Why Diagenesis?

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 and strongly affect 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 source-to-sink concept has been increasingly invoked in basin analysis and related geodynamic studies, as the variable input of sediments through time affects 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 – therefore represents the only possible way to achieve a solid prediction of sediment texture and composition, its distribution within the sub-set of facies of a certain sedimentary environment, identification of sediment-induced heterogeneities, and eventually the starting composition of deposited sediments (e.g. sand framework composition, clay abundancy etc.) and how this would affect early diagenesis. The ultimate composition and texture of sediments, however, depends not only on provenance and final depositional environment but also on factors such as tectonic setting, climate, and transport history.  Important changes in depositional composition and texture through time and space may take place even within the same depositional facies in response to variations in such factors.  In the course we will review these controlling processes as well as discuss important advances in analytical techniques that provide a fast, inexpensive means for characterizing depositional compositional and textural variability through time and space.

Post-Depositional Processes

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 will consider two broad groups of models associated with sandstone reservoir quality prediction.  These first of these has to do with predicting the spatial distribution of compositional and textural characteristics of sands.  This model group considers factors associated with provenance, tectonic setting, transport history, and the depositional system.  The second group of models encompasses 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 also are an important component of this group.  In the course we will review some of the leading approaches that have been developed for both groups of models.



The International Association of Sedimentologists (IAS) has kindly confirmed the support to the school which will be provided in form of travel grants to IAS student members. Applications for the grant have to be submitted through the IAS website (

The deadline for sending your application is therefore postponed to the 25th of May.


Following the numerous enquiries we received during the last week, we think it’s opportune to share an update on the organization of the school. Before going into detail, we would also like to inform you about the 10 days extension of the deadline for submitting your application which has to be sent by no later than the 25th of May. Many interested people have asked on the chance to access to the travel support grant provided by the International Association of Sedimentologists (IAS). We’ll receive an answer from the board of the association following a meeting happening next week. IAS members needing the grant to travel would have – in case of approval from the IAS – the chance to prepare the application and submit it in time.


We have also received enquiries on the organization of the school and on the microscope workshop. Further information below.


  • The opening ceremony of the school will be Sunday the 26th of August at 5pm at the GeoZentrum Nordbayern where an icebreaker party will be offered.


  • Lectures/practice will start at 9am and finish at 5pm with a lunch break between 12.30 and 13.30. A poster session accompanied by some snacks and Bavarian beer will follow until 18.30. The idea is to give students the chance to prepare posters focusing on their research, possibly showing the most critical aspects of technical approach used and/or problematic interpretation, and receive advises by the course leader and more experienced researchers.


  • The microscope workshops assume familiarity with optical microscopy and petrographic techniques and are not intended to provide a comprehensive review of sandstone  petrographic methods.  Instead, the focus will be on analytical techniques of critical importance in sandstone petrology that are not commonly taught (e.g., grain coating measurement), are difficult to do (e.g., distinguishing between clay replacement and cement textures), or are often done incorrectly (e.g., porosity determination near grain boundaries and deriving grain size distributions).
