Abstract Abundant salt lake ore deposits are developed in vast rural areas of Tibet, but with very insufficient investigation. It is very difficult to conduct the exploration work by the traditional geological surveying methods in that they are very expensive and time-consuming. The remote sensing information extraction of modern salt lake ore deposits in Tibet based on TM(ETM+) data, color synthesis, density segmentation and ratio transformation has turned out to be effective. A number of perspective areas proposed on such a basis proved to be reliable, and several halide ore fields were found through verification. The remote sensing information extraction is indeed an ideal method for rapid appraisal of salt lake ore deposits in high-altitude regions of western China.
