Geochemical and Geophysical Data Processing Aided by "Multifractal-Spectrum" Filters for GIS-Based Mineral Exploration

A recently developed method, on the bases of "multifractal spectrum" filters for mineral exploration, is introduced in this paper. The "multifractal spectrum" filters, a group of irregularly shaped filters that are constructed on each processed datum, can be used to separate various types of geochemical and geophysical anomalies. The basic model, with an emphasis on the GIS based implementation and the application to the geochemical and geophysical data processing for mineral exploration in southern Nova Scotia, Canada, indicates its advantage in the separation of multiple anomalies from the background.
