Добрый день, Коллеги. Важное сообщение, просьба принять участие. Музей Ферсмана ищет помощь для реставрационных работ в помещении. Подробности по ссылке
Basin analysis is a comprehensive approach to decipher the geological evolution of a basin by constructing the stratigraphic framework and facies relationships, by mapping and understanding the geological structures in light of their historical development, and by examining the physical and chemical properties of rocks and their sedimentological and petroleum attributes. The purpose of the analysis is to identify potential source rocks and reservoir rocks, and to evaluate the maturation, generation, migration, and entrapment of hydrocarbons in a sedimentary basin. <...>

The carstic bauxite deposits of the western flange of the Turgai trough are investigated in geological, petrological, mineralogical, and morphological aspects, as well as to the chemical composition. Special attention was paid to the so-called »beans«, inclusions in the cement of the stony bauxites of that region. These beans have an average diameter from 2 to 20 mm, greater ones are rare, and so are varieties smaller than 1 mm. Structurally, they consist of a gray ferrum-alumi-nium core around which a black coating of alumina-ferruginous matter is wrapped. The inner composition of the beans was examined very carefully in every respect, and on that base some new suggestions about their genesis was put forward.
Energy costs represent a significant component of the total costs of operations for Canada’s mining sector. Directly and indirectly, the energy use in the mining sector is also a significant contributor to Canada’s greenhouse gas emissions. Improving energy efficiency reduces greenhouse gas emissions that contribute to climate changes.
Water supply is critical for ensuring optimal operation of any beneficiation plant. As ore quality continues to decline, the demand on water for mineral processing will only increase. Traditionally, ground and surface water sources have been extensively utilized for mining and beneficiation. In some regions, these sources are proving to be insufficient to meet the increasing demands of this industry, as well as the local municipal requirements. As a result, alternate water supplies must be considered. The purpose of this investigation was to develop a collector that allows for the flotation of phosphate in sea water, while still meeting the grade (>27.5% P2O5) and recovery (>80%) criteria. <...>
Have you tried to walk across a farmer’s field in Montmorillon in France on a rainy October day? Marcel and Bertrand, his father, tried to do so in the fall of 1881 with fatal consequences. We will return to this terrible true story in the first chapter of this book for explaining how the soil at this place made it happen, continuing throughout the rest of the book by explaining how the dreadful soil, in fact, also has extremely beneficial properties in other contexts, like isolation of very hazardous waste.
The name bentonite was suggested in 1898 by Knight for a peculiar claylike material with soapy properties from its occurrence in the Fort Benton unit of Cretaceous age formations in Wyoming (U.S.A.). Hewitt (1917) and Wherry (1917) first established that this particular clay is an alteration product of volcanic ash, although an earlier observation by Condra (1908) suggested this origin for a similar clay from northern Nebraska. Ross and Shannon (1926) presented the following definition which has been widely quoted:

The Be mineral beryl and its colored variants emerald, aquamarine, and “chrysoberyl” (= golden beryl, not the present chrysoberyl) were known to the ancients, and Pliny the Elder had noted that many persons considered emerald and beryl “to be of the same nature” (Sinkankas 1981, p. 20; also Dana 1892; Weeks and Leicester 1968). However, not until 1798 was it realized that beryl contained a previously unknown constituent; analyses before then yielded only silica, alumina, lime and minor iron oxide (Vauquelin 1798; Anonymous 1930; Weeks and Leicester 1968; Greenwood and Earnshaw 1997).
