Abstract

Authigenic carbonates are crystallized in subaquatic and subaerial settings at various stages of sedimentary rock formation, and are often found in both ancient and modern deposits. The explanation of their genesis may be problematic. However, in most cases the study of stable isotopes makes it possible to reconstruct the authigenic carbonates crystallization mechanism. The fact of the frequent genetic association of authigenic carbonates with hydrocarbons determines the importance of the development of methods for the reliable identification of their genesis.
