The purpose of the work is the obtaining of magnesium silicate ceramic proppants, based on ultrabasic overburden rocks of Kempirsai deposits of chromite ores (Kazakhstan). The chemical and mineralogical composition of ultrabasic overburden rock was studied by chemical, microscopic and X-ray diffraction analyzes. It is established that the main mineral of ultrabasic overburden rocks is serpentine, present in the form of fibrous chrysotile and lamellar antigorite. In the impurities are iron oxides and hydroxides, chrome spinel, carbonates, quartz. Assessment of the use of overburden rocks as a raw material for the production of ceramic proppants was carried out. The sintering interval of overburden rocks was determined at 1280-1300 °C. The sintering firing optimum temperature of ceramics, based on this type of raw material is 1300 °C. It is established that to harden the structure of magnesium silicate ceramic it is necessary to activate the raw material thermally at a temperature of 1000 °C. The influence of binder type on the properties of magnesium silicate proppants, based on the Kempirsai serpentinites was studied. Magnesium silicate proppants, based on ultrabasic overburden rocks, were obtained with the following properties: apparent density – 1.6 g/cm3, strength resistance (52 MPa) – 14%, sphericity and roundness – 0.8; chemical resistance (hydrochloric acid) – 98%, static strength of the fraction 16/20 - 72–118 N/granule. The field of application is oil and gas production, metallurgy and ceramic industries.

In the Bazhenov Formation, framboidal clusters and nodular pyrite formed in the dysoxic–anoxic interface within organic-rich sediments. Some nodule-like pyritized bituminous layers and pyrite nodules are similar to pyritized microbial mat fragments by the typical fine laminated structure. Framboidal pyrite of the Bazhenov Formation is enriched in redox-sensitive elements such as Mo, V, Au, Cu, Pb, Ag, Ni, Se, and Zn in comparison with the host shales and nodular pyrite. Nodular pyrite has higher concentrations of As and Sb, only. Strong positive correlations that can be interpreted as nano-inclusions of organic matter (Mo, V, Au), sphalerite (Zn, Cd, Hg, Sn, In, Ga, Ge), galena (Pb, Bi, Sb, Te, Ag, Tl), chalcopyrite (Cu, Se) and tennantite (Cu, As, Sb, Bi, Te, Ag, Tl) and/or the substitution of Co, Ni, As and Sb into the pyrite. On the global scale, pyrite of the Bazhenov Formation is very similar to pyrite from highly metalliferous bituminous black shales, associated, as a rule, with gas and oil-and-gas deposits. Enrichment with Mo and lower Co and heavy metals indicate a higher influence of seawater during formation of pyrite from the Bazhenov Formation in comparison to different styles of ore deposits. Transitional elements such as Zn and Cu in pyrite of the Bazhenov Formation has resulted from either a unique combination of the erosion of Cu–Zn massive sulfide deposits of the Ural Mountains from one side and the simultaneous manifestation of organic-rich gas seep activity in the West Siberian Sea from another direction.

Abstract Skywave refers to the electromagnetic wave reflected or refracted from the ionosphere and propagate in the form of a guided wave between the ionosphere and the Earth's surface. Since the skywave can propagate over large distances, it has been widely used in long-distance communication. This paper explores and demonstrates the feasibility of skywave for deep resource and energy exploration at depths up to 10 km. Theoretical and technical advancements were accomplished in furthering the skywave applications. A new solution method based on Green's function has been developed to study skywave propagation in a fully coupled lithosphere-air-ionosphere full space model. The model allows one, for the first time, to study skywave distribution characteristics in the lithosphere containing inhomogeneity such as ore deposits or oil and gas reservoirs. This model also lays a foundation for skywave data processing and interpretation. On a parallel line, we have developed a multi-channel, broadband, low-noise, portable data acquisition system suitable for receiving skywave signals. Using the skywave field excited by a high-power fixed source located in the central China, actual field surveys have been carried out in some areas in China including the Biyang depression of Henan Province. The initial results appear encouraging – The interpreted resistivity models prove to be consistent with those of seismic exploration and known geological information, and the exploration cost is only about 1/4 to 1/10 of seismic surveys. These initial successful applications of the skywave theory lay a solid foundation for further verification of the new method.

