Genetic analysis and sedimentary rhythms of Chekardian formation in the typical Chekarda section (Perm region)

We present the results of analysis of the typical Chekardian sequence of Koshelevskaya Suite of the Upper Kungurian. Origin of this formation is associated with the deep-water turbidite fan formed in the active tectonic regime. For the purposes of genetic analysis, the geochemical studies of the Chekardian marl were conducted using the pyrolytic Rock-Eval method and the method of the luminescence analysis. The presence of bitumen in the marl was considered as the evidence of their deep origin. The IV order cycles were identified as a result of periodic changes in the sedimentation depth.
