Gold prospectivity mapping using training set of spatially similar gold deposit occurrences
Spatial data analysis is the process of seeking out patterns and association on maps that help to
characterize,understand and predict spatial phenomena (Bonham-Carter,1994).The occurrence of mineral deposit is not random,their occurrence are linked to favourable geological features.The spatial associations of geologic features and mineral occurrence have to be quantified before data integration.The quantified spatial association illustrates the behavior of each geologic feature with the mineral occurrences.The spatial association between mineral deposit occurrences and geological features such as faults may serve as important geological indicators of mineralization.In this study,26 gold deposit occurrences found to have similar geochemical-geological attributes were used as training data in the spatial association analysis and in the subsequent mineral prospectivity mapping.The other five gold deposit occurrences were used for predictive model validation.
