RCMNS Interim Colloquium - CGS Limnogeology Workshop
LAKE - BASIN - EVOLUTION
Stratigraphy, Geodynamics, Climate, and Diversity of Past and Recent Lacustrine Systems
20-24 May 2016, Zagreb / Croatia
Lacustrine basins are dynamic depositional systems depending on regional climate and geodynamic settings. Isolation may lead to diversification of endemic faunas that complicate biostratigraphic correlations and palaeoecological assessments. Even today, age constraints for a number of prominent lacustrine complexes are inadequately resolved. Improved time resolution relies on the thorough integration of multiproxy data.
From that reason, the Regional Committee on Mediterranean Neogene Stratigraphy (RCMNS) decided to devote a special interim colloquium to this particular topic. The Dinarides area of Croatia provides the ideal geological setting of an active fold and thrust belt that separated the Mediterranean and Paratethys basins and recorded an extended history in lacustrine deposition.
The Croatian Geological Society (CGS) represented the key partner responsible for the on-site organization of this meeting, which became integrated into its CGS Limnogeology Workshop. Beside RCMNS and CGS as parent organisations, a great number of national and international scientific bodies and companies became active supporters and sponsors of the meeting – University of Zagreb (Faculty of Mining, Geology and Petroleum Engineering, Faculty of Science), Croatian Natural History Museum, Natural History Museum Vienna, INA-Industrija nafte, Zagreb Tourist Board, Croatian Geological Survey, International Union of Sedimentologists, and International Union of Geological Sciences.
Mediterranean and Paratethyan basins contain spectacular examples how geodynamic processes controlled duration and depositional modes in lacustrine systems. Several of the Neogene-Quaternary lakes became evolutionary hotspots. Large-scale research projects such as the Lake Ohrid deep drilling (SCOPSCO, PI Thomas Wilke), the Freshwater Gastropods of the European Neogene (FreshGEN, PI Mathias Harzhauser), the Pontocaspian biodiversity Rise and Demise (PRIDE, PI Frank Wesselingh), and the Evolution of the Paratethys (NWO, PI Wout Krijgsman) show the interest in lacustrine system and biotic evolution.
The 2016 RCMNS Interim Colloquium brought together a variety of experts and disciplines in lacustrine basin research. Stratigraphers, sedimentologists, structural geologists, paleontologists, biologists and geochemists presented their current results and shared experience. This event provided insight into the state of the art of the still underexplored field of limnogeology and put forward the initiative for integration of constantly growing limnogeological knowledge into a modern synthesis.

Zagreb is the capitol and the largest city of Croatia with a population of c. 800,000 people. It has oceanic climate and the daily mean temperature in May is 16°C. It lies at an elevation of c. 122 m asl in the southwestern Pannonian Basin. Zagreb's historical core, dated to 1094 AD, was built on the southern slope of the inselberg Medvednica (1,033 m asl). In the late 19th century, as an important administrative center of the Austro-Hungarian Empire, it started to spread extensively into the alluvial plane of the Sava River. Indeed, the city center - where the conference takes place - with its monuments and parks is a heritage of that particular time. The extant Croatia is a member of the European Union. Its currency kuna (HRK) has an exchange rate of 0.13 euro (EUR). Due to a spectacular seaside, the country belongs to the 20 most popular tourist destinations in the world.

Session A. Limnogeology - Recent lakes as biotic and climate archives
Lakes are excellent paleoenvironmental and evolutionary archives. The sediment accumulation rates in lakes are much higher than in most marine settings and because of their semi-enclosed positions they are sensitive to climate changes. This allows high-resolution studies in which even fluctuations on millennial to decadal scales might be precisely evaluated. Lake environmental histories strongly depend on precipitation, evaporation, and temperature, which are then reflected in the sedimentary, geochemical and faunal records. Particularly, the ancient lake settings provide conditions where sedimentary successions may preserve a long testimony of regional climatic and biotic changes. The present session covers all aspects of limnology, biology, limnogeology, and climate research in Recent lakes.

