Abstract
The article provides the review of the 155-year history of the finds of conularians near villages Kamyshla and Baitugan of the Samara region from the Early Kazanian deposits as well as their descriptions. These findings were previously attributed to one species Conularia hollebeni Geinitz, 1853, now they are served as a basis for the distinguish of two new species - Paraconularia kazanensis Weldon and Shi, 2003 and P. larae Sendino, data on the latter species has not yet published. For verification of a species diversity of conularians of the considered region, it is offered to make the detailed description of the best remained fossils of the modern collecting and then to reconsider all existing materials on this basis.

Abstract
The paper considers the data, concerning the studying of the pyritized shell Nummulites sp. from the nummulite limestones of simferopolskaya formation (Eocene), referred to the nummulite zones Nummulites nemkovi, N. distans и N. polygyratus. The pyrites of two generations are discovered. The first one is the earliest diagenetic framboidal pyrite, connected with the crystallization of the amorphous iron sulfides, and the second one is an idiomorphic pyrite, which forms the aggregates in a form of crystals. Aggregates of the crystalloid pyrite obviously formed on the base of the pyrite framboids and represent the latest products of their recrystallization and recut. The detailed description of the framboidal formations is given. Among them the two compositional types are distinguished. Framboids are represented by the spherical and oval obj ects by size from 1,25 to 15,7 microns. They are built up with pyrite crystals, being from 0,26 to 1,08 microns in size. The only one nummulite shell, containing the pyrite framboids, which has been discovered up to the present time, can justify the ultimately rareness of the suitable for the framboids formation local centers of the reduction conditions. The obtained new data can be helpful for the solving of the question about the dependence of the crystallographic modifications of the framboids on the environment and about the criteria of the definition of the biogenetic nature of the framboidal structures.

Abstract
The paper introduces for the first time the data on the structure and composition of coal-bearing sediments in Ulziit tectonic-sedimentary basin’s margin based on the authors analysis of the core material and borehole geophysical data. The presence of the numerous stereotyped Mesozoic depressions in Mongolia and China related to the intercontinental rift basins defines an actuality of this paper. The authors stress the specific contrast relations of the defined lithogenetic associations. Results by the set of geological and geophysical data correlation analysis illustrate the possibility of local marking horizons definition in the continental sediments of the complexly interlaced strata that has a practical interest for the geological mapping and exploration of the mineral resources in the similar sedimentary basins of Central Asia.

Abstract
It has been established that the North Bureya metallogenic zone is one of the most productive for the mining and alluvial gold in the Priamurskaya province. The total production of ore gold (97 ton) and alluvial gold (160 ton) within the zone was 26,5% of the total gold production in the province. Within North-Bureya metallogenic zone the six ore-placer nodes are allocated - Burindinsky, Umlekansky, Yasnensky, Oktyabrsky, Adamihinsky and Sohatiny. Besides that, the four nodes (Ulunginsky, Tygdinsky, Magdagachinsky and Igaksky) constitute Gonzhinsky ore-placer district. For their productivity ore-placer nodes are divided into the high (more than 50 ton of gold produced), medium (10-50 t) and low (less than 10 t) productive. The estimation of the nodes prospects for the ore and placer gold is given.
GEOPHYSICAL METHODS OF PROSPECTING AND EXPLORATION

Abstract
Continuous non-destructive, non-contact, high-resolution thermal profiling of a set of the rock thermal properties has been performed for the first time in the geological and geophysical practice on all full-size core samples from two wells drilled in Permian-carboniferous deposits heavy oil reservoir of the Usinsk field with a total amount of studied core samples about 3 000. The representative data on thermal conductivity, volumetric heat capacity, thermal anisotropy coefficient of rocks and their mineral matrix were obtained. The data are necessary for the hydrodynamic modeling of the heat and mass transfer processes in reservoirs at the thermal methods of the enhanced oil recovery. The experimental data demonstrated essential variations of the thermal properties along the wells at a scale of 0,005 up to dozens of meters that provided new possibilities for the detailed analysis of the reservoir heterogeneity within a frame of the additional study of the oil field geological structure. It is shown that the results of the high-resolution thermal profiling allow to detail porosity variations and to define more accurately depth intervals with variations of rock mineralogical composition.

Abstract
The change of the paradigm in the applied geomagnetism due to experimental effects, discovered in the Earth’s atmosphere by Van Vleuten, Benkova, Chetaev, and the observations during the two international geophysical years: 1933 and 1957/58 as well as by the world-wide magnetic survey in 1964/65, was substantiated and confirmed. The paradigm (introduced by Gauss) of the potential magnetic field is noted to require the correction due to the occurrence of hydromagnetic effects in the observed main geomagnetic field and its variations. Such effects cannot be described by classical Maxwell’s equations. The minor correction of the effects in question is needed at the expense of the introduction of spherical (toroidal) electric currents and non-force electromagnetic fields which differential operators differ from those commonly accepted that are used in Maxwell’s equations. The use of the solenoidal feature of the magnetic field, which is valid everywhere on the Earth, makes possible to identically introduce the definitions of non-force and force magnetic fields, to write down the original electromagnetic equations and on their basis to formulate a self-sustained theory of the applied geomagnetism. Also, it will aliow one to interpret the observed data with allowance for hydromagnetic effects as well as to construct sources of the Earth’s main geomagnetic field and sources of calm solar-daily variations.

Abstract
The necessity of the changes in the coordinates of the reforming of the property in the natural resource field in the direction of the socialization of the property is justified. The author’s definition of this category is given as an improvement of the satisfaction of the needs of the society, both at the enterprise - employees, managers, property owners, and outside the enterprise - consumers of the goods and services, the population of the territories where the business is and the whole country, and as well the involvement of all stakeholders in this process. The barriers are identified in this way, and the technologies to overcome them are considered, considering the international experience and modern geopolitical realities.
FROM THE HISTORY OF SCIENCE

Abstract
Valeriyan (Valerian) Alexandrovich Kipriyanov (1818-1889) is one of the first national paleontologists. He published articles with descriptions and illustrations of the examined by him the remains of Chondrichthyes and Osteichthyes from the Upper Crelaceous of Kurskaya and Orlovskaya provinces. He became an author of four monographies about Jurassic and Cretaceous reptiles. His scientific biography has not been published up to the present moment despite his considerable scientific achievements. His biographic data was restricted by two issues [5, 9], the texts of which in many ways repeated each other. This article represents new facts of V.A. Kipriyanov biography, information about his collections. The full bibliography of his paleontological works is given in References.

Composition and structure of upper Jurassic black shales from the Moscow region considering new data
75-79 497
Abstract
For the first time the sections of the southeast of Moscow and adjacent areas of the Moscow region, which contain the Lower Volgian and Oxfordian black shales, were studied in detail and described. The existence there of the autochthonous (not redeposited) Lower Volgian deposits was not recognized until recently and studied shales traditionally were referred to as the Middle Volgian substage in the past. The paper gives a detailed description to the shales of both levels and, for the first time, analytical data showing relatively high contents of the organic carbon like their analogs in the Kostroma region and elevated concentrations, often significant, of a number of elements such as V, P, Ni, Mo, Cr, Cu, Pb, As, S, Fe, Zn. The accumulation of the shales is discovered to depend on a paleorelief and the depth of the pool, and they are confined to the pre-Jurassic structural hollows, while in the shallow elevated areas there are low-thickness condensed sections with the complete absence of the shales and the presence of almost solely phosphate interlayers.
