From the Dolomites to Etna, from the Venice Lagoon to the Trapani Salt pans, Italy embeds a wide spectrum of deposits and related depositional environments in a very short frame. Illustrations and characterization are due to scientists able to observe and describe such amazing and unique features. Starting from historical precursors as Pliny and Leonardo da Vinci, modern Italian and International sedimentologists have illustrated this richness as case histories used in the geology and heritages for the future.
Aim of the session is to exhibit the Italian sedimentology that spotlighted the geology in the world with the contribution of the international sedimentologists that spotlighted the Italian geology..

Microbialites are fascinating organosedimentary deposits that are present throughout the entire geological marine record. These deposits are typified by a wide spectrum of particular morphologies, in a variety of lithologies (carbonate, clastic, evaporite, phosphorite), and occur in a wide range of marine settings, including shallow and deep water environments as well as in extreme sedimentary environments (i.e. hypersaline and hydrothermal). The interest in microbialites from the scientific community and industry has increased exponentially in recent years because of their significance in unravelling the evolutionary history of life on Earth (and virtually on other planets), and their role in petroleum systems, as source and reservoir rocks. This session encourages contributions on any aspect of modern and fossil marine microbialites, especially where information is coming from different disciplines: sedimentology, geochemistry and geomicrobiology.

Biology influences physical form and process in all of Earth’s present-day sedimentary environments. For example, peat and rooted vegetation provide increased mechanical protection to river banks, promoting the development of deeper, narrower and more sinuous channels. Infaunal burrowers influence the chemical properties of sediment substrates by increasing oxygen circulation, which in turn increases the rate of organic matter decay. Even microbiota have been shown to reduce bedform dimensions and steepness. The objective of this session is to improve our understanding of life’s fundamental role in shaping sedimentary environments. Geomorphological, ecological, geological and experimental contributions are all welcome. We particularly encourage studies which consider life-sediment interactions over evolutionary timescales. The geological timescale provides a handful of ways in which evolving life can be shown to radically alter sedimentary environments. However, the majority of deep-time life- sediment interactions are poorly understood. An improved understanding of life’s influence on sedimentary facies and lithologies will benefit numerous fields of Earth Science (e.g., ongoing investigations of Martian sedimentary outcrops).

Primary and secondary volcaniclastic processes represent the crossroad between volcanological and sedimentological processes, and their influence on the environment is largely recognized. Nevertheless, a gap still exists between sedimentological and volcanological approaches to the same problems.
This session aims to bring together researchers working on volcanic or volcanically influenced terrains to unravel the generation, transport and settling of volcanic particles through the geological time in different environments, in order to narrow this gap.
We invite presentations that include, but are not limited to, 1) field-based description and interpretation of volcanoclastic sediments and related processes both in modern and ancient realms, 2) provenance studies that highlight the influence of volcanic activity on sedimentary basins, 3) studies on the characterization of physico-chemical processes that lead to the generation and weathering of volcaniclastic particles through time.
This session is co-sponsored by the Commission on Volcanogenic Sediment of the International Association of Volcanology and Chemistry of the Earth’s Interior (IAVCEI).

Supercritical flow conditions can occur in open-channel flows, subaqueous density currents, pyroclastic density currents, and katabatic winds, and thus affect a wide range of subaerial and subaqueous depositional settings, e.g. proglacial, fluvial, coastal, deltaic, shallow- to deep-marine, volcaniclastic and carbonate-slope environments. Supercritical flows create upper flow-regime bedforms such as antidunes, chutes-and-pools, cyclic steps and transitional bedforms, whose development and properties are still only partly constrained. Even if a growing number of upper flow-regime bedforms is reported in modern environments, these bedforms and associated sedimentary structures are classically thought to possess a low preservation potential in the stratigraphic record as a result of their high-energy, transient formative conditions. However, recent evidence suggests that the scarcity of available observations may be due to a lack of diagnostic criteria for their recognition. Flume experiments have been pivotal to advancing our understanding of the morphodynamics of upper flow-regime bedforms. Numerical models and direct measurements have also contributed to advance our knowledge of supercritical flows, even if a real integration between the different approaches is still lacking.
This session welcomes field, experimental and numerical studies investigating the sedimentological aspects of modern and ancient upper flow-regime bedforms and their formative supercritical flows. Students and early career scientists are encouraged to submit.

