| Abstract: | Using the combined method of fractional Brownian motion and geostatistics extracting the concealed fractal information from the geochemical data, an accurate model to predict the regional background and local background with the improved direction-fractal estimating method is established, and finally the geochemical anomalies are delineated. Although the studied data here are the gold content in the stream sediments, the model and method proposed are also appropriate for the study of other geochemical elements. |
