Possible Changes of the Geomagnetic Field Intention in Titonian – Berrassian and Campanian – Maastrichtian

By the results of exploration of Titonian – Berriassian sections of Mountain Crimea and Campanian – Maastrichtian sections of west of the Middle Asia, Volga region and Crimea it became possible to reconstruct the special aspects of the geomagnetic field paleointensity changes. There were received the average scale of variations, that rise at the end of geological periods. It should be noted that at the end of Jurassic the average amplitude of geomagnetic field variations was lower than at the end of Cretaceous.

The Structure Features of Geochemical Field of Snow Cover in the City of Saratov

Researches of snow cover in the city of Saratov. The chemical composition of the melt water and the insoluble residue. Based on the data conclusions about the ecological state of the snow cover.

Recent Studies of Geodynamics Along Nile Delta (Northern Part of Egypt)

The Nile Delta occupies the extreme northern part of the Nile Valley in Egypt. It is located in the tectonically unstable shelf of the northern Africa and Mediterranean or the mobile belt which is marked by a complex subsurface structural framework. The present study aims to determine the recent crystal movement parameters along the Nile Delta using the Global Positioning System (GPS) measurements. To achieve this mission, a GPS network consisting of thirteen geodetic stations has been established along the Nile Delta area.

On the Prospects and Geo-ecological Consequences of Development of Deposits of Potassium Salts in the Saratov Region

The analysis of data on geo-ecological problems of development of potash deposits. The basic group of negative processes that arise in the process of developing the potash deposits. The main directions of research within geoekologicheskih promising areas in the Saratov region.

The Santonian – Campanian Rock Boundary Interval within the Zhirnovsk Uplift (Volgograd Region)

A lithologically continuous Santonian and Campanian rock section has been examined; the character of rock interrelations has been determined as the one common to the junction area of the northern part of the Don-Medveditsa and the southern termination of the Rtishchevo‑Balanda swells and the Karamysh depression.

Transitory Level of Modular Organization in the Late Cretaceous Hexactinellids (Porifera)

The regularly arranged openings acting as additional oscula – subos­cula – in the skeletal structures of numerous hexactinellids made the basis for recognizing a transient level in those sponge organization: a transition between the unitary and the colonial forms. Unitary, autono­mous and colonial sublevels have been recognized in the transition structures. The morphological diversity of the Late Cretaceous transi­tions was called forth by manifestations of mosaic morphogenesis in the representatives of the Lychniscosa and Hexactinosa orders.

Geo-environmental Assessment of Soil Condition in the Zone of Influence Guselskogo Landfill Solid Waste of the City of Saratov

Investigations of soil in the affected area landfill solid waste. Investigated grain size, magnetic susceptibility, acid-base indicator, redox potential, the content of humus in the soil. On the basis of the data obtained in preliminary conclusions about the state of geo-environmental soil cover.

Qualitative Evaluation of Phase State Hydrocarbon Compounds and Geotermobaričeskie Conditions of Neftegazonakopleniâ Medium-verhnedevonskogo Company in the South-western Part of Buzulukskoj Basin (Sartovskaâ Part)

Statistical analysis of the data shows a significant correlation between the magnitude of the curves (GF) and the density (ρ) of hydrocarbon mixtures in Orenburg, Saratov and parts of the Buzulukskoj basin. Gas distribution in nature and depth of the medium verhnedevonskogo by three zones with substantially different phase features (values of the curves) and formation of hydrocarbon systems: I – South (the pre­dominance of gas-condensate deposits); II – Central (oil and gas, and gazoneftânye deposits); III – North (the predominance of oil deposits).

The History of the Study Sea Urchins from the Upper Cretaceous of the Volga Region

In the course of this work we cast the light on the state of research of the Late Cretaceous sea urchins in the Volga region as well as the development of ideas about their distribution in the rocks of the Upper Cretaceous in the region. Resources used in the research include studies about this group of invertebrates since the beginning of the XIX century up to the present day. It was estab­lished that the vast majority of publications consist of fragmentary information containing mentions of echinoderm remnants findings.

Terminal Permian Ichthyofauna from the Vicinity of Viazniki Town, Vladimir Province

The Upper Permian ichthyofauna from Vyazniki, Vladimir Region, has been analyzed. The rocks hosting fossil fish bones have been determined to belong to the terminal Permian ichthyofauna subzone Toyemia blumentalis-Gnathorhiza otschevi-Mutovinia sennikovi. An assumption is advanced that upwards in the section replacement of the fish complexes takes place, with some of the representatives pervading into the Triassic. Description of the actinopterygian Mutovinia sennikovi A. Minich has been complemented on the basis of the new unique materials from the Sokovka location
