The epibiosis’s features of the Oxfordian oysters Gryphaea dilatata Sowerby from Nizhnie MnevniH (Moscow) are first studied. The oysters used the attachment as a way to root to the substrate. The significant variety of the contact pads is revealed, indicating the deposition of the oysters on different hard objects, supporting the hold and stability of the epibiont. The objects of the attachment (contact pads) were lithosubstrate and biosubstrate approximately in equal proportions. The oysters were poor specialized in the lithosubstrate choice. The objects of the attachments within the biosubstrate were only scalped ammonites (78,5%) and bivalves (21,5%). Cases of the attachments of the Gryphaea oysters to the concrete species of the fossils are not revealed. The general analysis shows, that the oysters preferred to root both at elevated sites (44,4%) and at the depressions of the substrate (37 %), however did not like the flat surfaces (18,6%). The largest scars were formed in cases of the attachment to the elevated sites. The research of the contact pads of the Gryphaea oysters revealed more obvious picture of the composition of the Oxfordian biota at this location. The presence of the bivalves Oxytoma, Pholadomya and Trigonia is distinguished, but their remains are not existed. The twenty four studied specimens are illustrated.

The usefulness of automated lineament analysis for the exploration and engineering geology is shown on concrete examples. The hydrocarbon deposits are established to be formed in the areas of the high density of the transverse local lineaments (to a lesser extent - the longitudinal ones) with respect to the morphological structures. Obliquely cutting lineaments have no correlation with deposits of hydrocarbons. The migration of fractured groundwater and the active development of landslides occur in areas of high density of local lineaments oriented across the river valleys and mountain ranges. The migration and concentration of alluvial groundwater occurs in the areas of regional thickening (extended) lineaments. Earthquakes are characterized by the patterns of predictive cyclical changes in systems of lineaments expressed in the increase in the degree of manifestation of transverse lineaments, regular change of the ratio of different lineaments strike and in change of the characteristics of the field lines stretch out and rose diagrams in preparation of the earthquake and after it happens. Digital elevation models reveal morphological structural lineaments, and space images - landscape lineaments that represent the disjunctive structure of the Earth’s crust best of all.

The works is made on the base of the materials collected during two field phases (2013-2014) in the territory of the R-41-XX, XXI sheet (Amderma area). Visean-Serpuhovian bathyal sediments of Pai-Khoi Shale Belt are represented by Kara formation. In contrast to the underlying and overlying predominantly clayey-siliceous sediments, it is composed of carbonate rocks. This study is focused on composition and origin of the carbonate sediments of the Kara formation in North East Pai-Khoi and is based on the analysis of cyclic sedimentary rock associations - cyclothems. The upper part of the formation section encloses two cyclothem types: fourth type is a sedimentation sequence, which is adequate to the development cycle of hydrothermal structures («white smokers»); the fifth type is represented by so-caffed seeps or nucleuses of fluid flows leakage on continental margins. The deeper section is formed by the activity of the carbonated turbidites. Finally, the formational model of Kara formation (Mississippian period) of North East Pai-Khoi is constmcted, which is considered to be responsible of the sedimentation sequence.

In the structure of Anrakhai massif of Chu-Ili region (Southern Kazakhstan) metamoiphic formations of high-pressure conditions derivation (under eclogite facies field) were identified; the rocks are represented by eclogites and garnet clinopiroxenites. Investigation of mineral and chemical compositions of melanocratic high-pressure varieties as well as detailed petrographic and geological studies allowed characterizing P-T parameters of the metamorphic rocks formation (P 1,6-2,1 GPa; Г750-840°C), determining presumed protolith composition for them, that represented evidently the fragment of differentiated complex of mafic-ultramafic compositions, located within the continental crust prior metamorphism.

Varieties of quartz at silver occurrence Aid and silver veins of gold-rare metals deposit Ergelyah are studied. New data on the textures of comb quartz and earlier not documented the late coarse-grained quartz is presented; the IR- and X-ray luminescence spectra are analyzed. The transitions in growth process of comb quartz from the nearselvedge small unsplit crystals to wider split parts of the individuals, elongated along the c-axis, and then to transparent heads of crystals is considered. The formation of transparent heads of comb quartz crystals is replaced by crystallization of coarse-grained unsplit faintly smoky quartz, filling the axial parts of veins. The OH (Li) absorption band is typical in the IR-spectmm of comb quartz, which is usual to radiation citrine quartz, and the X-ray luminescence is in the field of 390-415 nm. Later unsplit coarse-grained quartz is characterized by the absence of OH (Li) absorption band in the IR-spectmm, and X-ray luminescence in the field of 530-535 nm.

