A two-day field excursion will allow us to visit Quaternary marine, lacustrine and fluvial sites in Slovenia, Italy and Croatia.
The excursion will be guided by: Maja Andrič (ZRC SAZU), Dea Brunović (HGI), Nina Caf (ZRC SAZU), Igor Felja (PMF), Alessandro Fontana (UNIPD), Ozren Hasan (HGI), Nikolina Ilijanić (HGI), Petra Jamšek Rupnik (GeoZS), Katarina Jerbić (Flinders U.), Jernej Jež (GeoZS), Ida Koncani Uhač (AMI), Slobodan Miko (HGI), Giovanni Monegato (CNR, IGG), Ana Novak (GeoZS, UL NTF), Cesare Ravazzi (IGAG) and Andrej Šmuc (NTF UL).
September 29th, 2021: We will first stop at lake Bohinj where the lake sediments recorded Holocene seismic activity, vegetation and erosion history and the human impact on the environment. At Most na Soči we will see a profile of glaciofluvial and glaciolacustrine sediments and discuss the mechanism responsible for their deformation. Near Gorizia we will visit the Lateglacial terraces which formed in the Soča LGM fluvioglacial fan. At the Renče clay pit we will observe the sedimentary succession which contains one of the best preserved paleovegetation records of the Alpine LGM. Dinner and overnight near nova Gorica.
September 30th, 2021: We will start the second day of the excursion at Tapogliano with an outcrop of the LGM to present day alluvial sequence of the Torre River which contains LGM paleosol. Near Grado we will observe continental LGM dunes which later interacted with Lateglacial fluvial and Holocene lagoonal environments. On the NE part of the Gulf of Trieste we will discuss the post-LGM transgression and the change from fluvial to marine sedimentary environments in the gulf. In the Zambratija bay we will be presented with the latest archeological and paleoenvironmental findings regarding the studies of the prehistoric pile-dwelling settlement, which was submerged by the advancing transgression. Lastly, we will visit the Mirna river valley where transgressional depositional facies were prograded by the Mirna intra-estuarine delta. Transfer to Ljubljana.

Lake Bohinj is the largest permanent natural freshwater lake in Slovenia. It is a glacial lake located in the alpine environment of the Triglav National Park (Julian Alps). This area exhibits high seismic activity and a long tradition of human activity dating back to the Bronze Age. The lake is therefore an ideal archive for studying past environmental changes. We will be presented with the results of recently completed studies of the lake sediments which investigated the Holocene seismic activity, the vegetation and erosion history of the catchment area and the human impact on the environment (Rapuc et al. 2018; Andrič et al. 2020).

Most na Soči: Soča Valley in Most na Soči was affected by exchanging glacial and fluvial processes and by mass wasting phenomena. In addition, the Idrija Fault activity influenced the evolution of drainage. As a result, the valley here hosts various sediments from fluvial, glaciofluvial, glaciolacustrine, glacial and slope deposits. The field stop will visit a profile of glaciofluvial and glaciolacustrine sediments, which were tilted and dissected by series of faults. Mechanisms responsible for observed deformations will be discussed.

Gorizia: Terraces in vicinity of the city of Gorizia were cut during the Lateglacial into the Soča (Isonzo) fluvioglacial fan which is related to the Last Glacial Maximum (LGM). The 30 m high terrace scarps at Gorizia show a thick succession of well bedded gravels which are locally cemented.
Renče: The sedimentary succession at the Renče clay pit shows alternate laminated silty-clay and sandy lenses. The chronology points to an aggradation between 26 to 22 ka cal BP driven by the aggradation of the Soča (Isonzo) river fluvioglacial fan in Gorizia. The paleobotanical macroremains represent one of the best palaeovegetation records of the Alpine LGM and, coupled with palynological analysis, indicate the persistence of open forest throughout the cold period.

Tapogliano: In the present channel of Torre River, few kilometers upstream the junction with Soča River (Isonzo), nice outcrops of the alluvial sequence from LGM to the present day are visible on the riverbed and along the banks. Torre River dramatically entrenched in its channel in the last decades because of anthropogenic activity and led alluvial stratigraphy to be exposed. In this site it is possible to see the characters of the soil developed at the top of LGM sequence and the traces of archaeological activity.

