3rd School on Sandstone Diagenesis
The Applied Sedimentology Group at the GeoZentrum NordBayern (FAU Erlangen-Nuremberg) and Geocosm LLC. are happy to announce the 3rd School on the Diagenesis of Silicilastic Sediments. The first and second edition were a success. We received motivated geoscientists from both University and Industry from all over the world. The third edition will be held as usual at the Geozentrum Nordbayern in Erlangen (Nuremberg, Germany). As for the second edition, the school will last for 5 days, from the 7th to the 11th of September 2020, and will focus on both traditional and innovative concepts for controlling processes on sandstone diagenesis and their implications for data interpretation and modeling.
For the third consecutive year, the school is supported by the International Association of Sedimentologists (IAS) in the past. We greatly value their financial support to the student members that already allowed the participation of early career geoscientists from the USA, South America, the EU, and SE Asia.

While the definition of diagenesis – the transformation of unconsolidated sediment to rock – is easily understood, the factors that influence the nature and magnitude of this transformation are complex. In this school, we will review the state-of-the-art in our understanding of many of these factors in sandstones. Such an understanding is an essential prerequisite for accurately predicting rock properties in the subsurface and has important societal applications in topics as diverse as aquifer depletion, wastewater disposal, contaminant transport, hydrothermal energy production, and hydrocarbon exploration and production.
Why a holistic approach?
Although diagenesis in a strict sense refers to biological, chemical, and physical processes that occur after deposition, the nature and magnitude of these processes is inextricably linked to the starting composition and texture of the sediment. To date, little has been done to bring together two critical aspects of sandstone reservoir quality prediction: the controls on the depositional composition and texture and the post-depositional overprint of diagenesis. An important and novel aspect of this course is to bring together experts in these two disciplines to provide course participants with a review of both parts of the reservoir quality prediction problem.
Processes That Control Depositional Composition and Texture
Depositional composition and texture constrain fundamental rock properties such as porosity and permeability of the nature and magnitude of diagenesis from shallow to deep burial. The starting point in understanding and predicting sediment depositional characteristics is an analysis of the genetic origin of the sedimentary input. The Sediment Routing System concept is being increasingly invoked in basin analysis and related geodynamic studies, as the variable input of sedimentation through time-affected basin development, sediment accumulation and distribution, burial, subsidence, flexural rebound, isostasy, denudation and other geodynamic effects.A comprehensive understanding of sediment generation – in its broader sense – thus represents the only possible way to achieve a solid prediction of sedimentary texture and composition. Further More, its integration into a Sediment Routing System conceptual framework allows understanding and possibly predict the distribution of sediment particles within the subset of facies of a sedimentary environment, identification of sediment-induced heterogeneities, and eventually the initial composition of deposited sediments (eg, sand framework composition, clay abundance, etc.) and how this would affect early diagenesis.The ultimate composition and texture of sediments, however, depends on the provenance and final depositional environment but also on factors such as tectonic setting, climate, and transport history. Important changes in depositional composition and texture may take place even within the same depositional facies in response to variations in search factors.
As sediments are buried they deform and alter in response to the evolving stresses, temperatures, and fluid chemistries that they experience through geologic time. The impact of these processes on rock properties can be immense. For instance, permeability in sandstones may drop by over six orders of magnitude from the time of deposition to the present-day.
The initial composition and texture influence the mechanical and chemical properties of the sediment, which in turn may lead to substantial differences in the nature and magnitude of diagenetic change through time. For instance, grain shapes, size distributions, and material properties influence the depositional packing state as well as the magnitude of compaction that occurs in response to stress and the geochemical reactions that take place as a function of time and temperature. In the course we will review controls on depositional packing state, compaction, and reactions involving carbonates, clay minerals, and quartz overgrowths, among other diagenetic processes.
Models serve as a means to encode and test our understanding of nature and have the potential to serve as an accurate basis for prediction. In the course we want to consider two broad groups of models associated with sandstone reservoir quality prediction. The theory of spatial distribution of compositional and textural characteristics of sands. The second group of models includes the post-burial lithification of sandstones in light of the depositional composition and texture and in response to the cumulative effects of stresses, temperatures, and fluid compositions through geologic time. Models that link the predicted composition and texture of diagenetically altered sandstones to properties of interest in fluid transport, geomechanics, petrophysics, and geophysics are thus an important component of this group.
This is year we have included a set of lectures and exercises focusing on a third group of model: Basin analysis and modeling. Our new partner Schlumberger will provide experts in the fields of (i) basin-forming mechanisms and basin fill, (ii) pressure and compaction in sediments, (iii) temperature and temperature history of sedimentary basins, iv) application to hydrocarbon generation, migration and accumulation, and (v) predictive methods.
