Learning objectives
Students will acquire a detailed knowledge and deep understanding of the diagenetic processes and products in carbonate rocks and sandstone and the use of geochemical proxies for solving issues related to rock diagenesis, geochemical proxies, climatology and paleogeography.
The numerous laboratory activities and examples of case studies also from the petroleum industry will provide students with the fundamental knowledge to apply what learned in professional and scientific activities. Through written reports about specific issues and case studies, students will develop skills in communication, critical thinking and problem solving.

DIAGENESIS AND GEOCHEMISTRY OF SEDIMENTARY ROCKS
Fundamental concepts of diagenesis, diagenetic environments, processes and products. Classifications of porosity, differences between siliciclastic and carbonate rock reservoirs. Importance of diagenesis of sedimentary rocks in industry (petroleum and water resources) and academia. Diagenesis of carbonate rocks in marine, meteoric and burial environments: processes of cementation, dissolution, neomorphism, recrystallization, dolomitization, dedolomitization, and silicification. Diagenesis of sandstone and mudstone: cementation by carbonate and clay minerals, compaction, dissolution, authigenic mineral formation. Geochemistry of sedimentary rocks: principle of stable isotope geochemistry. The use of stable Oxygen, Carbon, Hydrogen, Nitrogen, Sulphur isotopes in diagenesis, paleoclimatology and paleoceanography: The use of Sr isotopes and trace elements for the study of sedimentary rocks. Techniques for diagenetic investigations of sedimentary rocks: petrographic analysis, staining, cathodoluminescence, SEM, microprobe EDS and WDS, fluid inclusions, and stable isotopes geochemistry.
