(VIMS) // vvk46@list.ru SOME METHODOLOGICAL APPROACHES OF THE IDENTIFYING OF HIDDEN URANIUM DEPOSITS The identifying and evaluating of hidden ore objects, including uranium deposits, is the most urgent in the world geological community due to the significant depletion of the easily discovered near-surface objects fund over the previous century. It is most effectively solved by Canadian geologists who successfully identify deep-lying uranium deposits of the «unconformyty» type using new exploration technologies. Russian uranium geology is taking its first steps in this direction; in this regard, the article considers the methodological approaches to prediction and searching for hidden uranium deposits of the vein-stockwork and paleochannel types. Keywords: hidden uranium deposits, rift structures, deep geological and structural models of ore objects, geophysical and geochemical methods, tectonic-magmatic activation. P. 3-14 |

The five geochemical methods were used which are MMI (Mobile Metal Ion geochemistry), ISM (Ionic Sorption Method), MDE (Method of Diffusive Extraction), MEFFA (Multi-Element Fine Fraction Analysis), and conventional soil geochemical survey. A comparative evaluation of the efficiency of those geochemical methods is given. Keywords: soil lithogeochemical prospecting, Au-Mo-Cu porphyry ore, Eastern Trans-Baikal, residual dispersion patterns, superimposed dispersion patterns, occurrence modes of chemical elements, selective analysis, efficiency evaluation.

(Rosnedra) // lyashenko.52@bk.ru REGULARITIES OF DISTRIBUTION OF JASPER BODIES IN SPACE AND ANALYSIS OF CHEMICAL FEATURES OF TEXTURE TYPES OF JASPER SOUTH URALS The problem of distribution of Jasper bodies in space is considered, and the main regularities are shown. The author’s systematics of units of a hierarchical series of zoning of Jasper objects is presented. Grouping of Jasper bodies at the level of their texture component is performed. The relationship of Jasper with related, genetically related minerals is shown. The material on the chemical composition of Jasper and Jasper-like rocks is analyzed. The average chemical composition of classic Ural Jaspers was determined. Keywords: jasper, belt, field, Deposit, texture, chemical composition, silica, fault, tuffites. Р. 25-35 |

In recent years, worldwide interest in titanomagnetite ore deposits, which are strategic mineral raw materials of any country, has sharply increased. There are practically deposits on every continent (European states, Asian countries, Russia, Africa, South and North America, New Zealand, etc.). The world forecasted resources of iron ore reach about 600 billion tons, and the explored reserves are 260 billion tons, the world proven reserves of iron ore are 212.7 billion tons.
