Campos C.(., Sinichenko E.K., Gritsuk I.I.
Abstract
In Ecuador, Manabi province is considered to be “specialized” in the field of agriculture. So, in 1990, according to the Integrated Plan for the development of the resource water of the province of Manabí (PHIMA), 7 projects of multiple purpose for irrigation, hydroelectric power generation and supply of drinking water were identified.The estimation of water needs was carried out on the basis of a population growth until 2050. Accordingly, established that the population of Manabí by 2020 will be 2’130, 000, and the total area of the irrigation surface will be in the order of 51900 hectares.Calculations show that the annual total volume of water required to meet the needs of irrigation and water supply will be 1,127.49 million cubic meters.Depending on the needs of water resources for water supply and for irrigation, hydrological, topographic and geological information gathered in 1989 identified certain sites close for the design of dams, as well as their heights and dimensions of the reservoirs.Having elapsed since more than 25 years, with updated meteorological and topographical data, proposes a consistent scheme for the development of water resources in river basin of Manabí, Ecuador.

Abstract
The article reflects an overview of the oil industry of the Republic of Yemen, are summaries in the schedule to change the figures of oil production in the country. Shows the overall political and economic situation affecting the drop in the oil industry of the country. We consider the infrastructure of production facilities, the organization of the development on the type of concessions. The article deals with information about the known geology of the country and the largest oil basin included most of the oilfacilities, shows geological map of the consolidated stratigraphic section and map the location of the country’s sedimentary basins. Presents figures on the country’s resources from different sources as well as data on species composition and physical properties of the oil produced in the region. The tables are consider concession blocks, the boundary between these blocks, the companies operating or involved in their exploration, the area of these blocks, as well as the map of the location of the blocks across the country. We consider the marketing component of the oil industry of the country in terms of exports and domestic consumption. Dislike export trends, leading to the country’s oil import needs of heavy products. The article gives a general understanding of the catastrophic situation of the oil industry in the country in which the major income budget come from the production and sale of oil. The main problem is consider political instability, as well as attacks on oil transportation facilities. Coverage of this issue is overdue because of the lack of such information in Russian and is available in English and Arabic information does not create an overall picture of oil industry complex of the Republic of Yemen.

GRAVITATIONAL TECHNOLOGY FOR THE ASSESSMENTAND COMPLEX DEVELOPMENT OF TECHNOGENIC FORMATIONS OF PRECIOUS METALS
Kurganov K.P.
Abstract
In article gold mining problems at deficiency of stable stocks, exhaustion of a source of raw materials and lack of scientific and technical progress in development of new technologies are stated. Resource potential of technogenic complexes of Russia is estimated at 50-60% of the metal extracted in the country. Over the last 50 years when developing scatterings the content of gold was reduced by 10 times(with 5 to 0,5 g/m3). Thus the high prices of energy carriers and growth of non-productive costs can’t compensate the even constantly growing prices of precious metals.At gold mining from loose fields, enrichment is carried out by easy gravitational ways mainly on lock devices of deep and small filling. Two-stadial enrichment or otsadochny technologies is less often used. Gold of fraction (-0,25 mm) is extracted by lock devices no more than for 5-10%, and production growth thus is provided due to accumulation of volumes and productivity (extensive growth). In this regard it is necessary to provide the theory of economic growth of the American economist of the Nobel Prize laureate of 1987 Robert Solou. In his opinion, investment into cars and the equipment, bigger use of natural, manpower reserves can’t be a source of economic growth on a long-term outlook. Technological changes, professional development of labor and the best organization of work can be the only source of intensive growth.The gravitational technology for an assessment and development of technogenic complexes of precious metals is offered. In JSC SEVER of the Republic of Sakha (Yakutia) it is created and semi- industrial concentrating installation - basic option (the Patent Russian Federation No. 2483807) passed tests. Unlike the existing devices and technological schemes, the declared technology has the distinctive features:allows to extract gold and the accompanying mineral complexes from all products of classification including slurry (a class -0,1 mm);there is no enrichment on lock devices (are established only on control operations);the continuous controlled exit of a concentrate is carried out.The offered technology will find broad application at an assessment and operation of technogenic complexes, off-balance and unpromising objects of precious metals.

