Abstract

Stream sediments are the preferred sampling method in regional geochemical exploration for Au deposits in regions displaying well-defined drainage systems. Analysis of either bulk leach extractable gold (BLEG) and aqua regia-extractable multi-element analysis of fine fraction sediments are two common analytical approaches. This study examines the efficiency of detecting known ore deposits and prospects using parametric (Q-Q) and nonparametric (U-spatial and C-A fractal) modeling of a large compilation of company stream sediment and rock chip geochemical data from exploration programs in the Eastern Black Sea region of Turkey, to identify geochemical patterns related to major precious and base metal deposits.
