Module 4. Lithologies and Microfacies

Course Details

The major difference in the way sedimentologists approach carbonates lies in methodology. Unlike siliciclastics most carbonate cores are devoid of sedimentary structures. In carbonates thin-sections must be created to create microfacies and these are interpreted for environments of deposition, diagenesis and pore types.

In recent years a great deal of work has been done on microbial carbonates. This module not only introduces participants to the popular classification schemes of Folk and Dunham but also covers classification schemes for microbialites.

After spending an hour on lectures the last 2 hours of this module will be spent on exercises on thin-sections and core. Whether you will be doing thin-section or core descriptions yourself, or you would like to be able to gauge the quality of the work done by a consultant for you, this module will serve you well.


• Geologists
• Geophysicists who wish to better understand carbonate seismology and seismic stratigraphy
• Petrophysicists
• Engineers who wish to develop a better understanding of the factors that control distribution, reservoir connectivity and compartmentalization in carbonate reservoirs

• Graduate Students (Masters or Doctorate) who wish to develop a better understanding of the petroleum industry and the importance of carbonate reservoirs


The course assumes no prior knowledge of carbonates therefore we also encourage non-geoscientists and graduate-students to enroll.
