An insight into the tectonostratigraphic evolution of the Grocka Basin (Serbia, Pannonian Basin System)

Abstract

The Grocka Basin constitutes a link between Belgrade, Podunavlje and South Banat sedimentary realms, and can be considered a southwestern branch of the Pančevo Basin. It has a near complete record of Paratethyan sedimentation, from the Oligo-Miocene to the Holocene. One deep exploratory borehole, the G-1, has been completed in 1985 in the town of Grocka. Since it sampled the basement and all intervals of the basin fill except Quaternary, it was very suited for 1D borehole forward modeling. The obtained results have been interpreted in the light of rift sequence stratigraphy, which shows the „punctuated” subsidence model, with two distinct syn-rift sequences and a long post-rift thermal sag phase, and a possible partial basin inversion during the Quaternary.