Dzhagdy-Selemdzinskaya metallogemc zone is shown to be the one of the most productive gold-bearing zones in Priamurskaya province. The placer and ore deposits mined in the area are estimated to be about 350 t of gold, including 293,811 of placer and 57,191 of ore deposits. Thirteen placer ore nodes are allocated within the area (west to east): Dolbyrsky, Unya-Bomsky, Tuksinsky, Dugdinsky, Norsky, Egorsky, Malomyrsky, Verhnestoybinsky, Tokursky, Haiginsky, East-Selemdzinsky, Sophiysky and Kerbinsky. The potential of the mctallogcnic zone is in additional exploration of known gold deposits, search for new deposits and placer deposits, as well as the revaluation of waste dumps of large placers to identify the technological clusters of gold.

The longtime experience of the engineering-geological research of the archaeological sites has leaded to the necessity of regarding them as natural-archeological systems, entering the variety of the natural-technological systems. The use of engineering geology methods in the monuments study allows finding new ways to their preservation. The conception of «natural-archaeological systems» is justified; the differences from the natural-technological systems are illustrated. The structure of systems is considered as well as an interaction of the subsystems, forming them: historical-archeological, geological and biological ones. The characteristic of the stages of formation and functioning of natural-archeological systems is done, such as creation, exploitation, destruction, post-exploitation. The examples of multiple exploitation of the one and the same area for different types of the development are shown.

The features of geological engineering conditions of the territory of the Kirillo-Belozersky museum-preserve are characterized; they are emphasized to be very favorable for the development of cryogenic heaving (due to widely spread clay grounds of different genesis, high humidity of the ground). The results of observations of the depth of seasonal freezing of the grounds, snow depth, and vertical displacements of wall constructions of monuments are analyzed. The value of the depth of freezing inside the “cold” (unheated) monuments is established to significantly exceed the depth of seasonal freezing of the grounds on the exposed surface under the snow. Maximum depth of seasonal freezing in the interior of the “cold” monument is 190 cm. The cryogenic heave is revealed to lead to the seasonal, alternating movements (ripples) of the walls with amplitude up to 24 mm for the winter season. The basic control measures are suggested to eliminate the causes of the development of this process and ensure the stability of structures: the works for planning the territory, creation of drainage systems, changes in temperature regime of the interiors.

The existing relations for definition of the axial load on the rock cutting tool by the parallel or serial mounted throttling valves, do not take into account many different flows of the hydraulic fluid through the valve, and it results in different character of the pressure losses levels related to the power. Because of this, we can not exactly evaluate variations of the axial load on the cutting tools when changing hydraulic parameters of the thrust mechanism. The flow pattern of the hydraulic fluid through the throttling valve and through the pressure shift is defined by the mechanical speed rate of the bore drilling. Flow pattern (laminar or turbulent) is necessary for the definition of the axial pressure on the cutting tool. The power index of the fluid flow through the valve or through the pressure shift is variable value, depending on the flow pattern and mechanical speed of the drilling.

The characteristic of the current state of uranium mining and processing enterprises of Ukraine is shown. The scheme of radiation monitoring of uranium facilities on the basis of instruments and automated radiation monitoring systems of new generation such as radiometer RKS-02 «Cordon»; radiometer RUG-2001; Multi-channel installation «Pulse-1М»; Radiometer RZBA-06; Radon Monitor AlphaGUARD; Complex IRGC-2010Z; autonomous system SkyLINK; gamma monitor GammaTRACER etc. on the basis of mobile automotive lab is described. The system of the preventive measures is presented, including the control of the environment, the protection of workers and the public. The necessity of the establishing of the systematic health surveillance for the prevention of harmful effects on the body by heavy metals and radioactive contamination is grounded. The necessity of the introduction of nature-saving technologies and equipment as the economic responsibility of enterprises and organizations for the environmental pollution is justified.

The mining companies use the gold loans (credits) both to finance gold-mining works, and to hedge the price of a new metal; refineries and enterprises for the production of articles made of gold use the gold credits to manage an exposure to fluctuations in metal prices; commercial banks and portfolio investors - for arbitrage deals and profit. The use of the gold loan scheme in practice is described. The mechanism for the forward sale of gold is shown to be able to be combined with other tools of the credit market and the derivatives market. The role of the central bank in the gold loans is described.

The existing practice of the prices management at foreign enterprises, concerning mineral resources and concentrates, explored at Russian mineral deposits, is considered. The economical consequences of such state of affairs are shown. The authors point, concerning the use of value-added factor in economical evaluation of mineral deposits development, is described.
