New Data on Cold Seeps and Beach Bacterial Structures Study in Laspi Bay (Southern Coast of Crimea)
Journal: Moscow University Geology Bulletin
Year: 2024

Seep fluids of the underwater coastal slope of Laspi Bay are composed of CH4, N2, O2, He, C2H4, C2H6, and C3H8 and are accompanied by aqueous solutions. The formation of beachfront bacterial build-ups occurred due to the processing of hydrocarbon fluids by Archaea and bacteria. Their carbonate cement has a light isotope carbon composition (–20.93; –20.83‰). The structures of beachfront bacterial build-ups have all the signs of genetic relation with carbonates of hydrocarbon seepage. The differen