UPCLASSING OF EMERALDS
Gorelenkova T.S.
Abstract
Data on the countries producers of emeralds, their contribution to universal production are stated. Huge labor costs on extraction of jeweler emeralds - from the 12th tone of ore are noted, only 10 grams of raw materials are suitable for a facet. Reliable data about world production of emeralds for various reasons don’t exist. Emeralds of different fields differ on mineral inclusions and a chemical composition. About 70% of emeralds are extracted from magmatic breeds and 30% from the metamorphic. It allows to define an origin of emeralds in laboratories. The main diagnostic signs of stones from Kampuchea, Zambia, Brazil, Pakistan are given. A large number (90-95%) of all got stones is exposed to procedures of a laboratory upclassing. The main methods applied to improvement of appearance of stones are stated.Processes of an artificial upclassing conduct to depreciation of jewelry. For establishment of true value of emeralds diagnostics of volume of a laboratory upclassing or its absence is carried out. For this purpose use various methods. Was for detection of filler to consider a mineral under magnifying glass or a microscope until recently enough. But with development of technical means of an upclassing, visual method it is already not enough. Today it is already impossible to estimate extent of artificial impact on a stone without use of the expensive equipment. Besides modern electronic microscopes in gemological laboratories apply the Raman and rentgenoflyuoristsentny spectrometers. On upclassing degree - small, moderate and considerable, emeralds share on three, different on costs, groups. The main objective of such researches is directed on protection of consumers, investors and the extracting enterprises.

NEW TYPE OF LARGE GOLD MINERALIZATION IN YENISEI RIDGE, RUSSIA
Mansurov R.K., Diakonov V.V.
Abstract
The paper deals with principal results of exploration carried out in the Sredne-Ishimbinskaya area. The area studied lies in the central part of the Yenisei gold province. Data are presented on the prospecting methods for lode gold deposits in complicated mountain-taiga landscapes.Еxploration carried out in several consecutive stages. At first prospective area studied by a series of basic geological and geophysical profiles with a complex of geological, geophysical and geochemical research methods, and geochemical prospecting carried out by the leakage flux. As result revealed several potentially ore-controlling plicate-discontinuous dislocations zones, the most perspective localized in the southern part of the area. In the next stage of exploration within the southern part of the area carried out geochemical prospecting on the secondary dispersion halos, schlich and lithogeochemical sampling at the depth of 0.8-1.0 m and geological prospecting routes. As result of second stage of exploration revealed several potentially gold-bearing mineralized zones within the zone of ore-controlling fold-discontinuous dislocation plicate-discontinuous dislocations zone. In the third stage of exploration carried out excavation of pits at intervals of 10-20 m between the pits and bulldozing trench depth of 1 m to localize mineralized zones. The lower productive horizon of deluvial deposits in pits sampled by schlich and lithogeochemical methods. Bedrock in pits sampled by trench sampling. Several sectors were allocated for trenching by bulldozer as result of geological documentation and sampling was the final stage of exploration. The most mineralized areas which are potentially ore zones within the gold-bearing mineralized zones, were trenched to the bedrock and then crossed by a series of boreholes. As result, we have identified ore intersection - the epicenters of the highest gold grades within the mineralized gold zones.For the first time in the region we prognosticate the detection of low grade-high tonnage gold mineralization localized in carbonate-terrigenous sequence of the Aladyinskaya and Kartochki series of the Middle-Upper Riphean.

