Upper Badenian diatom paleoecolgy of the western part of Central Paratethys

open access: yesGeologija, 2003
In the western part of Central Paratethys, on the territory of Slovenia, the Upper Badenian diatoms occur only in the Kr{ko basin. The diatom paleoecology of the Upper Badenian beds suggests their deposition in the marine littoral, in warm to ...

Multivariate analysis of Miocene sediments: Rákóczi Square, new metro station area, Budapest, Hungary [PDF]

open access: yes, 2011
Miocene siltstone with variable sand content and bentonitic clay is the most abundant sediments encountered at the metro construction site at Rákóczi Square (Budapest). Core logs, drilling reports and records of laboratory analyses were studied to better

Nubecularia‐coralline algal‐serpulid‐microbial bioherms of the Paratethys Sea—Distribution and paleoecological significance (upper Serravallian, upper Sarmatian, Middle Miocene)

open access: yesGeobiology, Volume 22, Issue 2, March/April 2024.
Abstract Nubecularia bioherms represent unique bioconstructions that are restricted to the upper Serravallian of the Paratethys and have been reported since the 19th century. They occur in the Central Paratethys in the late Sarmatian and the Eastern Paratethys in the Bessarabian both regional stages of the respective Paratethyan areas.

Middle Miocene (Upper Badenian/Sarmatian) Palaeoecology and Evolution of the Environments in the Area of Medvednica Mt. (North Croatia)

open access: yesGeologia Croatica, 2006
In the area of Medvednica Mt., the Upper Badenian and Sarmatiandeposits are divided into four facies associations: (A) deposits of asmall carbonate platform represented by breccia, conglomerates, biocalcirudites,biocalcarenites and biocalclutites; (B ...

Facies and geochemistry of non-marine gypsum, EMISAL, Egypt [PDF]

open access: yes, 2013
Diverse gypsum facies in terms of crystal size and morphology are deposited in a shallow, non-marine, sulfate-enriched, semi-closed, perennial evaporite basin. These gypsum facies were deposited in intimate association with cyanobacterial mats.

Piecing the barcoding puzzle of Palearctic water frogs (Pelophylax) sheds light on amphibian biogeography and global invasions

open access: yesGlobal Change Biology, Volume 30, Issue 3, March 2024.
By revisiting three decades of molecular data, we retraced the evolution and mapped the diversity of Pelophylax water frogs, a famous group of Eurasian amphibians. The results highlight the Paratethys Paleo‐sea as a major driver of diversification, implement a new timetree validation approach, emphasize the rare ability of lineages to hybridize despite

Significance of the Badenian petroleum source rocks from the Krndija Mt. (Pannonian Basin, Croatia)

open access: yesGeologia Croatica, 2010
Discovery of petroleum source rocks at surface exposures of the Badenian deposits on the northern slopes of Krn dija Mt. is the first first record of petroleum source rocks at outcrop in the Croatian part of the Pannonnian basin.

Stochastical approach in deterministic calculation of geological risk - theory and example [PDF]

open access: yes, 2009
Za izračun geološkoga rizika (ili vjerojatnosti, engl. skr. POS) otkrića ugljikovodika u postojećem ili novome stratigrafskom intervalu ili izglednom području unutar Dravske depresije upotrijebljen je dobro poznati deterministički postupak.

Geology of the historical Bodrogköz [PDF]

open access: yes, 2008
The Bodrogköz is predominantly a flat area surrounded by the rivers Tisza, Bodrog and Latorica. The Hungarian-Slovakian border cuts it into two parts; consequently, the geologic data in the two countries are different in terms of scale and in approach ...

Gravity inversion by second order approximation applied to the Styrian Basin (Austria)

open access: yesGeophysical Prospecting, Volume 72, Issue 2, Page 791-808, February 2024.
Abstract An approximative second order gravity inversion scheme by a truncated power series expansion is applied to derive the thickness of the Neogene, mostly clastic, sedimentary section of the Styrian Basins in South–East Austria, which are sub‐basins of the Pannonian Basin System.
