Efficiency of singularity and PCA mapping of mineralization-related geochemical anomalies: a comparative study using BLEG and <180μm stream sediment geochemical data

In gold (Au) exploration, the analysis of both bulk leach extractable (BLEG) and acid-extractable Au in <180μm stream sediment fraction are two most common approaches. The Eskişehir- Sivrihisar region Western Türkiye hosts several orogenic type mineral deposits. purpose this study is to delineate geochemical anomalies ore-related elements track their dispersion, which may lead discovery unknown ore This research also compares capability conventional statistical principal component (PCA), with concentration area (CA) number-size/concentration (N-S/C) fractal methods as well singularity index method differentiate anomalous background distributions. Known mineralization interest strongly reflected BLEG patterns, have robust indices C-A N-S multifractal modeling PCA. A hundred % deposits were detected using either Ag mapping whereas factor revealed 85% efficiency. Several strong Au-Ag defined by requires further follow up for new
