|The structure of the Taryn thrust zone of the eastern side of the Tompon depression of the Pre-Verkhoyansk marginal trough|
|This article examines one of the poorly-studied territories of the Pre-Verkhoyansk regional trough, the Tompon depression, where the seismic surveys carried out by JSC Yakutskgeofizika revealed the definition of two zones of the Kitschan-Tomporuk and Taryn thrust hidden under Neogene-Quaternary strata. The authors supplemented previously performed constructions and obtained new data useful for a wide range of researchers. The Kitchan-Tomporuk and Taryn thrust zones are considered, the manifestation of Kimmerian tectogenesis are studied on the example of the Taryn thrust zone. The Kimmerids belong to one of the main epochs of tectogenesis in terms of the formation of oil and gas traps of the Pre-Verkhoyansk marginal trough, the Verkhoyan-Kolyma folded region, and the Arctic shelf. The structures not affected by Cenozoic folding are of primary importance. Among the thrust-type structures, the most promising are the thrusts and ramps. The Taryn thrust is one of the promising objects in the search for hydrocarbon accumulations. In its structure there are thrust plates that do not go out to the erosion section.
Keywords: Kimmerian tectogenesis, promising object for the search for hydrocarbon accumulation, Taryn thrust zone, Tompon depression, Pre-Verkhoyansk marginal trough, south-east of Yakutia.

|Results of seismical research of the North-Eastern Yakutia|
|The data on our work method, the volumes carried out and the results obtained in the period 1976-1992 are given using general depth point seismic survey in the Zyryansk, Tomponsky depressions, the Tastakh trough of the North-Eastern Yakutia. Authors compared our results with data concerning the adjacent shelf of the Laptev Sea. It is shown that the synchronous sedimentary sequences can be distinguished on the temporal sections and interpreted as depressions, deflections, and shelves. Field seismic materials are characterized by good quality suitable for processing.
Keywords: general depth point seismic survey, Tastakh trough, Zyryansk, Tomponsky depressions, North-Eastern Yakutia.

|Newest forecast and data updating of Vilyuy Syneclise (Eastern Siberia) petroleum objects|
|The research area is the one of the most studied on the Siberian platform. However, the predominant amount of geological and geophysical data had been obtained in the 60-70`s of the last century at a relatively low methodological and technological levels. Until recently, the main focus of research here were almost exclusively on the Mesozoic and Permian sequences, which form the upper part of the sedimentary cover to a depth of 2-6 km. Several gas-condensate fields were discovered, numerous oil shows were identified. The effectiveness of geological exploration of the past years is assessed; and the necessity to return to many of these studied areas again is substantiated taking into account new insights into their structure and using modern technologies of oil and gas exploration. In addition, for the first time the issue of the feasibility study of Vilyuy area and additional investigation was comprehensively considered, where the possible discovery of new hydrocarbon accumulations, mainly oil, is expected.
Keywords: petroleum objects, hydrocarbons accumulation, Mesozoic and Permian sequences, Vilyuy Syneclise, Eastern Siberia.
