Triassic Evolution of the Tectonostratigraphic Units of the Circum-Pannonian Region

摘要

After a long lasting continental rifting stage from the Middle Permian to the early Middle Triassic, the opening of the Neotethys Ocean commenced during the Middle Triassic in the Circum-Pannonian area. It was followed by spreading of the oceanic basement and typical passive margin evolution during the Late Triassic. The aim of this paper is to summarize the basic characteristics of the Triassic successions of the tectonostratigraphic units, together with interpretation of the paleoenvironments providing data for the facies polarity of the units and through this for the paleoreconstructions. The characterization is supported by lithofacies columns of the units and photos on the typical facies. There is a short summary of the evolutionary history.
