The results of CMP seismic data acquisition along regional deep profiles that cross large tectonic elements in the east of the East European Platform are considered. It has been established that the Zhiguli-Pugachev Arch and the Stavropol Depression (southern part of the Melekess Basin), as well as the Volga-Kama Anteclise and Pericaspian Syneclise, conjugate along reverse-thrust faults extending to the lower crust and Moho discontinuity. The position of the southeastern reverse-thrust boundary of the South Tatar Arch has been substantially specified in plan view and illustrated by seismic sections. Based on the results obtained, it is suggested that reverse-thrust faults of different orders are widespread in petroleum provinces in the east of the East European Platform, and this suggestion should be used in geological exploration. The CMP seismic data acquisition is efficient in studying the junction zones of large tectonic elements. It also provides insights into the deep structure of the Earth’s crust and its relationship to the structure and petroleum potential of the sedimentary cover and localization of oilfields. It is expedient to reprocess and integrate earlier seismic data in order to compile tectonic (tectonodynamic) regional maps on a new methodical basis. © 2014, Pleiades Publishing, Inc. Source

The manufacture of motor fuels and chemical products remains a problem of considerable current interest both in Russia and abroad. The 2000s are characterized by a new stage in the development of hydrogenation processes for the conversion of coals into motor fuels. The review summarizes the recent results of research and development works performed at the Institute for Fossil Fuels concerning the improvement and intensification of domestic coal hydrogenation technology under a hydrogen pressure of 6-10 MPa. © 2011 Allerton Press, Inc.

The average concentrations of trace elements in coals from the South Fergana, North Sos'va, Kizelovsk, South Yakutian, Transbaikalia, Pechora, and Zyryansk deposits and some deposits of the Kuznetsk and Primor'e Basins are compared. The degrees of trace element concentration were calculated both on a total coal weight basis (Qi ) for individual basins and on a mineral matter basis (Qi A) with reference to Clarke numbers in clay rocks. Ratios between the concentrations of typomorphic trace elements on a coal mineral matter basis were calculated for the deposits of basins with different geologic-geochemical formation conditions (Xi A ); the concentration ratios between the pairs of typomorphic trace elements in the considered coal basins (Zi) were also calculated. Typomorphic elements are the trace elements with Qi > 1.4 or Q i A > 2. Coal basins of different origin have different numbers of typomorphic trace elements calculated in terms of theparameter Q i and, to a lesser degree, the parameter . Coal basins differ considerably from each other in both the ratios between the average concentrations of the same trace element in the mineral matter of coal (parameter ) and the ratios between the concentrations of two different trace elements (parameter Zi). In the basins under discussion, the mineral matter of coals from formations created in areal rift genesis regions, in particular, Triassic-Jurassic coals and, to a lesser degree, Carboniferous coals, are enriched in trace elements to the greatest extent. Coals from subgeosynclinal formations have a maximum number of typomorphic trace elements (in terms of the average concentrations in the mineral matter), practically the majority of the test elements with the exception of Nb, Sn, Ni, and Sc. Coals from young mobile platforms are characterized by a similar number of typomorphic trace elements with the exception of Nb, Zn, Y, and Yb. Coals from geosynclinal formations have a somewhat smaller set of typomorphic trace elements, whereas a minimum number of typomorphic elements is characteristic of coals from platform basins. © Allerton Press, Inc., 2011.

A procedure for the calculation of minimum consumptions of coals of different ranks for the production of liquid motor fuels and methane from them by direct hydrogenation and gasification followed by the Fischer-Tropsch synthesis is proposed. This procedure takes into account the composition of the initial coal, the degree of conversion of its organic matter into a mixture of CO + H2, and the H2/CO ratio in this mixture. As an example of its application, the yields of liquid motor fuel and methane from brown and black coals (D, G, and SS) from a number of deposits, which are of interest for performing these processes, were calculated. © Allerton Press, Inc. 2011.

Anthracites of thermal metamorphism from different basins of Russia and the Ha-Tu coalfield of Vietnam are characterized, and data on their petrographic and chemical compositions, structure, and properties are presented. Alterations in the structure and properties of Ha-Tu anthracite during thermal treatment are described. Data on anthracite reserves are reported, and possible lines in their advanced use are discussed. © 2010 Allerton Press, Inc. Source
