dc.description.abstractIn the water of the Black Sea, about 80 billion m3 of methane are dissolved, and this condition Persists despite a full cycle of water renewal every 400–2000 years. This indicates a powerful Continuous flow of hydrocarbon gases (HG), and hence the presence of their reservoirs Beneath the seabed (Sozansky, 2013). Vertical migration of HG occurs through tectonic Ruptures (e.g., faults, cracks) that form within weakened zones in the sedimentary cover (Tari Et al., 2000) that act as "chimneys" for upwardly migrating fluids, such as HG, H2S, and CO2 That saturate the bottom sediments (Shnyukov et al., 2013). Gasometric surveys of HG have Enabled to establish promising on the HG tectonic structures represented by Cretaceous- Paleogene anticlines (Tkachenko et al., 1974). One of them is the Golitsyn Uplift, where in 1975 the first gas deposit on the northwestern shelf of the Black Sea was explored. Under the Supervision of G.G. Tkachenko, the basics of the survey were developed in the 1970s at the Department of Physical and Marine Geology and the Research Laboratory of Marine Geology and Geochemistry of Odessa I.I. Mechnikov National University. Based on thousands of Samples of bottom sediments and water, the survey demonstrated the complete absence of any Interrelationship between the distribution of HG and the lithology of the bottom sediments. But it clearly showed that increased concentrations of HG relate to tectonic structures, and This connection enabled the conclusion about the epigenetic deep origin of HG (Tkachenko et Al., 1974).uk