Abstract The paper reports the results of a comparative analysis of the chemical and isotope composition (δ180 and δD) of mud volcanic waters and formation waters from oil and gas fields. Studies show that the waters discharged by mud volcanoes in most cases are very similar to formation waters. The most characteristic geochemical traits of both waters are elevated concentrations of hydrocarbonate ions, iodine, boron, bromine, and a low content of sulfate ions.

Break Up

A breccia pipe is a cylindrical- or irregular-shaped mass of brecciated rock. A breccia consists of broken, angular fragments of rock cemented together by a fine-grained matrix. Hydrothermal breccia pipes form when hydrothermal solutions force their way towards the surface through zones of weakness or fracture zones and naturally break up the rocks in the process, i.e., hydrofracturing; breccia pipes can also form by collapse. Hydrothermal breccia pipes can contain ore deposits and, as will be discussed later, are associated with some large oil and gas accumulations in southeastern Utah.

Caucasus Region

Для устойчивого развития нефтегазовой промышленности Кавказского реги- она необходимо использовать все имеющиеся геолого-геофизические данные, в том числе и данные глубинных геодинамических исследований. На основе данных о конвективном выносе тепла из мантийного клина к 2D аномалии теплового потока, наблюдаемой на территории Кавказа, произведена оценка угла наклона мантийного клина и скорости субдукции Черно- морской литосферной микроплиты под литосферу Кавказского региона). Восходящие кон- вективные движения в мантии могут выносить мантийные известково-щелочные магмы (с содержащимися в них углеводородами) в приповерхностные слои осадочного чехла, и, следо- вательно, месторождения нефти и газа, должны быть приурочены к зонам, расположенным над конвективными вихрями. For the sustainable development of the oil and gas industry in the Caucasus region, it is necessary to use all available geological and geophysical data, including data from deep geodynamic studies. On the basis of data of convective carrying out of heat from a mantle wedge to 2D anomaly of a heat fl ux observed in the back of the territory of the Caucasus assessment of the angle of mantle wedge and speed of the subduction of the Black Sea the lithospheric micro plate under the lithosphere of the Caucasian region) is made. The ascending convective movements in the mantle can take out mantle calc-alkali magmas (with the metals which are contained in them) to a day surface, and, therefore, ore deposits probably have to be dated for zones of the raised heat fl ux, located over convective fl ows.

Преобразования спектрозональных космических снимков с использованием технологии дистанционной флюидоиндексации (разработана ранее для прогнозирования нефти и газа) позволили установить в пределах площадей Восточного Донбасса наличие аномалий, аналогичных наблюдаемым над газовыми и нефтяными залежами. Результаты проведенных исследований, включающих детализацию аномалий флюидонасыщения, а также анализ геологоразведочной информации различных периодов, свидетельствуют о связи выявленных аномалий с повышенным углеводородонасыщением золоторудных объектов. Так как факт высокого содержания метана в составе газов рудных месторождений является общепризнанным, то выявленный оптико-геохимический эффект может быть использован для прогнозирования и поиска рудных объектов. Для площади развития рудных месторождений Нагольного кряжа приведено сопоставление результатов расчета индекса флюидонасыщения с пространственным расположением рудных объектов. Аналогичное сопоставление, но с результатами опробования разреза скважин, приведено для двух участков Восточного Донбасса Transformation of spectrum-zonal space images with use of the technology of remote fluid-indexation (developed earlier for oil and gas forecasting) allowed to determine, in the limits of Eastern Donbas areas, existence of anomalies, analogous to that observed above gas deposits. The results of carried out research, including elaboration of fluid-saturation anomalies, and also analysis of geological-prospecting information of different periods, testify about connection of revealed anomalies with increased hydrocarbon-saturation of golden ore objects. So far as the fact of raised content of methane in the gases of ore deposits is generally accepted, the revealed optical-geochemical effect can be used for forecasting and search of ore objects. For the area of extension of ore deposits of the Nagolny Ridge, the comparison of results of the fluid-saturation index calculation with spatial distribution of the ore objects is adduced. An analogous comparison, but with use of sampling results of the boreholes cross-section, is adduced for the two plots of Eastern Donbas
