摘要
Linear and circular structures of the Taxkorgan region in West Kunlun were interpreted via ETM images.The results show that tectonism in the studying area was intensive.The major linear structures include NW,NS and EW trending faults.The NW trending linear structures are widespread and cut by near EW and NS trending faults,thus,the near EW and NS trending faults are later than the NW trending faults.Mineralized alteration factors were defined by spectral characteristics of the rocks in different bands.Mineralized alteration information was quantitatively extracted by multispectral remote sensing information extraction techniques.Useful alteration anomalies and metallogenic targets were located by multi-geology information integration.According to geological data,structure interpretation results and RS anomaly areas,Aranbaotai Cu-Pb-Zn,Zankan Fe,Baldir Cu-Pb-Zn,Mingtiegai W-Cu and Xiruo Mo prospecting targets were proposed.The spatial distribution of remote sensing anomalies is consistent with the known ore deposits,which showed promising application of the method in mineral resource exploration and assessment in West Kunlun.
