|The hydrocarbons composition of oils and bitumoids of the tectonites of the Saralin trough of Tatar Arch|
|Based on the analysis of distribution of biomarkers in the composition of oils and bitumens of different ages of rocks opposite slopes Saralin trough the presence of two separate entities generated in a reducing environment and marine conditions of sedimentation, but with different content of carbonates in the clay oil-producing strata. It is shown that the hydrocarbons composition has various catagenetic maturity, and the fluids which differ in the degree of thermal transformation, are present on both sides of the trough, in the studied rocks characterized by a fractured texture.
Keywords: hydrocarbon composition, biomarkers, tectonised rocks, Saralin trough, Tatar Arch.

|Hydrocarbon composition of bitumoids from rоскs belonging to Muharmetovsk oil field (South-Tatar arch)|
|Based on the data of component analysis and distribution of geochemical parameters shown the genetic uniformity of the hydrocarbon composition of bitumoids from Devonian rocks and basement of Muharmetovsk oil field. The hydrocarbon was generated by sapropel material associated with clay minerals under reducing diagenetic conditions. Almost identical catagenic maturity of organic matter of these rocks is identified. Comparative analysis of bitumoids biomarkers of sedimentary and metamorphic rocks of the regions with different thermal gradients have shown that the hydrocarbon composition of bitumoids component of Muharmetovsk oil field Devonian strata has not borne the effects of the deep thermal evolution. On the contrary the maturity degree of bitumoids from basement was higher than for the rocks from zones of higher thermal gradient.
Keywords: bitumoid, hydrocarbon composition, biomarker, Devonian, basement, thermal gradient field, Muharmetovsk oil field, South-Tatar arch.

|Hydrocarbon composition of water-soluble organic matter of the Devonian formation waters in the thermal gradient field of Matrosovsky oil field of South-Tatar arch|
|It is shown that the hydrocarbon composition of formation waters from Biysk layer of Matrosovsky oil field of South-Tatar arch include alkanes of normal and isomeric structure. Obtained biomarker factors point to the enrichment of rocks, enclosing the original organic matter, by carbonate minerals, marine depositional environment with moderate salinity and prevalence of photosynthetic bacteria (prokaryotes) above algal eukaryotes in the initial biomass. The water-soluble organic matter of formation waters has a low degree of catagen conversion that was not affected by thermo-gradients fields of rocks from Matrosovsky oil field. In terms of thermal maturity, organic matter is closer to the bitumens of basement than oils of overlying Devonian strata.
Keywords: water-soluble organic matter, hydrocarbon composition, oil, bitumens, biomarkers, Devonian, thermal gradient field, Matrosovsky oil field, South-Tatar arch.

|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.
