First Data on the Raman Microspectrometry of Ore-Forming Fluids of Gold and Uranium Mineralizations in Aldan (Republic of Sakha, Yakutia)

摘要

The central Aldan gold-uranium ore district (Sakha Republic, Yakutia) is characterized by a unique juxtaposition of gold and uranium mineralizations genetically related to the Mesozoic alkaline magmatism. However, data on the formation conditions of these two mineralization types in the Aldan Shield are very rare. The available data are mainly related to the thermal regime. We investigated fluid inclusions in minerals of the Samolazovskoe gold deposit located in the southern area of the central Aldan region and obtained new data on the evolution of fluid composition in the course of endogenous gold and uranium mineralizations.
