Posible Sources of magnetic Anomalies in the South of Precaspian Depression

In connection with Carboniferous, Permian and Triassic rocks, marked by magnetic susceptibility of thousand and dozens of thousands (10-5 SI units) that are located in southern part of Precaspian Depression, samples of these rocks were studied in details, using strongly magnetic samples. The possible effects of anomalous magnetic field were counted on the base of received data.

Reconstruction of the Late Vasyuganian Sedimentation Settings Within the Middle of Group of Fields

The paper deals with the results of complex lithology-facies examination of the UV1 1 layer within the Middle Ob group of fields. It is found that in the area under investigation, the layer was formed in the littoral-marine and shallow-water marine conditions under the effect of waves and currents. A paleogeographic chart has been constructed for the period of the UV1 1 layer generation in the Vasyuganian formation; forecast has been made as to the development of improved reservoir rocks.

Petromagnetic and Thermomagnetic Characteristic of Soils in the Area of ≪Oktyabrskiy≫ Landfill Waste Disposal (Saratov)

Investigations of the physical parameters (magnetic susceptibility, thermal-magnetic effect) and soil texture and soil in the area of the landfill waste disposal. Performed a preliminary assessment of technogenic pollution of soils and soil heavy metals and petroleum products.

Mineral Resources of Khvalynsk District (Saratov Region) in the Health Resort Business Development

Khvalynsk district of Saratov region has unique balneotherapeutic characteristics that led to development of a climate resort network, including alpine skiing resort. However, the resort health effect can be enhanced by the use of local mineral resources: medicinal ground waters and clays.

Unitary Late Cretaceous Hexactinellids (Porifera)

Hexactinellids comprise diverse types of sponges viewed as solitary ones. They used to constitute the basis of sponge communities in the Middle-Late Jurassic and Middle Cretaceous of the European region. The morphological diversity of unitary forms is determined by the skeletal structure with combination of a goblet, a shaft, a false shaft and a system of rhizoids. The goblet wall is peculiar for the highest morphological flexibility, which contributes to substantial habitus changes of the skeleton original morphotypes.

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.