Session B. Paleobiology - Diversity and environments in past lacustrine ecosystems
Deposits of past lacustrine systems represent windows to ancient continental ecosystems. Spectacular findings have been made from lake deposits, allowing precise reconstruction of faunal and floral evolution on land. Beyond that, in long-lived, isolated conditions, the lakes provide laboratories of evolution, characterized by highly diversified endemic faunas, often displaying spectacular radiations from only a few pioneer taxa. The descendants of these opportunistic pioneers are developing outstanding strategies to conquer ecological niches far beyond the reach of their ancestors. Presentations dealing with organisms and environments related to lacustrine deposits are welcomed in this session.

Session C. Stratigraphy & Historical geology
In long-lived, isolated conditions, aquatic assemblages become progressively endemic, thereby losing their stratigraphic importance. The correlation of these deposits to other regions and to the geological time scale is therefore traditionally rooted in mammal stratigraphy. Yet, the lacustrine successions commonly preserve also volcanic ash falls, allowing their radio-isotopic dating. Integration of biostratigraphic and geochronologic results with magnetostratigraphic or astrochronologic data commonly result in robust regional stratigraphic models. Carefully dated lacustrine histories, often showing much better resolution than marine ones, then can be used for evaluations in a global context. The present session focuses on the dating of lacustrine successions and their representative environmental histories.

Session D. Geodynamics & Sedimentary systems
Origin, type and history of lake basins depend strictly on regional geodynamic settings, controlling the accommodation space of sedimentary systems. Thereby, extensional, as well as compressional tectonic regimes may provide conditions suitable for lake initiation and stability. As a result of the specific physical environment created through tectonic isolation, lacustrine basins hold increased economic values - 10% today's oil production takes place in petroleum source that formed in lakes. As a matter of fact, the most important reservoir rocks in the southern Pannonian Basin oil province are genetically bounded to lake deposits. This session will focus on the structural, sedimentological, and industrial aspects of lake basin analysis.

Excursion 2 – Croatia and Bosnia-Herzegovina (Plitvice – Vrana – Sinj – Livno – Tomislavgrad – Kupres – Bugojno - Kakanj)

Dinarides lakes and basins - from 18 Ma to Present
Excursion 2 will present ongoing limnogeological investigations on the past and present fresh water lacustrine environments represented since the Early Miocene in the karst valleys and intra-mountainous basins of the Dinarides (the so-called Dinaride Lake System). Results from current and ongoing research about their geodynamic, depositional, environmental, and biotic histories will be first-hand presented by its researchers and excursion guides, respectively.
The excursion starts with the World heritage site, the spectacular calcareous tufa cascades of the Plitvice lakes (picture below), situated in the largest national park of Croatia hosting more than 1 million visitors per year. It continues with Lake Vrana, located in a Dalmatian karst valley of the Adriatic coastal area, and represents the largest Croatian fresh water lake. Recent limnogeological drilling campaigns therein allowed precise reconstruction of the regional sea-level history in the Pleistocene. The end of the day will be spent in the Sinj Basin, filled by the coal bearing carbonate deposits of a long-living lake that existed there for about 3 Myrs during the Miocene Climate Optimum.
The second day will demonstrate the rise and fall of the long-lived lacustrine environments in the Livno (picture below) and Tomislavgrad basins in Bosnia-Herzegovina. Beside different sediment types such as coals, marl, carbonates, volcanic ashes and debrites, the visit to the Mio-Pliocene proboscidean site Cebara will bring insights to the complex geodynamic history of these two classical karst valleys of the External Dinarides. A fossil site with excellently preserved 15 Myr old endemic fresh water mollusks will be visited by the end of the day in the Kupres basin.
The third day will start with a visit to the open cast mine Gračanica in the Bugojno basin where large-scale outcrops show transgressive open lake marls with slump structures grading over thick lignite measures, bearing large mammal remains. The rest of the day will be spent in the region of Kakanj in the Sarajevo Basin. This is the largest Dinaride lake basin. The asymmetric extensional basin formed in the hanging-wall of a large-scale top-NNE detachment and is associated with the exhumation of the Mid-Bosnian Schists Mountains in its foot-wall. The field stops will take you from the deep lake to alluvial plains, and thereby illustrate the close connection between tectonics and sedimentation.
After the closing ceremony in the local guest house, the arrival to Zagreb is set to 21:00 at the Faculty of Mining, Geology and Petroleum Engineering, that will be also the starting point of the excursion. The fee covers the field guide, transportation, hotel/pension (twin bedrooms) and boarding costs. Be aware to have a valid visa for Bosnia-Herzegovina, if necessary, before the excursion's start.
