A comparative study of trend surface analysis and spectrum-area multifractal model to identify geochemical anomalies
2015, Journal of Geochemical ExplorationCitation Excerpt :However, the anomaly distribution obtained by the S–A model was concentrated in the study area, which reduced the effects of geochemical noise by band-pass filter. Some issues with the TSA need to be further addressed such as the selection of the surface that best fits or explains the data, or whether any of the complex trend models can be supported by an appropriate geographic theory (Oliveira, 1979; Unwin, 2009). As a global method, the result of TSA is influenced by grid resolution, the number of samples and the outliers in the data.
