Stratigraphy of Jurassic Sediments of the Southern Siberian Platform (Russia) Studied through Lithologic and Paleobotanical Data
This paper presents the results of comprehensive lithologic and paleobotanical study of Jurassic sediments of the Irkutsk Coal Basin revealed in outcrops and sections within operating coal deposits. The lithologic characteristics of the main stratigraphic units of the Irkutsk Basin: Cheremkhovskaya, Prisayanskaya, and Kudinskaya Formations are given. Two uneven‐aged fossil plant assemblages: Cheremkhovo for middle and upper subformations of Cheremkhovskaya Formation and Prisayan for Prisayanskaya and Kudinskaya Formations have been identified. Equisetites lateralis (Phill.) Phill., E. asiaticus Pryn., Cladophlebis haiburnensis (L. et H.) Sew., Sphenobaiera czekanowskiana (Heer) Flor., S. vigentis Kiritch. et Bat., Czekanowskia baikalica Kiritch. et Samyl., and Cz. rigida Heer species are typical of the Cheremkhovo assemblage. The age of sediments including the Cheremkhovo assemblage is the end of Early Jurassic (conventionally, Toarcian). Coniopteris maakiana (Heer) Pryn. emend. Kiritch. et Trav., C. murrayana (Brongn.) Brongn., C. spectabilis Brick., Cladophlebis nebbensis (Brongn.) Nath., Raphaelia diamensis Sew., R. tapkensis (Heer) Pryn. emend Kost., Phoenicopsis angustifolia Heer, Ph. cognata Kiritch., and Ph. irkutensis Dolud. et Rasskaz species are characteristic of the Prisayan assemblage. Prisayan assemblage sediments are dated at the beginning of Middle Jurassic (conventionally, Aalenian). The stratigraphic correlation of Jurassic sediments of the Irkutsk Coal Basin with the sedimentary basins of Western Siberia has been carried out based on paleobotanical data.
