Title: Application of enhanced multi-element geochemical signatures, primary and secondary geochemical haloes for vectoring into mineralized zones and delimiting exploration targets: A case study from the Serenu deposit, SE Iran

Abstract

The main application of multi-element geochemical data, primary and secondary geochemical haloes is to delimit the exploration targets as vectoring to mineralized ore bodies in porphyry deposits. A GIS-based expected value function and fuzzy operators was applied to integrate the different geochemical layers into a single model for delimiting and generating exploration targets. In addition, the primary and secondary geochemical haloes was correlated for recognition favorable areas. The comparison of fuzzy operators and expected value function with combined primary and secondary geochemical haloes demonstrated that the integrated fuzzy and GIS-based values functions are more efficient for generating a stronger geochemical evidence layer. It can be concluded that the simultaneous utilization of all input variables by the integrated fuzzy operators and expected value function is the main reason for the efficiency of those algorithms relative to single correlative geochemical haloes. These techniques was assessed by using a stream-sediment and lithogeochemical data set for prospecting porphyry Cu-Mo deposits in the Serenu deposit, southeastern Iran.
