Abstract
- Results of U-Th-Pb LA-ICP-MS analysis of detrital zircons from metasandstones of the Chiney Subgroup (Udokan Group, Aldan Shield) have been obtained. It has been revealed that rocks of the Paleoproterozoic (about 1.90, 1.98, and 2.50 Ga) and Neoarchean (2.55 and 2.72 Ga) were their provenance sources. Deposition of the Chiney Subgroup occurred in the interval 1.87-1.90 Ga and was separated in time from the accumulation of the Kodar Subgroup siliciclastics (2.1-2.3 Ga). [ABSTRACT FROM AUTHOR]
