Application of singularity analysis for mineral potential identification using geochemical data — A case study: Nanling W–Sn–Mo polymetallic metallogenic belt, South China

摘要: Abstract The Nanling W–Sn–Mo polymetallic belt located in southern China is endowed with considerable mineral resources, especially deposits. Most of these deposits were formed within a short time interval at the age Yanshanian. In this paper, singularity analysis context multifractal was used to identify weak anomalies hidden geochemical background. C-A method applied determination threshold values three elements (W, Sn and Mo) using derived indices. Using values, each maps classified into levels based on indices, then integrated by raster-value overlay method. resultant prospectivity map generated not only highlights known areas mineralization, but also identifies high potential no occurrences.
