Criteria for Determining the Genesis of Placers and Their Different Sources Based on the Morphological Features of Placer Gold

Based on the identified typomorphic features of placer gold, a set determined morphogenetic criteria is proposed to identify genesis gold content and different sources in platform areas, which allow more correctly selecting search methods improving efficiency forecasting ore deposits. Gold particles larger than 0.25 mm with signs wind-worn processing indicate formation autochthonous aeolian placers. size 0.1–0.25 mm, forming an extensive halo dispersion, allochthonous placers Quaternary Deflationary (autochthonous) native can be found by its distribution toroidal spherical hollow forms, which, course, are criterion The presence disc-shaped lamellar ridgelike edges alluvial typical for heterogeneous origin, formed due deflation proluvial discovery pseudo-ore indicates arrival from intermediate gold-bearing ages not primary sources, determining placer. In modern placers, appearance serve as conglomerates high content. developed method diagnosing genotype morphological characteristics (alluvial, aeolian, pseudo-ore) successfully used industrial geological organizations explore
