Abstract

Seep fluids of the underwater coastal slope of Laspi Bay are composed of CH4, N2, O2, He, C2H4, C2H6, 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 light isotopic 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 different appearance of the bacterial build-ups of Laspi Bay with other build-ups of cold seeps is explained by the physical and geographical conditions of their formation.
