Abstract Using the "mask and directed principal component analysis" approach,the authors extracted the remote sensing alternation anomalies of the Duobuza porphyry copper deposit on the basis of ASTER data. The characteristics of alteration anomalies,the correlation between alteration anomalies and surface alteration and the relationship between alteration anomalies and known ore bodies were preliminarily discussed in this paper. The results show that the alteration anomalies extracted by ASTER data are relatively satisfactory and can provide the remote sensing basis for delineation of the smallest prognostic target within the forecasting work area of the Duolong copper deposit in the mineral resource potential assessment of Tibet.
