried faults) which control the formation and development of the basin have been discerned. The stable and active areas, which are connected with uranium concentration and preservation, and regional discharge zone have been interpreted. The result shows the feasibility of using remote sensing technique to predict the mineralization in the covered area, and six target areas have been optimized for further uranium reconnaissance and exploration in the study area.
