Modern and Ancient Dolomite
(Tomaso Bontognali and CrisogonoVasconcelos)

The use of the present as a key to the past is needed to interpret dolomitization more than for any other geologic processes to help understand the origin and distribution of dolomite in the geologic column.  The dolomite controversy has remained an enigma in sedimentology for the last 200+25 years. Many field studies have been conducted in modern carbonate environments, as well as in laboratory experiments using both biotic and abiotic parameters, to explain possible ancient geologic paremeters that facilitated dolomite precipitation under Earth’s surface conditions.  This session seeks contributions that provide a better understanding of the (bio)geochemical reaction pathways and environmental controls on the precipitation of dolomite in lacustrine, marine and early diagenetic sedimentary environments.

Carbonate and Dolomite Reservoirs
(Sylvia Anjos and Steve Bachtel)

Carbonates reservoirs often are characterized by properties varying at different spatial scales. We are seeking contributions that demonstrate the controls over the spatial variability in reservoir properties at different scales. Furthermore, contributions focusing on petrophysical properties and pore-scale processes are   encouraged.

3

Carbonate slopes, fans and basins: depositional systems and archives through time
(Christian Betzler and John Reijmer)

In this session we seek contributions to provide a better understanding of the carbonate gravity depositional systems  and their record in carbonate slopes, fans and basins through time. Slopes deposits are a volumetrically significant part of a carbonate platform and important for the stratigraphic correlation between the shallow platform and the adjacent basinal environments. High-resolution seafloor mapping, seismic data, oceanographic data and sedimentological sampling from modern slopes, as well as detailed and comprehensive outcrop studies of exhumed platforms allowed to significantly amend platform slopes, fans and basin depositional models during the last years. We aim to highlight research on the steering mechanisms of sediment variations and stacking patterns of gravity induced submarine fan systems associated with different types of carbonate platforms. Contributions related to the seismo-stratigraphic facies and architectures associated to specific gravity carbonate systems are also welcomed as well as studies on the reservoir properties or rock properties prediction of these deep-water sedimentary systems.

Microbial carbonates and carbonate mounds: deposition and diagenesis
(Anneleen Foubert)

Microbes play an important role in the global carbonate factory. They occur through Earth History and can survive in the most diverse and extreme settings. During the last decades the role of microbes and microbial-mediated precipitation within the global carbonate factory evoked a lot of discussion. This session seeks contributions focusing on (1) the influence of microbes on carbonate deposition, (2) microbe-mineral interactions, and (3) how microbes impact diagenetic processes.

5

Environmental signals in modern and ancient carbonates
(Maria Mutti & Brad Opdyke )

Carbonate sediment production is closely tied to the environmental conditions in which the producing biota exist. Oceanographic, biogeochemical and climatic boundary conditions determine a wide spectrum of environmental factors controlling the nature and evolution of carbonate systems. We seek contributions that using sedimentological, biogenic and geochemical proxies highlight the role of environmental signals in modern and ancient carbonate settings.

6

Novel geochemical tools and approaches to understand dolomitisation
(Stefano Bernasconi)

The last decade has seen the emergence of new geochemical tools and approaches to better understand the conditions of dolomite formation.  We are seeking contributions describing the development and application of novel tools ( e.g. Clumped isotopes, Mg,  Ca isotopes, trace elements) to study determine the temperature and conditions of dolomite formation in the geologic record and in the laboratory.

7

Diagenetic minerals as archives
(Bob Goldstein, Adrian Immenhauser, Fiona Withaker)

Carbonates minerals precipitated from fluids in the shallow marine to deep burial domain yield evidence on physico-chemical parameters in the form of geochemical, mineralogical, and crystallographical proxy data. A general interest in these archives results from the fact that information gained from these precipitates may shed light on the degree of post-depositional overprint of e.g. marine biogenic phases. Alternatively, evidence on diagenetic pathways in the burial domain is relevant from an applied perspective. Early marine to deep burial dolomites are amongst the most significant of these diagenetic minerals.

Ecology and environments of carbonate producers
(Werner Piller)

Carbonate sediments and rocks are essentially built by bioclasts or by biotically induced carbonate precipitates. Since biota have very particular ecological needs defining a specific ecospace their presence and activity provides information on the (palaeo)environment. The session welcomes all presentations dealing with biotic carbonate genesis and related (palaeo)environmental interpretation.

Carbonate platforms through space and time
(Marc Aurell, Evan Franseen, Charlie Kerans)

Sedimentation on carbonate platforms has varied through space and time due to the complex interaction of climate, tectonics and sea-level changes combined to biological evolution. We look here for contributions showing the key factors controlling the development of particular carbonate platforms. These well documented case studies should provide additional dataset to increase our understanding on the different types of carbonate platforms geometry, facies heterogeneities and stacking pattern of facies.  We seek a mix of outcrop and  subsurface contributions, including those that show 3-D aspects of sequences (e.g. seismic geomorphology), quantify sequence stratigraphy (e.g. modeling approaches), and those that highlight the importance of the various factors and processes that control carbonate sequence development. Readily available high-quality digital data from outcrop analogues from different depositional environments is in high demand and serves as an essential input for many subsurface studies where information is usually scarce. In addition, these “Digital Geology” data sets allow us to make such information readily available on-demand. At the same time, technological explosions in drone-related imagery and hyperspectral mapping coupled with high-performance photogrammetry has spurred rapid advances in digital modeling of such outcrops. Combined with increased power and flexibility of subsurface modeling tools, expectations for a new generation of realistic static geological models are high. We hope to highlight important examples of such advances.

Lacustrine carbonate and dolomite
(Rick Sarg)

Lacustrine systems have received renewed study because of growing interest in paleo-climate as well as from their ability to store large quantities of organic-C. Carbonates are key recorders of lake water chemistry and many of these undergo dolomitization in association with organic productivity. We are seeking contributions describing and interpreting the origin of dolomite in lake systems that may range from the modern into the ancient.
