GEOLOGICAL STRUCTURE AND POSITION OF IRON-ORE OBJECTS IN TONODSKAYA AREA
Reviewed the features of the geological structure and tectonics of Tonodskaya area Vitimsky iron ore district. The content of terrigene deposits of the Lower Riphean, their position in the geological section and parameters of the ore bodies of ferruginous quartzites, their geological and geophysical characteristics was characterized as a basis for creating predictive-prospecting model. Based on this model contoured deposits of medvezhevskaya formation (Lower Riphean) – as the most prospective for localization of iron-ore objects in Tonodskaya area.

METHODOLOGY AND SAMPLE ESTIMATES OF INFERRED RESOURCES BASED ON THE GEOCHEMICAL DATA FROM THE SURVEYING AT A SCALE OF 1:200 000
Method of calculation of inferred resources on the basis of geochemical data is based on the same parameters as calculation of commercial reserves, namely: commercial grade, ore block volume, and ore-bearing factor. In original exploration data the above categories are difficult to define due to low number of ore samples and low metal concentrations. That is why they are substituted by relative values quantitatively connected to parameters of commercial mineral deposits. A lower level of an anomalous geochemical field (AGF) is statistically selected from the totality of geochemical samples taken within the quadrangle sheet of 1:200 000 scale. Inferred resources within AGF are estimated by two ways: via standard deviation and communication functions of the element content and the ore block volume. The presented method is illustrated by examples.
Key words: inferred resources, factor of economic concentration, factor of economic ore presence.

GEOLOGICAL STRUCTURE, PETROGRAPHY AND MINERALOGY OF THE QUATZITE DEPOSIT BURAL-SARDAG (EAST SAYAN)
The peculiarity of geological structure of quartzite deposit Bural-Sardag is discussed. It is shown that quartzite of the deposit was formed by hydrothermal transformation of carbonaceous quartzite. Quartz recrystallization and its purification from carbonaceous material took place at the transformation. The zone of carbonaceous quartzite transformation is cut down by the fractures, which has heavy pitch. This structure allows to propose the big probable reserves of the pure quartz on this deposit.
Key words: quartzite, geology, mineralogy, petrography, temperatures of homogenization.

CREATING A PREDICTIVE MATHEMATICAL MODEL LAWS GOVERNING THE DISTRIBUTION OF QUARTZ SAND FOR CONSTRUCTION WORK ON THE TERRITORY OF THE REPUBLIC OF MARI EL
To provide geological services of the Republic of Mari El information on prospective areas and probable resources of sand for construction work was carried out to collect and systematize information on geological passed earlier drill holes, deposits and occurrences of building sand republic. Built predictive mathematical model of patterns of distribution of quartz sand, on the basis of which are highlighted promising areas and inferred resources of sand for construction work.
Key words: mathematical, model, forecast, resources, promising, area, sand, construction, Mari El Republic.

NEW DATA ON CENTRAL-KYZYLKUM GROUP CARBON-GRAINED ORE FORMATION MINERAL RESOURCES
The results of mineralogical and geochemical studies of carboniferous rocks and ores from the Central Kyzylkum region (Uzbekistan) have been reviewed. The phase state, carbonization degree and isotope composition of metal-concentrating carboniferous substance were determined. The genesis of mineralization and role of carboniferous substance in ore formation were discussed.
Key words: Central Kyzylkum, carboniferous ore formations, carboniferous substance, isotope composition of carbon

MAPPING ENERGY-ACTIVE ZONES ON THE DIGITAL GEOPHYSICAL MODELS – ONE OF THE WAYS OF THE DEVELOPMENT OF INDUSTRIAL URANIUM – ORE OBJECTS
The absence of the discoveries of hydrothermal type new uranium layers during the last 30 years testifies about the crisis of new ideas and approaches to the forecast- search works on uranium. Proposed to the attention of specialists specialized technology of working the geophysical and radio-geochemical given with the use digital geophysical models industrial uranium- ore objects in the case of its creative application in the practice of forecast- search works it can contribute to the solution of this problem. Given examples of the practical application of present technology convincingly attest about the possibility of obtaining with its use of fundamentally new geological information about the prospect of the territories being investigated.
Key words: uranium layer, computer technology, geophysical model, ore object.

PROSPECTS OF GRAVIMETRY IN THE STUDY OF DINAMICALLY UNSTABLE GEOLOGICAL OBJECTS
Hydrocarbon deposits, underground storage of gases, zones of tectonic disturbances belong to dynamically unstable natural object. Such objects are capable of generating variables gravitational-inertial anomalies, which are the obstacles when carrying out high-precision gravimetric survey. The author proposes methodological ways to reduce their impact. The author proposes a device for the registration of such variations, which can be used for detection, localization and study dynamically active geological objects.
Key words: endogenous microseismic waves, monitoring of the development of gas condensates fields, graviinertial anomalies.
