Geochemical characteristics of methane from sediments of the underwater high Posolskaya Bank (Lake Baikal)

The component and carbon isotope compositions were studied in the hydrocabon gases from sediments of the underwater high Posolskaya Bank (Lake Baikal). It was established that sediments of this Baikal area contain methane of microbial (C 1 /C 2 >16000; δ 13 C 70 ± 3‰) and thermocatalytic (C 1 /C...
