Abstract
The paper presents new data of petrographic and geochemical features of carbonate deposits in the southeastern part of the Anabar-Sinsk basin. Direct and indirect signs of volcanogenic and exhalation activity synchronous to sedimentogenesis have been identified in the section of Toyonian deposits of the pre-reef slope facies for the first time. Results of the studies allow using positive geochemical Co, Pb, Zn, Ba and Mn anomalies, the values of the HREE/LREE, Ce/Ce* and Eu/Eu* ratios in bedrocks as a search criterion for the lead-zinc Mississippi-Valley-type mineralization within the Sinsk-Botomian Group.