PALEOVOLCANIC RECONSTRUCTION OF THE MEDNOGORSK ORE DISTRICT
Kotelnikov A.E., Fedosova K.I.
Abstract
The article shows the main results of researches conducted on the territory of the Mednogorsk ore district, located in the Southern Urals. Predecessors applied the existing geological concepts and paradigms to a structure of South Ural. As a result, there is a situation that the objective geologicalpicture still isn’t present. Dependences of minerals of different type on structural elements it isn’t observed though huge actual material is saved up. The view of the territory of the Mednogorsk ore district from the point of view of presence at the historical past of large volcanic structures, which were a source of volcanic sedimentary rocks and industrial concentrations of ore minerals, is given in the article. As a result of the carried-out paleovolcanic reconstruction the Mednogorsk paleovolcanic structure was allocated. Visible diameter of the structure from 30 km in northeast and to 60 km in the northwest direction, other part is overlaid by sedimentary Devonian, Carboniferous and younger deposits. Formation of the structure took place in three stages from the Cambrian to Devon. In the first (basaltic) stage there was an effusive volcanism as a result of which the mafic shield volcano was formed. The shield volcano consists of the volcanic center with a diameter of 11х8 km, the slope (on removal to 20 km from edge of the volcanic center) and the distal area, put by the breeds relating to vent, slope and distal facies respectively. The second (rhyolitic) stage is also effusive volcanism, but it is the stratovolcano, created over the shield volcano, and has mainly felsic, and less intermediate chemical composition. In a structure are allocated it’s own vent, slope and distal facies. In the third stage (a post-effusive era) of structure formation there was an intra facial introduction of intrusive bodies of various forms. The ultramafic bodies are widespread. The era of volcanism was replaced by the era of intensive destruction to what accumulation of terrigenous deposits of Devonian age testifies.

GEOLOGICAL AND GEOCHEMICAL CRITERIA ORE-BEARING GEOLOGICAL FORMATIONS
Filatov E.I., Filatova L.K.
Abstract
Ecological criteria for ore-bearing geological formations are stable association of the same type of geological and ore formations, regardless of their age. Analyzed geochemical and metallogenic specialization and zoning of structural-material complexes.In ontogenesis specific geological formation in its full cycle outlines different levels of geochemical specialization: Syngenetic, premineral originally inherent throughout the volume of the formation; geochemical specialization sinrudnaya arising during rudokontsentrirovaniya, including simultaneously with the formation of the formation; geochemical specialization of secondary, primary nakradyvayuschayasya on geochemical characteristics of the formation due to the influence of her party not paranenetichnyh hydrothermal solutions.The total system chain operations metallogenic prediction and search for information about the geochemical specialization of geological formations and their components enable the following: produce formational interpretation found in the multi-purpose geological and geochemical mapping of anomalous geochemical fields; producing zoning study area on the types of geological formations having varying potentially mineralized with the release of the most productive subformations, phases and facies; to give quantitative estimates of probable resourcesGeochemical criteria of ore-bearing geological formations are primarily in stable correlations petrochemical features ore-bearing rocks and the corresponding fluctuations in the mineral composition of ores (for example, the correlation of potassium content in silicate ore-bearing volcanic rocks ore- bearing volcanic geological formations and ratios of copper and lead ores of pyrite family ore formations).These criteria should be considered in regional and local assessments of the prospects of ore-bearing geologic formations.

Kovjazin V.F., Lepikhina O.Y., Zimin V.P.
Abstract
Results of cadastral assessment of land plots of Gatchina in the Leningrad region are given in the article. According to the Land code of the Russian Federation, results of cadastral assessment of lands are necessary for real estate tax justification. Besides, the cadastral cost of the land plots of settlementshas to be calculated at least once in five years. For these reasons our researches are conducted. Main tasks are the following: to reveal the pricing factors, to estimate the cadastral cost of the land plots intended for placement of residential development and to carry out zoning of an urban area on a specific indicator of cadastral cost of lands. The major pricing factors are considered: the area of the land plot, its proximity to recreation zones, to railway station, distance to healthcare institutions. The importance of factors is determined on the method of the regression and correlation analysis. It is established that the chosen factors for an assessment of the land plots are significant. Also market information on the land plots intended for placement of residential development of Gatchina was collected. Proceeding from the obtained data, the statistical model of the land plot cadastral cost calculation was constructed and the analysis of its quality was made. As a result of research zoning of the territory of Gatchina on value of a specific indicator of cadastral cost of the land plots was carried out, the allocated zones were presented on a thematic map of Gatchina

Leopold D., Houinou G.
Abstract
The reorganization of the sector of the land management in general and the urban land tax in particular, stays nowadays, one of the necessities that must drive to the sustainable development. To reach there, every plot of land has to have Land Title (LT). That’s why, the Government of the Republic of Benin has introduced the massive creation of Land Titles in certain urban areas of the country. During the management of this project, several difficulties have been resolved while others continue. Most of these difficulties find their foundation in the essence and the tenures characterizing the beninese land system. That’s why it will be necessary to regulate them by reforms as legislative as institutional and structural.
