As an important part of the science program of Jurassic 2022, a selection of optional one-, two- or three-day pre- and post-congress field trips will be offered to showcase the Jurassic rocks and fossils in Hungary. Those delegates who cannot afford the extra time will still have a chance to get up close to a complete Tethyan Jurassic sequence at the Geological Garden of Tata during the mid-conference field trip, included in the program for all.
The organisers reserve the right to alter the time of duration and the program of the tour if organisational matters force them to do so. In addition, the right is reserved to cancel the tour due to insufficient number of registrations received to the mentioned deadline of 30 June. In this case full refund is applicable. Checking the box during the preliminary registration is not considered as a financial order. The application is handled on first come first served basis and limited to 20 persons. Non-paid bookings are not considered. Booking any of the tours below means that you have accepted the terms above.
We are exploring the possibility to offer an exciting field trip across the Western Carpathians, starting in Warsaw and ending in Budapest, primarily for delegates who wish to attend both the Cretaceous and the Jurassic conferences that will take place on successive weeks. Organized jointly with Polish and Slovak colleagues, a special focus will be on the Jurassic-Cretaceous transition.

In the heart of the Transdanubian Range, the Bakony Mountains is a key area for the understanding of Jurassic basin evolution in the western corner of the Neotethys. Subsidence of a disintegrating former carbonate platform gave way to pelagic carbonate sedimentation that was interrupted by the deposition of radiolarian chert. Detailed collections from richly fossiliferous ammonitico rosso sequences helped develop the Tethyan biostratigraphy. As correlative litho- and biofacies are known from the Alps and the Mediterranean region, fossil distributions and structural studies contributed to the understanding of tectonic evolution during the Alpine orogeny. Major global events such as the end-Triassic extinction and Toarcian oceanic anoxic event are also preserved in the local stratigraphic record. This three-day field trip will present a complete overview of stratigraphy, paleontology, and depositional history of an area of global significance for Jurassic studies.
In an area smaller than the Bakony, the Gerecse Hills nevertheless offers a similar overview of the Jurassic evolution of a typical marine basin in the western Neotethys. Within a one-day field trip, we will visit outcrops that span the entire stratigraphy from the Upper Triassic to Lower Cretaceous. In contrast to kilometer-thick Upper Triassic platform carbonates, the entire Jurassic is only a few tens of meters in thickness but varies greatly in completeness or gappiness within a basin of differentiated topography. Ammonoid biostratigraphy, Jurassic events, paleogeographic and tectonic reconstructions are some of the highlights of recent research on the sections to be visited.
The Geological Garden at Tata is a unique place to observe a complete Jurassic succession as part of the Mesozoic stratigraphy of an isolated horst block in the picturesque lakeside town of Tata. An easy walk within the nature conservation area also highlights a prehistoric chert pit that demonstrates that a Jurassic formation was an important natural resource for our forebears.
The main target of this short one-day field trip is the Triassic-Jurassic boundary section at Csővár. As there are relatively few continuous marine sections worldwide across this system boundary, Csővár attracted global attention as one of the first localities where a major carbon isotope excursion was documented. Subsequent integrated stratigraphic studies using different geochemical and paleontological proxies contributed to a better understanding of this major global change event.
The geology of these inselbergs in South Hungary are markedly different from that of the Transdanubian Range. As part of the Tisza unit (or terrane), the Triassic-Jurassic transition is preserved in a terrestrial sequence with economically significant coal deposits in the Mecsek Mountains. The overlying spotted marl is a common hemipelagic lithofacies that provides links to other areas in the European passive margin. A Toarcian black shale bears witness of the global oceanic anoxic event. Mid-Jurassic break-off was likely related to rifting of the “Alpine Tethys” and locally resulted in carbonate deposition in a deeper marine basin and change in the affinity of fossil assemblages. The Villány Hills represent a tectonically distinct unit in close geographic proximity. Its markedly different stratigraphy will be highlighted at the Templom-hegy section known for its rich Callovian ammonoid-bearing bed.
