- Abstract
- It is difficult to extract the clay alteration information in the vegetation coverage, and the extraction precision of alteration minerals is low all the time because of the smaller altered targets and the smaller scale image. Nevertheless, there is a good relationship between the clay alteration and the uranium mineralization. In order to get the good extraction effect in the vegetation coverage, the paper chose the uranium metallogenic zone of Tao Shan in south of China as the study area, used the ASTER image as the data source and devised a technological method to extract the clay alteration information in the vegetation coverage. What’s more, the paper developed a new method named RBD-PPI to acquire the spectrum of end-member. According to the experiment of this paper, the result of alteration information extraction achieved the good consistence with the known uranium deposits, and the important clay alteration abnormal have been validated in the field. Based on the information extraction result, the paper proposed some potential area for the uranium exploration. Above all, the result reveals that the method developed in the paper gets the satisfying result, furthermore, the technological method could provide good reference for the clay alteration information extraction in other area with high vegetation cover.