This session describes the sedimentary processes, products and environments associated with past glacial events through Earth’s history, from the Palaeozoic to the present day, including evidence from Pleistocene glaciations. The focus in this session is on the nature of different types of sedimentary evidence (including its geomorphic and stratigraphic contexts) and applications to climate and glaciological reconstruction. Particular emphasis is placed on the role of sedimentary facies properties, sedimentary structures and other evidence for subglacial and proglacial environments and processes, and the role and limitations of modern analogues and numerical models. Contributions to this session are invited from those working on any types of glaciated or glacially-influenced environments, past or present, and from terrestrial or marine settings, or from local to global scales.

The study of sedimentary processes in polar areas contributes to reconstructions of climate, environmental and oceanographic conditions, as well as ice-sheet dynamics on high-latitude continental margins. Such studies can be based on the integration of acoustic data, including swath bathymetry and sub-bottom profiles, seismic data, as well as multi-proxy analyses of sediment cores including drill cores. The rapid response of the polar areas to the recent global climate warming is predicted to accelerate sea-level rise, leading to strong environmental and socio-economic impacts. A thorough knowledge about mechanisms forcing climate change in the past is an essential tool to understand the present state and to predict the future development of the large ice sheets in Antarctica and on Greenland in a geological context. Enhancing this knowledge requires an integrated effort of the scientific community.
The aim of this multi-disciplinary session is to bring together researchers working on northern and southern high-latitude continental margins, investigating the sedimentary processes associated with past and present ice-sheets dynamics and paleo-oceanographic effects on the marine sedimentation from both observational and modelling approaches.

Bottom currents (BCs) and contourite depositional systems (CDSs) are important component of deep ocean basins and continental margins. The last decades have seen significant progresses in the characterization of CDSs and role of bottom currents on sedimentary and geomorphic processes. In order to better address the relationships between oceanographic processes, morpho-sedimentary processes and CDSs development further improvements are, however, still necessary. In this regard, a multidisciplinary approach among many disciplines (sedimentology, seismic stratigraphy, biostratigraphy, geochemistry, physical and biological oceanography, numerical modeling, etc) using high-quality datasets may provide new significant insights.
Contributions from modern and ancient environments (both ancient deposits and outcrops) addressing CDSs nature (e.g., architecture, morphology, stratigraphy, lithology, habitats), mechanisms responsible for their formation and interplay with other processes (e.g., turbidites vs contourites, hemipelagites vs contourites) are welcome. In particular, major topics will be:
1) Link between bottom currents and contourite sedimentation at different scales:
a) Small scale: sedimentological records (e.g., facies, drift accumulation, erosion-reworking) and site survey data (current meter measurements oceanographic transects) showing variability of BCs
b) Large scale: distribution of CDSs and numerical simulations and circulation models (oceanic and regional)
2) CDSs in the sequence stratigraphic framework
3) Relevance for slope stability.

Tidal and non-tidal straits and seaways are challenging geological areas governed by current amplification generated by local oceanographic narrowing and providing uncommon sedimentary conditions. Although the growing interest on such systems due to their potential for production of renewable energy, strategic role for the transport industry, climatic impact on the interconnected basins and many more, straits and seaways lack accurate depositional models predicting their space-time sedimentary dynamics and evolution.
This session is primarily aimed at defining the state of knowledge on the variety of sedimentary processes and distinctive depositional signatures of these systems. Secondly, it wants to provide a chance for stimulating discussions, idea exchanges and joint collaborations between sedimentologists, marine geologists, geophysicists, oceanographers and other researchers involved in the investigation of modern and ancient cases.
After the opening of the key note of Robert W. Dalrymple (Queen’s University, Canada), talks and posters focused on recent breakthroughs, theoretical hydro-sedimentary modeling, interplay between tidal or oceanographic currents and other strait-related processes will be welcome. We also encourage presentations aimed at the re-examination of the recognition criteria of ancient straits in the rock record, the creation of static or dynamic facies-based models, and the discussion of present uncertainties or still unsolved aspects.

