Analysis of remote sensing prospecting potential of the type of Duolong porphyry copper deposits in the north of Bierezecuo in Tibet

Basing on the ETM⁺ multi-spectrum data,the north of Bierezecuo in Tibet was got aanalysis of remote sensing prospecting potential.Firstly,the author interpreted geological characteristics and extracted alteration information.Afterthat,extracted the remote sensing prospecting elements in study areas,through the porphyry copper deposits metallogenic regularities and remote sensing mineral resources geology characteristics.Finally,8 ore-hunting prospect ares were delineated.
