| Abstract: | ASTER multispectral remote sensing data are applied to interpretation of typical magmatic lithologies in Maqindawan area at south margin of Qaidam basin. The spectral analysis method and minimum noise transformation method (MNF) were tested. With the methods typical magmatic lithologies can be successfully extracted. Referring to geological data available and field check the methods are feasible to lithological mapping and the extracted data can be applied to field lithological mapping and ore deposit prospecting. |
