Geological-tectonic interpretation of gravity-magnetic information in development of regional geophysical profiles (for example: the profile «Uvarovo – Svobodniy»)

The article deals with the results of geological interpretation of geophysical data received during traversing («Uvarovo – Svobodny» line, the length is 376 km). Integrated gravitomagnetic installations alongside were applied during the process of interpretation. The new tectonic elements were found, and previously found tectonic elements were confirmed. More accurate information about location of the border separating the mentioned tectonic elements was obtained. 

Kinematics of the Electromagnetic Waves from the Second-type Seismoelectric Effect in Two-layered Earth

Analysis of the traveltime curves of the principal types of the electromagnetic waves from the second-type seismoelectric effect was used to demonstrate the possibility of using the kinematic characteristics of that effect fields for studying aquifer locations. 

Mineralogical and Paleogeothermal Criteria for Predicting Oil and Gas Contents from the Rift Sedimentary Basins

Clay minerals and their parageneses make sensitive indicators of diverse processes involved in transformation of the Valanginian terrigenous rocks in the North Khalmerpayutinskaya field by hot solutions. The latter ones used to form hydrothermal-metasomatic reservoirs and to transport HC. The amounts of mixed-layer bodies and the proportions of swelling (smectite) and non-swelling (chlorite, micaceous) constituent packages make it possible to estimate the trap quality and the probability of HC presence.

Local Stratigraphic Units of the Middle Carboniferous Moscovian Stage from the Volgograd-Saratov Volga Region

Analysis of the published factual materials from the Lower Volga region has made it possible to distinguish and to describe eight local stratigraphic units of the Middle Carboniferous Moscovian stage. Lithologic and paleontologic characteristics of the suites and the subsuites are presented alongside with indications of the stratotype sections in particular wells. In the summary, the local stratigraphic units from the Lower Volga Region are compared with the stratotypes from the Moscow Region. 

About Possible Reflexion of Paleocological Conditions in Petromagnesism of Kallovian - Oxfordian Deposits of Dubki Section (Saratov)

As a result of the complex analysis of petromagnetic, micro- and macrofaunistic data of deposits on the Kallovian – Oxfordian boundary of Dubki section (Saratov), which is one of candidates for a role of a Global Boundary Stratotype Section and Point of Oxfordian boundary (GSSP), it is established significant correlation between magnetic susceptibility variations and changes of an abundance, a specific variety of ostracodes, foraminiferes and ammonites.

Aspects of Modern Higher Education

High school and specifically – professional geological education go through the period of essential structural and profound reformation. The modern state of components of higher professional education has been considered. The ideas about disappearing components of this system and probably the fact that can change them have been stated. 

Unique Steppe Natural Complexes of the Left Bank Volga River in Saratov Region

According to field researches of the Left bank Volga river in Saratov region in article are shortly presented descriptions of two steppe sites which are unique for this strongly agriculturally transformed territory. The inference are made about necessity of special researches around there, because it is the most perspective for search steppe protected areas. 

Stratigraphy of the Baojcian-Bathonian Marine Deposites of the Volga Region

There are unceptainties in the boundaries, extensions and ages of the suites recognized in the recent regional stratigra-phic chart for the Middle Jurassic of the Saratov and Volgograd Volga right-bank Regions. Analyses of the new factual materials acquired from numerous well cores and the data from the outcrops in the stratotype locality at the North Vol-gograg Region make the basis for elaborating the deposite division. Detaled lithologic and paleontologic characteristics, their thicknesses and areals are estimated over Volga right-bank Region. 

Mesozoic-Cenozoic Oversalt Deposits from the Gremyachkinskoye Sylvinite Field

The authors consider compositions of the rocks penetrated with the Well NO 13 in the Gremyachkinskoye sylvinite field, Volgograd Region. Varied complexes of terrigenous, ciliceous and carbonate rocks, alongside with their mixed varieties rhythmically alternate there over the Late Cretaceous, Paleogene, Neogene and Quaternary sections. Reconstructions have been made of their generation settings within marine basins; the basin evolution during that lengthy period used to be associated with periodic manifestations of tectonic events of both, global and regional scales. 

Stratigrafy of Santonian-Campanian Deposits of South-Easten Russian Platform on the Example of Section Separation Near the Village Mezino-Lapshinovka and the Problem of Intrasantonian Boundary in the Saratov Volga Region

The results of interpretation of biostratigraphic separation of santonian-campanian deposits of the Saratov right-bank Volga region, on the example of earlier conducted detailed and complex investigation of separation near the village Mezino-Lapshinovka have been presented. The ideas of realiability of variants of the detailed (on the level of subtages) subdivision of santonian substage in reference to the territory of the Volga right-bank have been given.
