| Abstract: | The problems of the origin of Au-rich horizons, which host all significant gold-ore deposits of the region, including valuable objects on a global level (Natalka and Nezhdaninskoe deposits), are considered, exemplified by Permian black shale deposits of the Ayan-Yuryakh anticlinorium of the Yana-Kolyma foldbelt and recent bottom sediments of the Chukchi Sea continental shelf. |
