Fractal Gradient Method to Determine the Geochemistry Anomaly Concentration Zoning

Geochemistry anomaly concentration zoning is an important index in anomaly evaluation of Geochemical prospecting. In traditional methods, the main parameters are often assigned by human and lack of theoretical basis. Geochemical field has fractal feature and gradient feature of its mineral element content, so this paper established fractal gradient indicator. We argues that the Geochemistry anomaly concentration zoning reflect the geological boundaries of mutations in the element content. Element content with a rapid change near the boundary will result anomaly of fractal gradient in the geochemical field. This paper divides the boundary of concentration zoning by the fractal gradient method. Finally, we verified the method by application examples. The results show that the fractal gradient method can distinguish concentration zoning boundaries, and can more accurately show anomaly morphology Attitude. The algorithm to control the concentration of sub-boundaries is more in line with the actual geological conditions, its result is better.
