NEW METHODOLOGY OF DEEP SEARCHES OF U AND AU-U OF DEPOSITS IN PALEO RIFTOGENEOUS STRUCTURES
New aspects of the U and Au-U deposits prospecting at Precambrian (Paleo) Riftogeneous structures were considered in several regions (Ukrainian and Aldan shields, Baikal Riphean folding and Hercynian folding in North Kazakhstan). Rift model of U-Au ore formation elaborated for Precambrian shields allows to define the metallogenic aspects of origin, occurance, transformation and breakdown of ancient ore-forming complex Au-U systems. The conditions allowing to inherit long living paleoriftogeneous ore structures in Phanerozoic were unveiled. This was the basis for the new methodology of prospecting U, U- Au and Au deposits, which is the single one for Precambrian shields, Precambrian and Phanerozoic foldings.
Key words: riftogenesis, greenstone belts, Fe formations, comparative metallogeny U and Au.
LODE SOURCES OF SUPER GIANT PLACERS IN THE SOUTH-EAST FLANK OF THE YANA-KOLYMA GOLD BELT
This paper contains the description of granulometric composition of native gold from super giant placer deposits (more than 20 t) in the Central Kolyma areas of the Yana-Kolyma Gold Belt. The author uses the obtained study results as a basis to assess the placer-forming significance of different structural-morphological types of ore bodies. Summarized shares of different lode source types participating in super giant placers formation are calculated (on basis of placer gold production data). According to the calculated results these gold placer deposits have formed from cross-cutting quartz veins, whereas “mineralized dikes” and “mineralized zones” are subordinate.
Key words: gold, placer deposits, northeastern Russia.

THE LOW-SKARN DEPOSIT OF GARNETS (ABRADANT RAW MATERIALS) TYRNAUZ ORB FIELD
Results of researching pyroxene-garnet skarns, from the Low-skarn deposit, located at the Tyrnauz orb field are presented. Using laboratory and technological tests was found a possibility to extract a garnet concentrate from skarns of the deposit. The concentrate will be suitable to exploit as abradant raw material. A positive grade of industrial value of the Low-skarn deposit was defined with technical and economic estimations, also was substantiated an expediency to carry out the further research operations. The deposit could be of interest for industrial ompanies from the European part of Russian Federation, which are exploit abradant raw materials.
Key words: pyroxene-garnet skarns, abradant raw, Tyrnauz orb field, Kabardino-Balkaria.

REGIONAL FORECAST LANDSLIDE HAZARD BASED ON MORPHOMETRIC CRITERIA (AN EXAMPLES OF HA LONG — CAM PHA IN THE NORTH-EAST REGION OF VIETNAM)
Basing on morphometric criteria of relief with the use of modern GIS, the writers made regional forecasting of landslide of the area, by the example of Ha long- Cam pha (the northeast of VN). Research methodology is based on topographical features of the area and field work material. Regional landslide risk assessment based on morphometric criteria for the region of Ha Long – Cam Pha demonstrated their high reliability and can be recommended for use in the development of plans for the integrated development of the territory. In particular, it was found that the highest risk of landslides have slopes composed of sedimentary rocks eluvium Carboniferous-Permian and Triassic age.
Key words: landslide, regional forecast landslide hazard, seismic effects on the landslide.

MONITORING PROBLEMS ON FIELDS OF UNDERGROUND WATERS
The poorly known causes and mechanisms of transformation of groundwater properties in carbonate rocks during water withdrawal are studied. Numerous groundwater deposits in the central part of RF (Moscow, Kaluga, and Smolensk provinces) are used to study the spatial and temporal features of the extent of transformation of the properties and composition of subsurface hydrosphere. The causes and mechanisms of an increase in the concentrations of stable strontium (Sr2+) in groundwater are studied. A system of complex monitoring, including different scientific–methodological approaches, is used.
Key words: ground water, monitoring, antropogeneous factors, withdrawal, hydrodynamics factors, hydrogeochemical type of water.

MORFOSTRUKTURNOGO’S FEATURES OF STRUCTURE OF WASTE OF ENRICHMENT KOLCHEDANNYKH OF ORES OF SOUTH URAL
Current tailings of the the South Urals sulphide polymetallic ores enrichment differ in granular composition, morphology and mineral grains dimensions, phase composition that result from the ores’ origin geological and technological factors. The data obtained allow to offer a rational scheme of tailings and waste products recycling and to forecast the main technological parameters of processing.
Key words: tailings, sulphide polymetallic ores, morphostructural composition.

URANIUM INTERESTS OF THE RUSSIAN STATE PROSPECTING UNIVERSITY
An estimate is given of the crisis uranium situation in Russia. Volumes of geological exploration for uranium in Russia do not meet the needs of the nuclear industry. Many years of MGRI preparing the staff on the geology of uranium and industrial development of uranium fields. Created potential of higher school in need of development. It should reform the relationship geological organizations, the nuclear industry and the higher school. Increased importance of foreign economic training for the needs of the world’s resources. Proposed recommendation.
