The void structures of the Veterlin Limestone are cemented by radiaxial fibrous calcite (RFC), which originated by transformation from the original metastable forms of carbonate. In the transmitted light, the cement of the remaining pores is shaped as blade and blocky pseudospar, while under cathodoluminescence it is structured as zonal luminescent scalenohedral calcite (SHC) and dull euhedral calcite (EHC). Nucleation of neomorphic pseudospar on crystals of predate high-Mg cement occurred in conditions of relatively shallow burial. Saddle dolomite is an another product of the burial diagenesis. Seawater values of δ¹⁸O (-1.2 to -4.5 ‰) and δ¹³ C (+1.5 to +4.1 ‰) or marine values influenced by mixing (values with a wider distribution of δ¹³C) are characteristic for isotopic composition of cements in the Veterlin Limestone. The final generation of cements (blocky pseudospar BPS) shows the influence of burial fluids with depletion of δ¹⁸O (-6 to -9 ‰) and preservation of positive values of δ¹³C (marine burial trend). The calculated isotopic temperatures from cements ranged between 18 to 60 °C. Homogenization temperatures of fluid inclusions are not consistent with crystallization temperatures of the burial cement, in accordance to their reequilibration under overheating and neomorphism. The Th of the fluid inclusions (155–350 °C) probably correspond to the peak-temperature conditions of the Veterlin Limestone, which is also partly the same as that obtained from the CAI of conodonts (110–200 °C). The presented diagenetic (cementation) model reflects more really our knowledge about the depositional conditions and also spatial distribution of facies in the Veterlin reef complex.
