WAYS TO IMPROVE SCIENTIFIC AND METHODOLOGICAL SUPPORT OF THE SOLID MINERALS EXPLORATION
The article deals with the problems and directions of development of scientific and methodological support of geological exploration for solid minerals. The need for a comprehensive analysis of the mineral resource base condition, production and consumption of the most important types of mineral raw materials as the most important factor in the planning of exploration and subsoil use in general is shown. The data on the time limits of supplies depletion of certain types of solid minerals for specific developed areas and regions with a quantitative assessment of the deficit requiring immediate reproduction of raw potential are presented. The necessity of assessment of revealing and development possibility of unconventional objects of mineral raw materials is pointed out. In order to eliminate the emerging shortage of exploration areas it is proposed to accelerate the introduction into the stages of regional studies special type of work – prognostic-mineragenic, aimed at the identifying specific local ore prospective areas. There are also proposals on the need to improve the entire prognostic-exploratory complex on the basis of the introduction into exploration practice modern domestic and foreign technologies: aerogeophysical, including unmanned, ground geophysical, geochemical and geological works, some examples of which are reflected in the article. An important place in the paper is also given to processing technologies and geotechnological methods of solid minerals production, designed to ensure the effective development of deposits with poor, complex and persistent ores that make up a significant part of the unallocated subsoil reserve fund.
Keywords: prediction and search, scarce types of mineral raw materials, stages of exploration, prognostic-mineragenic works, modernization of prognostic-exploratory complex, technologies of geological exploration, production and processing of mineral raw materials.

GEOLOGICAL STRUCTURE AND MINERALOGY OF THE MURZIN GRANITE MASSIF ON THE EASTERN FLANK OF THE MIDDLE URALS
The presented materials characterize the features of the deep structure of the Murzinskiy massif, which is part of a polychronous granite batholith with a concentric zonal structure. The confinement of ore deposits to certain intrusive complexes, gold deposits and manifestations is shown to the eastern exo-contact of the Murzinskiy massif. The authors concluded that there is a high metallogenic potential for the manifestation of ore gold in the superintrusive zone of the Murzinskiy massif.
Keywords: geological additional appraisal, Murzinskii massif, granitoid, isotopic data, ore formations.

TYPOCHEMISM OF THE NATIVE GOLD IN THE KINTEREPSKY PLACER FIELDS (EGOR’EVSK ORE-PLACER DISTRICT, NORTH-WESTERN SALAIR)
From the weathering crusts, the products of their local rewashing, alluvial placers of Kinterepsky placer field on the fineness and the content of Hg is allocated 3 basic types of gold: 1 with a fineness of 900 to 1000‰ and Hg concentrations < 1 wt. %; 2 – 830-930‰ and 1-3 wt. % Hg; 3 – 800-900‰ and < 1 wt. % Hg. Copper impurity is found only in gold with a fineness of > 900‰ and is characteristic of Au particles larger than 0,25 mm, which are more common in placers. Based on the chemical composition of the studied gold, its ore sources are likely to belong to the gold-(sulfide)-quartz type.
Keywords: crust of weathering, placer, chemical composition of the gold, morphology of the precipitates of gold, impurity elements in gold, gold mineralization, northwestern Salair.

XENOGENIC CIRCONS IN A WINDY BELT SECTION AS A SIGN OF CRUST’S CONTAMINATION IN PALEOPROTHEROSIS OF SOUTH-EAST OF THE FENNOSKANDINAN SHIELD
In the study of volcanic-sedimentary structures which were formed at the turn of Archaean and Proterozoic, first of all attention is paid to determining the age of volcanic rocks, as the most informative in geodynamic terms. The Windy Belt structure is not an exception, in the context of which two major stages of volcanism are standing out: the first is the Kirich stage and the windy belt stage which is finishing the section of the structure. U-Pb dating of volcanic rocks revealed the participation of crustal matter with an average age of 2.85 billion years in the formation of the Windy Belt section.
Keywords: Windy belt, isotopic dating, contamination, xenogenic zircons.

PROSPECTS FOR SEARCHING DIAMOND TUBES OF EXPLOSION ON DOUBRUSH-NOVOZYBKOVSKY SQUARE
When re-interpreting geophysical fields, in connection with deep geological mapping in the southeast of Belarus, attention was drawn to the presence of isometric magnetic anomalies with a size of slightly more than 1×1 km in area to the north-west of Dobrush. Similar anomalies were also established on the territory of Russia to the west of Novozybkov – to the border of Belarus. In this paper, we consider the parameters and possible prospects of these anomalies at the Dobrush Novozybkovsky area.
Keywords: diamond-bearing tubes, Dobrush-Novozybkovsky area, perspective geophysical areas.

ABLATION AND ACCUMULATION CONDITION OF CHEMICAL ELEMENTS IN THE MOUNTAIN-GLACIAL BASIN AKTRU (MOUNTAIN ALTAY)
Analysis of geochemical data obtained from mountain-glacial basin during the period from 1997 to 2013 shows that content of substance in river waters depends of the presence of an available for interaction substance, the sorption capacity of bottom sediments, conditionally equilibrium concentration of the substance in the same medium, as well as specific rates of dissolution — sedimentation and sorption — desorption under the conditions of the considered natural territorial complex. Basing on the pointed dependence and results of analyzed data of chemical composition of river waters, bottom sediments and soils it is assumed that an additional prospecting for minerals in the area of 12–1 km from the mouth of the r. Aktru within its valley is very perspective. As an additional (applied) purpose of the research could be rate estimation of forming of areas with a high content of chemical elements.
Keywords: ablation and aggradation (accumulation), chemical element, mountain glacial basin Aktru.
