Abstract

Abstract:

Benxi Formation of Carboniferous in the Ordos Basin has unconventional energy sources， and its sedimentary environment is complex and interactive. Therefore， through the analysis and testing of core samples of typical wells in eastern Ordos Basin， based on the observation of core samples，this study reveals the paleoclimate and the palaleobathymetry environment of shale in Benxi Formation， and discusses the control of sedimentary facies characteristics on the shale development. The results show that the salinity of the palaeobathymetry of Benxi Formation gradually decreases from smaller to bigger， and the salinity of the coal seam water at the top of Hutian Member to Jinci Member gradually changes from saline water to saline water reclamation； redox sensitive parameters（Th/U）of Benxi Formation decrease first and then increase from lower to upper. Hutian Member， Pangou Member and Jinci Member are anoxic environment， oxygen poor anoxic environment and weak redox environment， respectively. The study of ancient water depth（Rb/Zr）shows that the ancient water depth of Benxi Formation changes periodically from lower to upper， and then gradually back to lower again； CaO/（Al₂O₃+MgO）， CIA and other paleoclimate indicators reflect that Benxi Formation has a hot and humid climate. We compared the mineral composition and lithologic combination characteristics of the mud shale under different sedimentary backgrounds of Benxi Formation in eastern Ordos Basin， and further divided the facies into swamp deposit， lagoon-tidal-flat-barrier island mixed sediments， and lagoon-tidal-flat-barrier island-swamp mixed sediments were developed in Hutian Member， Pangou Member and Jinci Member respectively.

Key words: Element geochemical, Shale, Benxi Formation, Sedimentary environment, Ordos Basin
