Abstract: Numerous research works have been carried out in the study area for decades.The article is devoted to a detailed analysis and assessment of placer gold content in the main river basins of the Nakhchivan Autonomous Republic, their primary sources, typomorphic features of placers, etc.This investigated the relationship of gold placers with their primary sources.The Bashkendchay and Alidzhachay river basins with tributaries for placer gold have been explored, promising areas have been identified.As a result of the research, it has been shown that these zones are highly promising.In the course of the studies, the typomorphic features of placer gold were revealed: detrital, oblate-detrital, porous, isometric, dendritic, elongated dendritic, etc., the chemical composition of gold was determined by local micro-X-ray spectral analysis.According to the results of spectral analysis, copper, mercury, lead, antimony, etc. were identified as impurity elements in the composition of gold.Bi, Cu, Fe, Hg, Mn, Rb, Sb, Te are the impurity elements in the composition of gold according to quantitative spectral analysis.The studies led to the conclusion that the location of primary deposits and manifestations of the study area close to each other determines the close location of placer gold accumulations.The considered typomorphic features, size classes, high fineness, limited fineness, a small amount of impurity elements, monogranular internal structure of alluvial gold also indicate a connection with nearby primary sources.Placer gold with high prospects is concentrated mainly in alluvial, alluvial-proluvial deposits.
