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

摘要

In the Jurassic due to important plate tectonic processes remarkable changes took place in the setting of the tectonostratigraphic units in the Circum-Pannonian (Alpine-Carpathian-Pannonian-Dinaridic) domain. These changes were mostly controlled by coeval closure of the westernmost part of the Neotethys Ocean in the eastern Mediterranean region and the opening of the Piemont-Penninic Ocean as an eastern continuation of the early Atlantic Ocean in the western Mediterranean area. The aim of the present paper is to briefly summarize the main characteristics of the Jurassic successions of the tectonostratigraphic units, referring to the recognized affinities and relationships among the units. Demonstration of the stratigraphy and basic facies pattern is facilitated by simplified lithofacies columns for the units defined. This review may provide a base for an interpretation of the Jurassic evolutionary history of the studied domain and for better paleogeographic reconstructions. A brief summary of the evolutionary history is given.
