Abstract: The analyzed area of the Riphean paleobasin is located in the western part of the Siberian Platform (East Siberian Basin). The deposits of Derevninskian and Dzurkian formations are represented by platform carbonates of different facies belts and to a minor extent by clastics. The depositional environment included several shallow marine facies of different biogenic zones and hydrodynamic regimes. Lithological characteristics logged in several outcrops, hand pieces and thin sections of the two formations, allow a founded paleo-reconstruction and mapping of the depositional facies within the Riphean basin
