The preceding chapters provided information on the diagnostic criteria for ‘depositional microfacies’. This chapter deals with ‘diagenetic microfacies’ that reflects changes during lithification and rock history (Pl. 28). Diagenesis refers to physical, chemical and biological processes. The understanding of these processes and their products has high economic importance, because diagenetic criteria account for many of the petrophysical properties of carbonate rocks and determine their value as reservoir rocks and use in industry. Diagenetic studies require a combination of various methods, including standard optical petrography, cathodoluminescence, SEM observations, stable isotope analyses and rare element composition. The following text concentrates on diagenetic features that can be studied in thin sections. Comprehensive reviews of carbonate diagenesis can be found in textbooks listed under Basics in the reference list at the end of this chapter.
