(VIMS) // vims@df.ru INFERRED RESOURCES OF URANIUM OF RUSSIA There is the history of establishment and incremental development dynamics inferred resources base of uranium of Russia for the period 1998-2015. it is shown that the main role in spatial distribution of inferred resources belongs to the Eastern part of the country – Eastern Siberia and the Far East, where about 88 % of the resources of categories P2 and P3 and more than 70 % of P1. The analysis considered the distribution of inferred resources based on the expected geological-industrial types of uranium deposits. The attention was drawn to the insufficient implementation of inferred resources of uranium and the need for significant growth in the next 15 years to ensure the reproduction of redeemable 2030 inventory. Keywords: uranium, uranium inferred resources, categories of resources, types of uranium deposits, the production of uranium reserves. Р. 7-14 |

At depths of 0.1 – 0.4 km from the surface of the body have been identified with abnormal density, which indicates the presence of significant amounts of titanium magnetite ores.

There Characteristics of the geological structure of the objects and the mineralogical and geochemical features of ores, among which are highlighted: low-sulphide vein-disseminated (Escondida), stringer-disseminated from low-sulphide to sulphide (San Alberto) and low-sulphide vein-veinlets (Eastern zone). According to the geochemical characteristics of mineralization is related to the products of copper-porphyry ore-forming system. It has been concluded that the described field – typical sites for artisanal mining, which gives a significant contribution to the country’s annual production. The development of such production in our country is, given the large number of small deposits of gold, it would give an additional 5 to 10 tons of gold per year. Keywords: Chile, granitoids, gold, low-sulphide, REE. Р. 19-24 |

(TSGEMI IFZ RAN) // viktor.belyavsky@list.ru DISTRIBUTION OF FLUID-KORYAK-KAMCHATKA REGION ACCORDING MAGNETOTELLURIC SOUNDING Interpretation of magnetotelluric informatiom in the Koryak-Kamchatka region, was carried out in the mode of selection of 3D models to the invariant characteristics of the impedance matrix and the tipper allowed to build the electrical conductivity distribution scheme of the crust and mantle, select conductive blocks under the most activated in the seismic and volcanic region of the structure. They were confined to sublatitudinal, northwest regional faults, north-eastern structures of the crust and upper mantle. Increased conduction band has correlated with the position of low-speed and low-density blocks, which may be due to their fluid saturation.

The main characteristic of the zone is a non-equilibrium state between uranium and its decay products, which does not effectively apply the classical methods of radiometric and gamma-spectrometry based on the measurement of gamma-radiation. The study of geophysical methods of ozones have based on the mapping of the intensive areal or point contiguous anomalies radioactivity mostly natural uranium, near-surface anomalies correlate with higher conductivity and polarizability values in zones of tectonic disturbances contrasting geochemical anomalies of uranium contents in alluvial deposits and radon anomalies. There is formed a statistical search of physical and geological model to determine the size and location of the transfer elements promising geochemical barriers in the surface layer characteristic of the Trans-Baikal Territory.