Grado: Dunes of San Marco and Belvedere near Grado are a complex of sand dunes facing the Lagoon of Grado and Marano, where, according to the legend, Saint March landed for reaching the city of Aquileia. These landforms, strongly reworked in the last centuries, have a maximum height of 8 m a.s.l. and are one of the most peculiar sites in the coastal plain of NE Italy. The dunes display some evidence of aeolian processes and have been probably formed in continental conditions during the end of the LGM. Later, since Late Glacial, they have been surrounded by fluvial units of Soča River (Isonzo) and by the Holocene lagoon deposits. The site is a nice location to discuss about the interaction between different factors involved in the formation of coastal plains, as sea-level changes, alluvial inputs and tectonics.
Gulf of Trieste: The Gulf of Trieste, also the northeasternmost part of the Adriatic Sea, is presently a shallow gulf bordering on Italy, Slovenia and Croatia. During the Late Quaternary the area of the gulf along with the rest of the northern Adriatic represented the vast alluvial plain of the river Po and its confluences which was later submerged by the post-LGM transgression. Acoustic investigations of the present-day seafloor in the gulf have shown spectacularly preserved pre-transgressional fluvial features. Results of the most recent studies show that fluvial activity in this area persisted up until the Younger Dryas.

Zambratija: The oldest archaeological site in Zambratija Bay is a submerged prehistoric pile-dwelling settlement which was in use between around 4200 and 3700 years BC. The remains lie on the outer edges of a submerged karstic sinkhole (doline). The site was initially recognised after finding a large number of finds such as pottery fragments, stone tools, as well as more than one hundred in situ wooden piles protruding out of the seabed and peat platform. Interdisciplinary investigations showed that during the occupation the settlement was still a terrestrial/wetland environment and that the abandonment of the pile-dwelling is chronologically connected with the marine transgression which happened sometime in mid-4th century BC. Other archaeological finds have also been discovered on the ridges in Zambratija Cove, indicating the continuity of human settlement all the way from the Bronze Age to the Roman period, when the ridges were part of the mainland. A 72-metre long structure interpreted as a probable Roman road has been preserved along the natural limestone reef that spreads towards the western side of the coast. The cove is also known for the discovery of the Zambratija boat, the oldest example of a completely sewn boat found in the Mediterranean, which was discovered in 2008 at a depth of around 2 meters. The hull remains measure 6.7 m in length and 1.6 m in width at the widest section.

Geological research in Zambratija Bay was based on geophysical surveys and seabed sediment coring. Sediment thickness in the submerged sinkhole reached up to 8 metres. One 5.7-metre sinkhole sediment core sample contains the record of paleoenvironmental and sea-level rise changes throughout the Holocene. Brown clay and terrestrial wetland and freshwater lake sediments were superimposed with thick marine sediments, deposited during the marine transgression since mid- to late Holocene until present times. The brown clay, which is situated at the very bottom of the sinkhole, represents the soil layer which served as foundation for prehistoric settlement wooden piles, found in situ. Lastly, indications of coastal freshwater springs in the bay provided additional environmental evidence for a sustainable lifestyle at the time of settlement occupation.

Mirna: Sedimentological, macro- and micropaleontological analyses on sediment cores were carried out in the lower section of the Mirna River valley, in order to study depositional facies and environmental evolution during Late Pleistocene and Holocene. The Holocene marine transgression reached river valley several kilometers upstream from the present-day coast, while in the last 7000 – 6000 years it was followed by progradation of the Mirna intra-estuarine delta. Sediment cores recorded these changes and each depositional environment contains distinctive sedimentary characteristics and fossil assemblages which reflect conditions in which sedimentation and life were occurring. This study highlights the potential role of hand augering in sampling and describing the subsoil for reconstruction of the geomorphological evolution of the area and supporting the study of past relative sea levels, climate changes, and impact of anthropogenic activities.
