BIOGEOCHEMICAL METHODS FOR DETECTING BLIND DEPOSITS
The biogeochemical methods are available and one of the most effective tools used to discover blind ores. Analysis of recent data on the biogeochemistry of mineral deposits allows to improve the survey techniques, in particular, by designing a suite of key bio-indicators for various types of mineralization. The radioisotopic indicators (210Po and 210Pb activities, total activity in the ashed plant samples) were studied at the site of the concealed uranium deposit Stolbovoe, where their combined anomalies helped localize the mineralization zone.
Keywords: exploration biogeochemistry, plants, uranium deposits, 210Po, 210Pb, total activity.

ACTIVATED FAULT TECTONICS AND FORMATION OF HYDROCARBON DEPOSITS IN THE SEDIMENTARY-NATURAL BASIN IN THE SOUTH OF THE SIBERIAN PLATFORM
It is argued that deposits in the productive formation of the Precambrian terrigenous complex were formed due to sub-vertical fluid flows from sub-fundamental sources under the influence of fault activations of early northeastern generations, and in the productive carbonate horizons of the Vendian-Cambrian and Lower Cambrian – due to the re-formation of deposits in terrigenous formations under the influence of faults of late north-western generation. At the same time, the deposits were formed in the zones overlapping to faults of earlier generation. This means that in the carbonate reservoirs it is impossible to achieve the advanced development of deposits, and in determining the order of prospecting the terrigenous horizons should be considered as basic or priority. The results of the studies are consistent with the deposits distribution on 35 fields in the south of the Siberian Platform.
Keywords: Nepa-Botuobin anteclise, sedimentary and rock basins, activation, fault systems, HC traps, terrigenous rocks of Precambrian, carbonate rocks of Vendian-Cambrian and Lower Cambrian.

BLOCK OF NICKEL ORE IN THE MORAINE DEPOSITS OF THE DUKUKSKY ORE REGION OF THE KAMCHATKA NICKEL PROVINCE
In the upper reaches of the Khihku river, on the left side, near the riverbed, in the moraine sediments, a block of intensely sulfidized rocks of ultramafic composition of size 0,7 x 1,0 m and weight of about 2 t was found and studied. The amount of sulfides is from 30 to 70 %. The main minerals are pyrrhotite (70–85 %), chalcopyrite (5–15 %) and pentlandite (5–7 %). The average content of ore elements is (in %): nickel – 1,99, copper – 1,83, cobalt – 0,077; precious metals (in g/t): platinum – 0,28, palladium – 0,35, gold – 0,29.
Keywords: the Kamchatka nickel province, nickel, copper, cobalt, platinum group elements.

TECTONIC OF THE PRE-MEZOZOYSKY MEGACOMPLEX OF THE PRIURAL PART WEST SIBERIAN GEOSYNECLISE ON EXAMPLE OF URAI AREA
The technology of constructing the tectonics scheme of the domezozoic megacomplex (consolidated foundation) of the Uray area Priural part West Siberian geosyneclise on the basis of 3D density model of lithosphere upper part to a depth of 80 km is considered. It is shown that specificity of the structure earth’s crust is an important factor for regional geological mapping and regional-area prediction, especially when searching for hydrocarbons in the lower sediments and new objects.
Keywords: Earth’s crust, upper part of the lithosphere, deep structure, tectonics scheme, gas, oil.

ASSESSMENT OF THE GEODYNAMIC SITUATION ACCORDING TO THE HYDROGEODEFORMATION (HGD) FIELD MONITORING DATA
The developed recommendations on the increase of geodynamic information content of the monitoring of the HGD field carried out by the FSBI «Hydrospetzgeologiya» in the seismically dangerous regions of Russia. The issues of aquifer selection are considered, under constant monitoring of the hydrodynamic, hydrochemical and thermodynamic mode of groundwater in each observation well. The necessity of complex monitoring of the HGD field and geophysical fields, in particular of the electromagnetic field, on the created polygons in seismically active regions and the comparative analysis of their results is considered. The results of the assessment of the geodynamic situation with respect to the energy parameters of the HGD field, the cycles of hydrogeodynamic impulses, and the attractors that unite them during the preparation and manifestation of the Kultuksk earthquake, greatly enhance the geodynamic information content of the monitoring of the HGD field.
Keywords: HGD field, seismically dangerous regions of Russia, geophysical field, Kultuksky earthquake, mode of groundwaters, complex monitoring of the HGD field and geophysical fields, in particular of the electromagnetic field.

STEADY AND DIFFICULTALLY BEARED ORES OF GOLD DEPOSITS OF THE FAR EASTERN FEDERAL DISTRICT
Of the gold deposits of the Far Eastern Federal District in recent years, more than half of Russia’s gold is mined. The main production sites in return for depleted placers are ore deposits. Of these, in the first place were worked out deposits with rich and easily enriched ores. For the exploitation of deposits with hard and labor-intensive ores, it is necessary to introduce new modern methods of gold extraction.
Keywords: gold deposits, placers, mining, ore, biohydrometallurgy, autoclave leaching.
