The data on geological settings, ages, special features of mineralogy and composition of Sinyushensky Massif granitoids the in north-west part of the Gorny Altay region. The age of the Sinyushensky Massif rocks is 248 ± 0.7 Ma (Ar-Ar dating by biotite). This massif belongs to Permo-Triassic Siberian large igneous province. Sinyushensky Massif granit-leucogranites are drastically different from typical intra-plate A-type granitoids. They correspond to S-type granitoids by mineralogy and petrochemical characteristics, and are characterised by the increased fluorine and LILE concentrations. Nd isotopic composition corresponds to that of the metasedimentary rocks of the north-west Altay’s upper crust. The formation of Sinyushensky Massif granitoids melts was the consequence of continental crust rocks melting. The enrichment by LILE and Ce-group REE associates with the influence of deep fluids caused selective melting of mica and accessory minerals.

In the southern of Far East Russia region, the principles of the constant ratio of natural radioactive elements (NRE) has been formulated by the author using a large volume of statistical data, supported by mathematical computations and affirmed by a long-term field experience. It was developed the basis for determination of geodynamic types of the magmatic (MC) and structural-substantial (SSC) complexes using trends of NRE ratios (trends of the ore type and magmatism). A field experience affirms a lot of anomalous cases that do not adhere to the stated principles; it is necessary to clarify the causes for their occurrence. The characteristics of Archean complexes of the region have almost not been taken into consideration in development of above mentioned principles; therefore, these principles are still not universal and need further improvement. For this purpose, the average values of NRE ratio in MC and SSC obtained along the reference profile Dzhalinda-Tommot are analyzed jointly with the deep modeling data (based on seismogravitational, MTS and geothermal profile data). Particular attention is paid to distinguishing the areas where MC and SSC with anomalous NRE ratio are concentrated; their relationship with the features of the deep structure of the region has been proven. The lowered requirements for the accuracy of the method and relative simplicity of processing allow using the fund materials of the past years airborne geophysical surveying scale of 1 : 200 000-1 : 5 000 000 and simplified methods for estimation of average NRE ratio characteristics.

On the base of new petrochemical and geochemical data with specificity in the compositions of rock-forming and ore minerals was determined the conditions of formation of Ti-Fe-V mineralization in the two-pyroxene gabbro of Medvedevskoe deposit. Two stages of formation of abundant mineralization were distinguished. They occur in the rhythmically stratified amphibole-saussuritizated gabbro of early cumulatively-magmatic stage and in the late-magmatic (subsolidus) stage. Staging of ore-genesis during the late-magmatic phase is related to the non-equilibrium of residual fluidized melt enriched with water and chlorine to the previously extracted rock-forming and ore minerals (pyroxene, plagioclase, titanomagnetite and ilmenite) which formed a primary magmatic frame and layering of ore-bearing rocks.

The original cause of the Late Mesozoic tectonic-magmatic and mineragenic activation at the Pre-Cambrian Aldan Shield was the existence of the stagnated oceanic slab in the mantle transitional zone. Dehydration of the slab rocks (especially those on its boundaries) and accompanying events promoted the lower mantle derivatives to be involved into the ascending upper mantle flows (plumes) and favored the formation of the productive ore-magmatic systems.

New data on the mineral and chemical composition of the ore, host rocks and technosoils of tailings gold-molybdenum deposit Davenda are outlined. The mineral composition of the ore (%): quartz (96), molybdenite (1, but on average 0.26), pyrite (7), chalcopyrite (2), sphalerite (0.07), galena (to.1), sulphosalts (0.02), bismuthinite (0.2), scheelite (up to 0.02), tungsten (up to 0.01), bornite (0.03), tetradymite (to 0.001) emplektite (rare occurrences) and gold (up to1817g/t). In the oxidation zone developed various sulfates, including large (up to10 cm) gypsum crystals, chalkanthite, malachite, azurite, brochantite, molybdenite, ferrimolybdite. The contents of the main chemical elements, which compose technosoils of tailing, exeed their clarks. Exceptions are zinc, tin, and yttrium. Especially high concentration factors for arsenic, bismuth and molybdenum, which indicates the imperfection of applied technologies of the ores enrichment. The distribution of chemical elements in the geotechnogenic system: productive mineral complex (ore + host rock)→soil→technosoils →plants. Revealed the share of Mo, Zn, Cu, Pb mobile form, in technosoils. Identified acid-base characteristics of technosoils. It was found that the most important of the mobile forms is a water-acid-ion exchange, to a much lesser extent - organic elements.

Olivine and chrome-spinel compositions from chromitites and ore-bearing metamorphosed ultramafic rocks of Rai-Iz massif were compared. It was established that olivine and spinel ferruginosity are directly proportional and increase monotonically from chromitites to ultramafic rocks that indicates the existence of equilibrium in the ore-rock system. The compositions of accessory spinel are in agreement with compositions of ferrichromite and chromemagnetite, which are highly oxidized spinel group minerals, typical for metamorphic ultramafic rocks. The obtained results suggests that chromitites and metamorphosed ultramafic rocks are products of a single process which is metamorphic differentiation of ultramafic rocks.
