Special features of the Lebedinsky type gold mineralization occurrence in Dzhekondinsky ore cluster (Central Aldan ore district)

This paper displays structural and compositional characteristics of Lebedinsky type gold ore occurrences in Dzhekondinsky ore cluster. It means that the later one, by its geological structure and combining ore­controlling factor, is analogous to the Lebedinsky ore cluster. Gold ore­bodies are controlled by Dzhekondinsky regional fault and characterized by the general north or northwest strike. Podgolechnoe deposit is the largest one and the single actively mined deposit in there. There are two types of gold mineralization of this deposit: the Lebedisky type ore­bodies are represented by gold­bearing pyrite (limonite)­carbonate­talc metasomatites, sulphide veins and mineralized dykes; pyrite­fluorite­adular metasomatites of the second type are located in rocks of the basement.
Keywords: gold, Lebedinsky mineralization type, Podgolechnoe deposit, Dzhekondinsky ore cluster, South Yakutia.
