In Geoscience data processing, removing the interference of the original data, and keeping real information is an urgent problem to solve. This article introduces the fast Fourier transform to processing geoscience data, through the analysis of the spectral density figure in geochemical exploration data, in order to optimize data, and improve the accuracy of anomalies delineated. This paper takes hubei green mountain copper-ore in the study area 1:200000 stream sediment survey data to analyze the data processing, the superiority of the proposed method is verified.
