Abstract

The paper reports data on concentrations of lanthanides in rocks, fluorite, and wolframite from the Spokoininskoe greisen deposit in eastern Transbaikalia. Lanthanide concentrations in the ore-forming fluid are calculated using mineral/fluid distribution coefficients. The data on REE are consistent under the assumption of a single, but evolving, genetic source. The REE concentrations are similar for rocks variably affected by greisenization and are controlled by the solubility of monazite contained in the granite. The younger quartz–albite–muscovite veins and segregations contain elevated concentrations of LREE, which is explained by an increase in the monazite solubility in alkaline solutions during the late evolution of the fluid.
