Influence of the Frasnian - Famennian extinction event on the reef development within the Pechora syneclise

Abstract

In a complex and diverse reef community composition the biogenic nature of the deposition of the carbonate material is the most evident. Biotic crises, after which a significant evolutionary update of the organic world took place, also affected sedimentary processes. An analysis of the data on the upper Devonian reefs of the studied region has led to the conclusion about the absence of a direct relationship between the mass extinction event and the Upper Frasnian reef development within the Pechora syneclise.
