English abstract:
Mineral exploration in biogeochemistry is related to the detection of anomalies in soil,which is driven by many factors and thus a complex problem. Mikˇsov´a, Rieser, and Filzmoser (2019b) have introduced a method for the identification of spatial patterns with
increased element concentrations in samples along a linear sampling transect. This procedure is based on fitting Generalized Additive Models (GAMs) to the concentration data,and computing a curvature measure from the pairwise log-ratios of these fits. The higher
the curvature, the more likely one or both elements of the pair indicate local mineralization. This method is applied on two geochemical data sets which have been collected specifically for the purpose of mineral exploration. The aim is to test the technique for its ability to identify pathfinder elements to detect mineralized zones, and to verify whether the method can indicate which sampling material is best suited for this purpose.
