Abstract

Carbonate macrofaunal remains and diagenetic tubes collected from a number of structures in the Central Barents Sea area during the 18th TTR (Training Through Research) cruise were subdivided into three groups according to the results of stable carbon and oxygen isotopes analysis. The first group includes carbonates that were formed from bicarbonate only from surrounding sea waters. The carbonates of the second group were formed during diagenesis with use of mixed sources of bicarbonate. The fourth group includes methane-derived carbonates that were formed as a result of anaerobic oxidation of methane (AOM).
