Drainage network development in the Pannonian Basin

Hungarian Geographical Bulletin, 2015
The evolution and development of the greatest rivers in the Pannonian Basin have been investigated for almost 150 years. At the end of the Late Miocene Sub-Epoch (7.5-5.3 Ma BP) and at the beginning of Pliocene Epoch (5.3-4.5 Ma BP) Lake Pannon shrank ...

Stratigraphy of Aptian and Albian Stages in the central part of Moesian Platform

Geologica Balcanica, 1990
Aptian Stage is widespread in the Central North Bulgaria, while the Albian is established only in the northern regions. The Aptian sections are built up of sediments of the Trambes and Svištov Formations. It has been established that the Trâmbeš and Svištov Formation join laterally along the line Svištov-Tatari-Osilm.
