Organisation and examination

Teaching in the first semester, review in January

Schedule

Schedule online

Units courses prerequisite and corequisite

Prerequisite or corequisite units are presented within each program

Learning unit contents

Study of basic geochemical concepts requested for the interpretation of the geochemical signature of marine sediment records. Examples from literature and from personal proposals.
The cursus is divided in five parts:
- introduction; - diagenetic processes; - interstitial waters; - cycle of metallic elements; - paleoceanographical tracers

Learning outcomes of the learning unit

Study of chemical processes leading to formation of sedimentary rocks. Analyses of physical and chemical modifications through early diagenesis. Influence of kinetics and bacterial activity.

For more information see the introduction page on MyULiege. 

Prerequisite knowledge and skills

Basic knowledge of mineral chemistry and thermodynamic.

Planned learning activities and teaching methods

Analyses and interpretation of geochemical signatures of marine sediments. Treatment and interpretation of geochemical datasets. Use of excel-like software. A personal computer is requested.

Mode of delivery (face to face, distance learning, hybrid learning)

Blended learning


Further information:

Theory 7 lectures x 2h and practise work 3 x 4h. Lectures and supports are both in English. 

Course will be given face-to-face during the first semester. Recorded lectures are available on MyULiege at any time for the students 

The practical works will be given on hydrid mode. 

Some exercices and data treatments will be done in class under the supervision of the assistant. The participation to those practise works is mandatory

Other practical works (n=3) will be done at home. 

1. Reading of imposed articles. The written exam will be based on those articles. 

2.Reading of a second imposed article. Personal synthesis under the form of several slides to prepare. Presentation and collective synthesis during the next course. 

3. Selection of a paleoceanograpghical geochemical tracer. Synthesis in 5 sllides and presentation in 5 minutes: proxy definition; site description; analytical methods; main results & interpretation; points to underline. 

More information on the summary table given on the introduction page on MyULiege. 

Course materials and recommended or required readings

A English syllabus is available. Slides are also in English.
