A method for rapid prediction of porphyry copper mineralization potential based on spectral characteristics of tourmaline, includes collecting and collating data related to magma-fluid evolution, petrography and mineralogy of a porphyry copper deposit in a working area, systematically, distinguishing magmatic tourmaline from hydrothermal tourmaline in the working area, and further distinguishing phases and generations of the hydrothermal tourmaline; collecting hydrothermal tourmaline samples of the same phase and generation; performing short-wave infrared spectroscopy measurement on the collected hydrothermal tourmaline samples; extracting spectral characteristics of the Fe—OH wavelength and Mg—OH wavelength of the tourmaline samples based on The Spectral Geologist (TSG); and when the Fe—OH wavelength is less than 2245.75 nm, and the Mg—OH wavelength is greater than 2356.57 nm in the short-wave infrared spectrum of the samples, indicating that the porphyry copper deposit in an area where the samples are located has a great metallogenic potential.
