摘要

Abstract

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 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.
