pdf Sequence stratigraphic model of Nepa and Tira Vendian Formations located in the central part of the Nepa Arch (the Nepa-Botuoba anteclise, Sibeian Platform)
Petrofacial and sedimentological core description of Nepa and Tira Formations composition is made for research of sedimentary cover structure. The key sequence stratigraphic surfaces are produced: sequence borders, transgressive borders, and the high sea level surface. In the time interval of Nepa and Tira Formations four sequences of the third order are observed. The system tract characteristics of the identified sequences are given. It’s noticed, that at the top of Vch-1 productive unit a subaerish gap with supralittoral evaporates was identified, that conforms to the geological border between Nepa and Tira geological development stages.

Keywords: Petrofacial and sedimentological core description, sequence stratigraphic model, Vendian, Nepa Formation, Tira Formation, Nepa Arch, Nepa-Botuoba anteclise, Siberian Platform.

pdf  Structure and formation conditions of the Kolganian suite on the south of the Orenburg region
On the basis of 3D seismic data the clinoform structure of the Upper Frasnian – Lower Famenian carbonate-clastic Kolganian suite has been identified. Sediments of this suite have formed series of heterochronous shelves, which were advanced progradationaly toward deep water basin from eroding island land – Orenburg swell. Sea level fluctuation caused changes of terrigenous sedimentation to carbonate sedimentation and vice versa. River systems were developed and deltaic complexes were formed during the Evlanov-Liven and Lower Famenian sea level falls. Deltaic genesis of the Evlanov-Liven (Upper Frasnian) producing sandstones has been identified on the Vakhitov oil field. The Elets (Lower Famenian) complex of deltaic deposits that is considered as perspective for oil exploration was identified.

Keywords: 3D seismic, facies analysis, Kolganian seismic sequence, eroded land, sea level changes, progradation of shelf clinoforms, river deltas.
