The Central Kolyma gold region hosts major Natalka and Pavlik deposits, which have a similar structure. Detailed observations in the quarry and in the core of the Pavlik deposit made it possible to outline the stages of structure and mineral formation and compare gold formation process to the left-lateral stage
of development when transformation of previously formed feathering uprise-thrusts and uplift-shifts into lustric fault-shifts took place. In the ore-controlled, complex structure zone of tectonic disturbances, rodlike uplift-thrusts and zones of volumetric fracturing between them were identified. Selected areas of the maximum gold values extending from north-east to south-west trace palaeofluid flows, allow to predict ore mineralization development and adjust exploration drilling direction.
