The Devonian of Transbaikal: biostratigraphy and correlation

Abstract

Devonian deposits of Transbaikal, eastern Russia, within the Mongol-Okhotsk fold belt and adjacent areas have been studied. New data on the composition, age, and structure of Devonian marine formations is given, and a modern synthesis of the stratigraphy is proposed. The palaeontological characterisation of the formations is detailed, regional and interregional correlations are proposed. The presence of characteristic palynological associations and often of index-species for these palynozones makes it possible to date and correlate the stratigraphic units of the Eastern and Western Transbaikal and to trace them to the East European Platform.
