The Possible Scenario for Climate Change on the Egyptian Nile Delta

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.

Physical and Geological Modeling as a Basis of Geological Interpretation of Geophysical Data Complex

The questions need physical and geological modeling in solving inverse problems of geophysics and the notion of a coherent FGM. The key provisions of the agreed methodology seysmogravimetricheskoy FGM, grounded approach to seysmogravimagnetic modeling and provides examples of its implementation

About the Problems and Value Priorities of Educational Baccalaureate System (with Geophysical Area Programs as an Example)

The vital problems of passage to the two-bin system of formation in the Russian higher school are represented. Is proposed within the framework [bakalavriata] to go away from the traditional physicomathematical orientation of the programs of geophysical direction to the side of geological priorities. Some aspects of the realization of this idea based on the example of the program of the course of geophysics are examined

The Anomalous Crust of the Astrakhan Arch

The anomalous characteristics of the Astrakhan Arch crustal structure were revealed during the seismic data interpretation. They indicate plastic deformations of the lower crust at the sites of its fluidization, manifestation of the waveguide and enhanced permeability zone properties in the upper crust in the ways of the fluid flow. The unique Astrakhan gas condensate field, localized in the carbonate platform of the Middle Carboniferous age at a depth of 4.0 – 4.5 km, was formed in the area of HC-containing deep fluid discharge

Colonial Level of Modular Organization in the Late Cretaceous Hexactinellids (Porifera). Genuine Colonies

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.

Использование микробиологических показателей в эколого-почвенном мониторинге города Медногорска

Проведена микробиологическая индикация техногенно нарушенных почв г. Медногорска на основе оценки численности гетеротрофных, железо- и марганецокисляющих бактерий. Установлена взаимосвязь между высоким значением показателя коэффициента магнитности в почвах и повышенным содержанием железоокисляющих бактерий, что свидетельствует о возможности использования данной группы микроорганизмов для мониторинга загрязненных тяжелыми металлами почв

Terrigenous-mineralogic Characteristics of the Bobrikovskian Horizon from the Saratov Trans-Volga Region: Paleogeographical Aspects

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.

Magnetic Structures as Indicators Some Features of Formations of Tithonian-Berriasian Rocks in the Mountain Crimea

Anisotropy of magnetic susceptibility was measured in ~ 1,300 samples from 10 sections of the Tithonian-berriasian of the Central and Eastern Crimea. In consequence of the analysis of magnetic structures were found different degrees of tectonic deformation of rocks and corrected geological structure of explored area

Main Features of the Permian Halogenesis Hydrochemistry in the Caspian Region

In 1960–1980, the Elton and the Gremyachka deposits of potassium salts were discovered within the Permian halogen sequences in the Lower Volga Region, bischofite presence was recorded in the Privolzhskaya monocline, the conditions of halogen-bed formation were defined as those peculiar for typical evaporites. But in 1980-2010, halogenesis hypotheses emerged that denied the principal importance of climatic factor and the dominant role of oceanic waters in the brine composition of the salt-generating basin.

Earth’s Response to Orbital Excitation and Hierarchy of Climatic Events and Rock Cyclites Over the Recent Time

Analysis of the published material has made it possible to show the cyclic variations of the earth’s response to be practically coincident with the orbit parameter fluctuations, when the time lag of 5–6 thousand years is considered. In the earth’s response, however, periodicity changes are more complicated due to resonance phenomena and to numerous feedbacks in the system responsible for additional period occurrences.
