TSUNAMITES IN A STORM-DOMINATED ANISIAN CARBONATE RAMP (VYSOKA FORMATION, MALE KARPATY MTS., WESTERN CARPATHIANS)

Abstract: The Vysoka Formation limestone sequence (Fatric Zone, Central Western Carpathians) reflects two striking contradictions in the character of the Anisian sedimentary record. Tempestite intercalations representing the first one are connected with the occurrence of violent storm events which interrupted the overwhelmingly stable sedimentary conditions of a restricted shallow carbonate ramp environment. The second contradiction (tsunamite layers) proves the occurrence of sudden seismic events which disturbed a long period of rather slow (20–30 mm/Ka) gradual subsidence. These events are interpreted as the effects of starting the oblique rifting of the Paleo-European shelf.
