This is the first paper in the serial articles on the new parameter for the prediction of the mineral resources-alteration RS anomalies. The geological basis and the spectral presupposition for the alteration anomalies are discussed. The result of extracting alteration anomalies in an area of more than 20 000 square kilometers within East Tianshan Mountains and the result of the in-situ investigation of some anomalies are reported. Among the 71 known deposits or mineralization spots in this area, 61 have the corresponding alteration anomalies. The coincidence coefficient is as high as 85.9%. Some new related terms are defined.
