Terrigenous-mineralogic characteristics of the Bobrikovskian horizon within the Saratov Trans-Volga Region is provided in terms of the Berezovskaya group of rises. The quantitative and the qualitative composition changes of the heavy fraction minerals within the section have been determined. The lack of abrupt, intermittent changes of any material composition characteristics testifies to the section relative continuity. Examination of the mineral composition has provided the basis for specifying terrigenous-mineralogic associations in the Bobrikovskian deposits.

A microbiological indication of anthropogenic disturbed soils from the city Mednogorsk was carried out based on the evaluation of the number of heterotrophic, iron- and manganese-oxidizing bacteria. This study states a relationship between high levels of magnetism in these soil samples and high content of iron-oxidizing bacteria, indicating the possible use of this group of microorganism for monitoring heavy metal contaminated soils.
Tendencies of morphogenesis in the Late Cretaceous modular forms contributed to formations of complexly structured secondary (genuine) colonies. Skeletons of genuine colonial sponges differ not just in numerous and diversely arranged equivalent oscula-carrying modules, but in the presence of the module connecting elements – junctions, as well. Characteristic elements of genuine colony skeletons – ostia – have been recognized between the modules and the junctions.

It is known that climate change has an effect on many Deltas all over the world. Egyptian Nile Delta, one of the most dangerous places which may be suffered from risks of climate change. In the current work, an attempt to study the effect of climate change on the Nile Delta has been discussed.

Complex sedimentologic examination of the JV11 oil-bearing bed has been made within the southeastern part of the Yarsomovskij site. The Upper Jurassic beds within the study area were found to be represented by coastal-continental and coastal-marine facies.

Problem for finding the criteria of belonging the vector fields to the set of electromagnetic fields is formulated. The existence and uniqueness of the solution of this problem are investigated. The desired criteria for the set of alternating electromagnetic fields in the frequency domain in the case of isotropic media are formulated. It is shown that these criteria are shared set of alternating electromagnetic fields in linear isotropic media into two subclasses. Are examples of the fields belonging to these subclasses.

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.

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).

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.
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.

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.

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 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.
