Abstract：Based on an analysis of mineral composition and spectral characteristics of samples collected in Bulunkou area of West Kunlun Mountains,the authors extracted the end-member spectra of lithologic units by using ASTER data of the study area,and the ASTER VNIR and SWIR data of the study area were processed by matched filtering method, and then nine important litholigic units in the study area were extracted. These lithologic units include biotite quartzite,biotite plagioclase gneiss,biotite quartz schist and biotite hornblende plagioclase gneiss which belong to Palaeoproterozoic Bulunkuole Group (Pt1) and chlorite sericite slate,black phyllite and sericite quartz schist that belong to Silurian Wenquangou Group (SW) as well as quartz diorite and tonalite. An analysis of geological data available and field survey results demonstrate that the method adopted by the authors can extract credible information and supply references to lithologic mapping and mineral exploration.
