Mineralogical and isotopic analysis of authigenic carbonates from different gas hydrate-bearing seepage structures in the Derugin Basin (Sea of Okhotsk) are presented. The analysis showed the existence of four morphological types of carbonates, with all of them mainly of Mg-calcite.13C values of carbonates generally light owing to the inheritance of carbon from microbial methane. 13C-enriched samples at the VNIIOkeangeologia structure with 13C values of up to +9.3‰ represent carbonate precipitation due to methanogenesis. The calculated equilibrium 18O values of carbonates in general correspond to measured values. |
