FEATURES OF MICROELEMENT DISTRIBUTION IN LOWER RIPHEAN SANDSTONES OF THE SOUTHEASTERN ANABAR SHIELD

The article presents the results of petrographic and lithogeochemical studies of Late Precambrian terrigenous deposits of the Labaztakh Formation of the Mukun Group in the southeast of the Anabar Shield. The data obtained made it possible to identify epigenetic transformations of the studied rocks and establish that the provenance was acidic igneous rocks, and one of the most likely sources could be granitoids of the Anabar, Billakh and Magan plutonic complexes, which are widespread within the Anabar shield.