Subaqueous mass movements occur in lakes, fjords and oceans of the world, playing a key role in the evolution of coastal areas and continental margins as they represent one of the most efficient mechanisms of sediment transport from coastal to deep basins. The mapping and characterization of such processes has also significant implications for geohazard assessment, because such events can directly impact coastal and offshore infrastructures as well as cause local but destructive tsunamis. The aim of this session is to provide a forum to discuss field (outcrop, core and geophysical), experimental and numerical studies that advance our knowledge on the occurrence, failure and post-failure behaviour of subaqueous mass movements. Particularly we encourage multidisciplinary contributions aimed to assess and mitigate the geohazard potential associated to these processes both at local and regional scale.

Extreme/catastrophic events are by definition rare and episodic, but they have occurred frequently throughout Earth’s history. High magnitude events such as earthquakes, tsunamis, large-scale landslides, extreme floods and storms, extraterrestrial impacts, etc. often leave a sedimentary imprint in the geological record. Nevertheless, recognition of extreme event traces in sedimentary successions is often difficult and may be ambiguous.
This session is focused on examples of seismites, tsunamites, and other sedimentary deposits that have been formed by extreme events. We encourage contributions including field-based examples discussing different approaches on data analysis and interpretation of these deposits. We also welcome studies on analogical modelling and numerical simulation for relationships between triggering processes and products of extreme events.

The aim of this session is to combine the sedimentary and geobiology approaches to reconstruct the past environments, the geological evolution, composition and habitability on other planets. This will also have implications in the study of deep time geological record on Earth.
The current strategy for planetary exploration, which includes a sample return mission from Mars in the next decade, requires the definition of pathways for in situ analysis on planetary surfaces to correctly identify the depositional environments and the habitability potential.This implies a multidisciplinary, integrated approach to successfully address the in situ investigation on other planets.
Furthermore, it is fundamental to identify specific biomarkers associated to different habitability conditions which represent high priority targets for planetary exploration.
Thus, the identification and characterization of terrestrial analogues is mandatory to constrain facies association and evolution on other planets as well as the potential presence and distribution of microbial community.
Contributions addressing sedimentary processes and deposits on planets and the interaction between sedimentological and geobiological processes in complex geoenvironmental settings on Earth, are welcomed in this session.

Sediment and associated particles (e.g. pollutants, nutrients, organic carbon, microplastics) travel along fluvial, lacustrine and coastal environments before reaching the ocean. Each environment has its own sediment transport processes and depositional products, but these also interact over space and time. This session focusses on sedimentological interactions which operate as cascading or domino-like effects. We are interested in work linking processes to products across all physical and time scales, from grain-to-grain interactions to source-to-sink systems and from transient transport to preservation over geological times. We welcome concepts, case studies, numerical and experimental work which connects transport processes to sedimentary products from fluvial all the way to deep marine environments. We also encourage papers which shed light on the societal implications associated with the sedimentological process-to-product-to-process interactions, e.g. transport and fate of microplastics and organic carbon, hazards to human-made infrastructures, ‘reading’ of the geological record in order to make predictions about future behaviour of the Earth system.

Studies in Martian sedimentary geology have never been more active. Orbital imagery has revealed a vast, ancient stratigraphic record and rover missions have enabled detailed sedimentological studies combined with mineralogical and chemical analyses.
A growing list of geomorphic landforms is also known from Titan, though it remains uncertain whether the moon has a more ancient stratigraphic record.
As on Earth, extraterrestrial sedimentary rocks may archive information pertaining to ancient climate, tectonics and potentially, life. Considering ongoing and future exploration missions aim to find potentially habitable environments, sedimentary rock outcrops therefore make desirable targets. This session invites any contribution towards Martian and Titan sedimentary geology and geochemistry. In addition to the classic contributions, we particularly welcome presentations that utilise appropriate Earth analogues, both modern and ancient. As ongoing and upcoming rover missions are providing increased opportunity to study extraterrestrial sedimentary strata, understanding directly accessible Earth analogues from which to base comparisons has never been more essential.

After the full recognition of evaporites as true sediments, and not just chemical precipitates, a large array of sedimentological features have been documented in the last few tens of years, ranging from displacive, intergrowing(related to crystal growth),cumulate, branching, and to any type of clastic, and much more.
Some of the sedimentary features are truly complex and may need to be carefully interpreted, especially after common diagenetic and later transformations, which may deeply change their original appearance.
The goal of this session is to explore the very wide archive of sedimentary and diagenetic features on Earth, which actually represent our reference to understand what we are expecting to find on other planets, where evaporites are known to be present and are just waiting to be described in detail.
