Abstract：In view of the problem of remote sensing anomaly information extraction,the method of independent component analysis is introduced.Taking Qinghai Dulan County copper and polymetallic deposits as example,remote sensing anomaly information of the study area was extracted through independent component analysis,compared those result with principal component analysis,and according to the relevant geological background and on field verification,the results show that independent component analysis is better than the principal component analysis.The independent component analysis method has good prospects in terms of the extraction of remote sensing anomalies,and has some promotional value in the field of geological prospecting.
