The structural features, lithological composition and sedimentation conditions of the Kuonamka Formation were identified in the analysis of core material uncovered by wells in the east of Anabar oil-and-gas region in the basin of the Kyulenke River. It was established that the studied highly carbonaceous rocks accumulated in deep-water conditions of the open sea in reducing, mainly euxinic environments.
