The features of the geological structure of potential deposits are characterized by metasomatic transformations of ore-bearing rocks and the material composition of ore mineralization. The peculiarities of the methodical approach to the study of the Dolgomysovsky gold ore node, which led to the identification of new gold ore objects, are considered. Concluded that the metallogenic potential of known gold ore assemblages in the Urals is high and not fully revealed.

(SGM RAS) // 200962@mail.ru EVOLUTIONAL ASPECTS OF THE LITHIUM METALLOGENY: PRODUCTIVE EPOCHS, MINERAL DEPOSIT TYPES AND THEIR SPECIFIC FEATURES The generation of lithium resources has been taking place since the Mesoarchean and is expressed as a discontinuous series of impulses of variable intensities. Pegmatite type alone represents the lithium metallogeny in three oldest supercontinent cycles – Kenoran, Columbian, and Rodinian. The type is also the main one in the Pangean cycle, but a small part of its resources is concentrated in Li-F granites. Current Amasian cycle is the most various in terms of lithium deposit types: lithium-bearing brines in salars is the main type, while epithermal stratiform lodes, pegmatites, and Li-F granites are less significant. Keywords: metallogeny, lithium deposits, geological history, supercontinent cycle. Р. 10-18 |

The inferred reserves of sepiolite clays are approved on the object. The real composition, technology properties and the possibility of enrichment and modification substantiate the suitability of clays for preparation of salt-resistant drilling mud, cleaning of diesel and vegetable oils and the productions of heat-insulating materials. As a result a new geology-industrial type of sepiolite clays deposit is distinguished. Keywords: Metegerskoe, occurrence, sepiolite, clay, drilling, mud, adsorbent, heat-insulating, deposit, Yakutia.

Malachite and posnjakitewere experimentallyobtained. As a result of the work, it was concluded that the formation of malachite occurs when theacid sulfate waters of the upper part of the oxidized zone of copper-pyrite ores are mixed withhydrocarbonate-sodium groundwater which are intrinsic for the areas of continental salinity. Keywords: malachite, oxidized zone of copper sulphide ores, underground waters of oxidizedzone, geochemical barriers. Р. 40-44 |
