GOLD predictivity mapping in French Guiana using an expert-guided data-driven approach based on a regional-scale GIS

Abstract

The realistic estimation of gold mining in French Guiana requires including the numerous illegal gold washing activities in predictivity mapping. The combination of a classical approach, based on the algebraic method of Knox‐Robinson and Groves, with innovative processing grid‐type geochemical and radiometric data, as well as cluster analysis technique provides a better understanding of the structure of studied mineralized areas.
