Every carbonate rock has experienced some sort of diagenetic alteration – otherwise it would not be a solid rock. Whereas most modern carbonate deposits are composed of metastable phases such aragonite and high-Mg-calcite, their fossil counterparts are composed mostly of low-Mg-calcite and/or dolomite. This mineralogical change is one of the results of the diagenetic alteration. Especially shallow-water carbonates are typically lithified very early after their deposition, but might have experienced later diagenetic alteration during burial such as chemical and mechanical compaction, dissolution, recrystallization, or dolomitization. Simply phrased, early diagenesis turns a sediment into a rock, late diagenesis alters the rock. Many of the diagenetic processes can be reconstructed based on careful observation of thin sections, and that is the topic of this course. During the 1-day course, different diagenetic environments will be introduced in several lectures, followed by a microscopic exercise. Thin sections from very different time slices as well as depositional and diagenetic environments will be discussed, and their sequence of diagenetic processes will be reconstructed. A special lecture and exercise deal with the comparatively poorly studied “marine-burial diagenesis”.

Ichnology is a science branch joining sedimentary geology and paleobiology through the study of trace fossils (ichnofossils). Since reaching high popularity in 1970s, after key studies of the late Adolph Seilacher on the ichnofacies concept, ichnology has continued (especially in recent years) to improve tools for interpretation of trace fossils. During Day 1, the short course participants will first become familiar with the basic terminology that is necessary for further communication; afterwards, the present understanding of the concepts of ichnofacies and ichnofabric analysis will be explained and their application demonstrated on sedimentologically useful examples. During Day 2, the course will focus on recognizing and interpreting sedimentary rock outcrops on field photos from selected excursion localities (ICHNIA congress and IIW, IBW and WIT workshops). The short course is intended for all geologists and students of geology working on sedimentary rock outcrops, cores or collected samples.
CANCELLED SC3: Applied Biostratigraphy – registration till June 1 1 day, June 18, 10:00–17:00 CEST (UTC + 2), live virtual course, minimal number of participants: 10; Course leaders: Mike Bidgood (GSS Geoscience, UK), Mike Simmons (Halliburton, UK)

Biostratigraphy (here used to mean the applied study of fossils) forms a natural companion to sedimentology and sequence stratigraphy. Although a highly specialist discipline, it is useful for all sedimentary geologists to understand how biostratigraphy can help can gain insight into, for example, correlation and understanding of depositional environment. Therefore, rather than focus on the fossils themselves, attendees of this one-day course will learn, through a series of practical exercises, using real data, how biostratigraphy assists in: (1) correlation at a variety of scales, (2) determination of palaeoenvironments and palaeo-water depth, and (3) the recognition of depositional sequences and systems tracts. The examples are drawn from carbonate, clastic and mixed depositional environments and from a variety of geological ages. By the end of the course, participants should be able to make a preliminary basic assessment of any biostratigraphic data they encounter, ask the right questions of biostratigrapher colleagues to help them in their work and understand how biostratigraphy can play a role in their research, yet appreciating potential limitations.
This Short will be recorded and recording will be available to registered participants for 24 hours to watch.

Over the last few decades, the use of rock magnetic methods in Earth Sciences has expanded dramatically. Due to the sensitivity of the state-of-the-art instruments, the rock magnetic measurements are nowadays applicable to virtually any rock type, including those showing magnetism so weak that they are commonly considered as non-magnetic. The benefits of rock magnetic methods include high sensitivity, rapidity, ease of sample preparation, non- destructiveness, the ability to sense grain-size variation. The objective of this course is to provide an overview of rock magnetic methods commonly used in sedimentological research. The course will consist of five blocks covering the following topics: (1) introduction to rock magnetism and the significance of magnetic proxy parameters; (2) magnetic fabric of sediments and its application to decipher flow direction, degree of vertical compaction and deformation; (3) rock magnetic methods applied to aeolian sediments and loess/paleosol deposits; (4) magnetic geochronology studied by polarity-reversal magnetostratigraphy; (5) magnetic cyclostratigraphy as studied by astronomically-forced variations on rock magnetic parameters. The course will be concluded by a practical demonstration of measurements derived from the case studies.
