Comparison of the Jurassic and Lower Cretaceous successions of the Eastern Alps and the Transdanubian Range - Similarities and differences
Guide: Géza Császár
The Transdanubian Range was part of a huge carbonate platform until the earliest Early Jurassic. The first signal of the opening of the Penninic Ocean is the break of the carbonate platform system. The result of this process is the differentiation of the sedimentary environments into highs with comparatively thin, discontinuous and into deeper-water areas with condensed lithofacies, and thicker, less condensed successions.
There are great differences in thickness and also in lithology of the Jurassic lithostratigraphic units in southwest and northeast direction in the Transdanubian Range.
The shallowing tendency started in the Tithonian and continued in the Early Cretaceous in the entire territory of the Transdanubian Range. In the Gerecse Mts flysch-type clastic succession developed in the Early Cretaceous, with limestone fragments containing colonial fossils too. In subsurface conditions this succession also found in South Slovakia too. These successions are similar to those in the Eastern Alps too.
During this time in the South-Bakony, completely different formations developed (Mogyorósdomb Limestone Fm), which is getting thicker and more and more similar to that of the South-Alpine development.
