Coral biostromes of the Upper Frasnian Voronezh Formation of the Prypiat Trough (Belarus)

This article presents a schematic model of zoogenic sedimentary deposits common in the Voronezh Formation (Upper Frasnian, Upper Devonian) of the Prypiat Trough. Layered carbonate bodies, in which limestone intervals with abundant ramose Tabulate and fasciculate Rugose corals alternate with intervals devoid of coral remains, represent them. These structures are considered multilayered coral biostromes. Certain features of the deposits and the preservation of coral skeletons within them indicate an active sedimentation environment, particularly the influence of hydrodynamic and, likely, seismic factors. It is suggested that the multilayered biostromes may have been confined to active fault zones of the Voronezh time.
