Geological-structural investigations on the all area of Windy Belt allowed distinguishing three systems of gentle dipping zones of faults: Kirichinskaya, Tokshinskaya, Bulatovskaya systems and the system of steep faults of different directions of dipping. Gently dipping zones correspond to the stages of compression of Windy Belt with its interaction with boundary structures (Belomorsky Belt and Karelian granite - greenstone region). The system of steep dipping faults formed in the tension environment.

The new data on a composition of the Osipa and the Chaidakh Formations (Upper Triassic) in the Pronchishev Range region has been obtained. Stratigraphic subdivision of the geological succession by complex bio- and lithostratigraphic methods was carried. By results of the carried-out (implemented, done) litofaciesanalysis the studied deposits have been found to represent the uniform regressive sedimentological cycle with the transgressive pack in the basis. Consecutive change of sea-shallow sedimentation conditions by coastal is noted. The comparative analysis of the studied geological succession with basic successions of adjacent areas showed that its structure has the Leno-Olenek type but with moredistinct far-coastal deposits characteristics.

This study reports the occurrence of ooid-stromatolite association (0,5-9 m in thickness) in the Lower Paleozoic sections of the Timan-northern Ural region. Well-preserved different fabrics seen in ancient ooids and stromatolites have previously been interpreted with respect to paleoenvironmental conditions which brought changes in benthic ecosystems. Results from current study suggest that it is possible that the connection of ooids with stromatolites at the time-levels depends on their genetic relationship due to abundance of microbial inhabits during periods of shallow water marine basin regressions. During regression in the result of further paleolandscape differentiation of the bottom the hydrochemical and hydrodynamic regimes of the water reservoir changed. It lead to the quiet-water environments, expansion of microbe and bacterial associations and eutrophy of waters, calcium balance of sea waters fall and reorganization of benthos ecosystems with dominance of mostly euryfacial and euryhaline organisms - Ostracods, gastropods and bivalves. Bulk carbonate values from the Wenlock limestones with ooids average -5,4...-6,4% for S¹³C PDB and 22,9...24,6% for S¹⁸O SNOW. Additionally, a low content of boron 11-30g/t in these limestones also indicates the lowered salinity of waters.

Preconditions of nephrite placers formation in the Central Kunlun mountains and adjacent Tarim depression are considered in Russian literature for the first time: the presence of the primary deposits in metasomatic rocks localized in alpine-type ultramafic and contact-metasomatic rocks; optimal erosional truncation and hydrodynamic trap sites of valuable minerals accumulation; contrast neotectonics; variable climate conditions. The types of nephrite placers have been distinguished: deluvium (boulder stream), morainic valley deposits, proluvial, alluvial of mountain and plain rivers, surface deltas. The examples of typical landscapes of placers are given. Surface delta placers appeared to be modern and ancient buried. The residual placers resources of different genetic types are poor except surface deltas placer. It is justified that the surface deltas (delta fan) deposits in the studied region may contain nephrite placers.

The geological structure, mineralogical and geochemical features of the Amesmessa gold quartz-vein type ore deposit located in In-Uzzal region of Hoggar shield (the Algerian Sahara) are described. The ore-bearing object has Proterozoic age and belongs to the gold - quartz - low-sulfide formation. The basis of its structure and a typical geological setting of the ore veins location are the fault paragenesis that had arisen in a process of the development of a big fault zone during the Ebourneisky tectonic and magmatic cycle. This object belongs to a formation typical for the metallogenic zones of the green belts of the ancient shields and has good prospects of accumulation of the ore resource potential.

Contemporary geocryological conditions of the Urals-Pai-Khoi mountain system has been considered as a result of the repeated and significant changes of the severity of the climatic and geocryological conditions. It has been demonstrated that during all the cryogenic period as well as at nowadays, the formation of the rock temperature, the thickness, the discontinuosity and the structure of the cryogenic strata obeyed and obey the laws of latitude and altitude zoning. The given characteristics of the contemporary cryogenic strata for the segments of Urals and Pai-Khoi illustrate clearly the significant changes in rock temperature (from +3 to -11°C), in thickness (from 0 to 1000 m), discontinuities and structure of the cryogenic strata at the increase both in latitude and in altitude of the area.

The article considers the results of integrated engineering geological studies of Proterozoic sandstones at the construction site near the town of Udokan. The «Standard Statistics» and «Cluster Analysis» programs have been applied by processing the data on density, strength and water resistance of the soils obtained during the research. The samples have been examined for water absorption and longitudinal seismic wave velocity, the structural and textural characteristics of rocks in petrographic thin sections have been studied for the first time. On the basis of complex data, conclusions about the strength factors of the studied objects have been drawn out.

The joint change variations of magnetotelluric field of the Earth and un-tidal variations of gravity, registered on the territory of Bishkek Geodynamic Polygon, are considered. There is a clear relationship of these variations. Obviously, a joint analysis of the variations of magnetotelluric field and gravity gives a new possibility to study the deep structure and dynamics of geo-medium.

In connection with the solution of actual environmental problems of limiting the migration of hazardous contaminants in groundwater aquifers, the appropriateness of vertical slot drains instead of wells is considered. Migration of contaminants is limited by the construction of interceptor drains and pumping through them the underground water passing through the contaminated area of ??the aquifer. Intercepting drainage system is proposed to be constructed with use of technical means for downhole jetting. The technology of their application is briefly considered. With the use of computing mathematics, the effect of increasing the number of wells in a line of fixed length (density of line) on the hydraulic resistance of linear drainage wells is studied. The extreme convergence of wells is proposed to be replaced by the slot drain, constructed using the means of downhole jetting.

Following the results of authors experimental works on Kovdorsky apatite-shtaffelite deposit and taking into account the results of similar works performed by other researchers on ore deposits of various genetic and industrial types, it has been established that for justification of sampling method of slime of drilling-and-blasting wells at open-cast mining of any ore deposits the five experimental wells for each type of a loop of slime (cone-shaped or extended along the «boring machine - mouth of a well» line) are enough.

In the modem economic conditions, gold is a unique investment instrument because of characteristics, such as the credit riskless and high liquidity, which is particularly important in times of economic and geopolitical tensions. The modern function of gold as object of investment, and also classical and modern instruments for investments into precious metal are considered: bars, coins, derivatives, warrants, unallocated accounts, depository receipts, E-gold, Exchange Traded Funds.

This article discusses the relationship of marketing and recruitment, the process of attracting new staff, the scheme 4P in terms of personnel policy, and the main aspects of creating the image of organizations. The ratings of Russian employers are investigated and analyzed, the technology of management of the enterprise with the use of marketing tools, examples of successful companies in this field of work, staff loyalty as a factor of effective development of the company are investigated.

Baddeleyite has been found in disseminated sulfide ores of the Noril’sk ore field within the pneumatholytic aureoles presented above the sulfide droplets. The baddeleyite occurs as lamellae within ilmenite crystals. It contains «1 wt.% HfO2. This new occurrence of baddeleyite and the pneumatholytic aureole mineral assemblage indicates that fluids exsolved from highly fractionated sulfide meltswere enriched in К, P, Ti, but also contained Zr, REE and Cl, F, H₂O, SO₃. The mineral assemblage of the pneumatholytic aureoles is estimated to form at temperatures around 780-820°С based on the titanomagnetite-ilmenite geothermometry.
