Morphological redescription of givetian miospore of the Central devonian fields

Abstract

As part of the work on the ODP-200, complex biostratigraphic studies of Middle Devonian sediments were conducted in the Central Devonian field. Now it is possible to expand andgjk detail the paly-nological studies of the givetian deposits of the studied territory based on the study of new core material. The article provides a morphological redescription of stratigraphically important myospores for the dismemberment and correlation of the givetian sediments (Ardatov, Mullin horizons) of the Middle Devonian. New descriptions and images of myospores, taking into account their morphological features, and translation into a modern nomenclature are given. The results of the research allow us to update the taxonomy of dispersed myospores and provide more substantiated results of the pentiratigraphic studies. The obtained palynological data can be used in the mapping of the ODP-200 and a series of legends to them for the Voronezh antecline, as well as used in correlating local patterns with regional stratigraphic patterns of the givetian sediments of the East European Platform.
