Chronozonal Structure of the Mangazeya Superhorizon in Eastern Siberia and Its Place in the Global Ordovician Scale

Abstract —The chronozonal structure of the Mangazeya Superhorizon of Eastern Siberia, which includes the Listvyazhny and Baksan horizons and their chronozones, is considered. Their volumes and stratotypes are given and their place in the regional and global stratigraphic structure is shown, where Mangazeya occupies the middle parts of the Kuzmovsky regional complex and the Caradocian stage of the Upper Ordovician. Proper names for the Lower Dolbor Horizon (Amutkansky) and the Upper Dolbor Horizon (Cherlechinsky) are introduced for the first time.

期刊介绍： The journal publishes original reports of theoretical and methodological nature in the fields of geology, geophysics, and geochemistry, which contain data on composition and structure of the Earth''s crust and mantle, describes processes of formation and general regularities of commercial mineral occurrences, investigations on development and application of geological-geophysical methods for their revealing. As to works of regional nature, accelerated publication are available for original papers on a variety of problems of comparative geology taking into account specific character of Siberia, adjacent Asian countries and water areas. The journal will also publish reviews, critical articles, chronicle of the most important scientific events, and advertisements.
