Applications of chemostratigraphy to clastic and carbonate depositional systems and unconventional reservoirs5.1 Clastic depositional environmentsThrough case studies, details will be provided on the specific applications of the technique to the correlation of sediments deposited in glacial, continental, shallow marine and deep marine environments5.2. Carbonate environmentsHow can the technique be used in carbonates? What are the unique challenges of using the technique in this system, compared with that of clastics” Various case studies will be presented in this section5.3.
