|Influence of temperature anomalies in the basement weathering crust on the Matrosov oil field (South-Tatar Arch) Devonian biomarkers|
|On the basis of geochemical indicators of Devonian oil Matrosov field (South-Tatar Arch) has been demonstrated the possibility of changing the ratio of higher biomarkers - terpanes (C2718? trisnorgopan and C2717? trisnorgopan) and steranes (?C29 diasterany and ?C29 regular steranes) under the influence of the "anomalous" thermalgradient zones of the weathering crust basement. This fact is evident in the growth of content in oils thermally stable hydrocarbons that promotes the separation of the devonian oil, characterized by a single source of marine origin, but occurring at different levels of the weathering crust basement into two groups.
Keywords: oil, bitumens, biomarkers, Devonian, zone temperature anomalies, basement, Matrosov oil field, South-Tatar Arch.
