摘要: The paper reports petrochemical and isotope data on the ferromanganese ores host volcanosedimentary rocks of Taloi–Usoi interfluve Ikat terrane, Central Asian Fold Belt. Obtained indicate that formation Taloi mineralization was related to explosive volcanic activity synsedimentation suprasubduction volcanism. age volcanogenic is 799 ± 3 Ma. This indicates manifestation Neoproterozoic (Riphean) epoch manganese accumulation active continental margin setting in Transbaikalian segment CAFB.
