V. G. Nikolaev, D. Vass, D. Pogacsas. The Neogene-Quaternary Pannonian basin: a structure of labigenic type. The Neogene-Quaternary sedimentary cover is subdivided into two structural complexes: the lower – Miocene and the upper one, including a part of the Upper Miocene, Pliocene and Quaternary. Narrow relatively elongated structures are typical for the lower complex. The linear zones composed of andesite and rhyolite volcanites developed synchronously. The upper complex forms very gentle isometric structures. Their formation was accompanied by the widespread basaltic volcanism. The maximum thickness of the lower complex deposits is associated with marginal structures of the basin, while that of the upper complex was found in its central part.
The Miocene (up to the Sarmatian) is characterized by conditions of extension, while the time of formation of the upper complex, predominantly by vertical negative movements.
The analysis of the structure in the deep-seated part of the Earth's crust suggests that its formation began in the Middle Miocene (the main stage – Upper Miocene/Pliocene) due to the uplift of the mantle diapir. The Pannonian basin, as well as basins of the internal seas of the Mediterranean belt, should be ascribed to a peculiar class of labigenic structures.
