Chalcopyrite and bornite are the main Au-bearing minerals at Cu porphyry deposits,volcanogenic massive sulfide(VMS)deposits,Cu-Ni deposits of the mafic magmatic complexes,and ores of submarine sulfide edifices.Bornite and intermediate solid solutions with wide compositional variations(bnss and iss–high-temperature chalcopyrite,correspondingly),which can scavenge economic concentrations of Au,appear in the Cu-Fe-S system at ore-forming conditions.However,the state of Au in bnss and iss is yet unknown.To solve this conundrum,we synthesized samples with net chemical composition of bnss and iss,studied them by in situ X–ray absorption spectroscopy(XAS),and used the experimental data to explain the Au distribution among natural ore-forming minerals.The sulfide samples were obtained at 495–700℃ in Au-saturated system by means of salt flux method.The bnss contained1.2–1.6 log units more Au than iss:up to 18 wt.%Au in bnss vs 0.4 wt.%Au in iss at 700C.An increase of temperature resulted in the sharp increase of Au concentration in both phases,1 log unit per 100℃ at f(S2)close to S_((l)) saturation.Analysis of Au L_(3)-edge spectra recorded at 25–675℃ revealed that at 25℃ Au exists mainly in the metallic state.At t>500℃ the spectral features of Audisappear,and “chemically bound”Au predominates.The Au form of occurrence in the iss field is interpreted as Au-bearing clusters with a stromeyerite-like(CuAgS)structure.Digenite Cu_(2–x)S and bnss contain Au in a mixture of stromeyeritelike and petrovskaite-like(Au_(0.8)Ag_(1.2)S)clusters.The chemical composition of both forms is close to CuAuS,where the nearest Au neighbors are two S atoms at R_(Au-S)=2.34–2.36Å.Results of the present study allow to determine the state of Au and its concentration in the main Cu-bearing minerals of sulfide ores as a function of the T-f(S_(2))-compositional parameters.Due to the sharp increase of the CuAuS clusters stability with increasing temperature,in high-temperature ores formed at t>350℃ Au enriches Cubearing minerals in comparison with

A comparative study of Epipactis atrorubens in two different forest communities of the Middle Urals, Russia

引用

Journal of Forestry Research 2020年第6期31卷 2111-2120页

作者： Elena filimonova Natalia Lukina Margarita Glazyrina Galina Borisova Tripti Adarsh Kumar Maria Maleva Laboratory of Anthropogenic Dynamics of Ecosystems Ural Federal UniversityEkaterinburgRussia 620002 Department of Experimental Biology and Biotechnology Ural Federal UniversityEkaterinburgRussia 620002

The objective of this study was to compare ecophysiological and morphological parameters of a regionally endangered orchid species,Epipactis atrorubens(Hoffm.ex Bernh.)Bess.,growing in two forest communities(on serpentine and granite outcrops)of the Middle Urals,Russia.Biodiversity,dominance,and phytocoenosis studies showed the colonization of a wide range of plant species on both sites.The physicochemical properties of the soil,chemical composition and morphological features of E.atrorubens,growing under technogenic conditions(asbestos deposits),on serpentine outcrops and in the natural environment of the granite massif were studied for the first time.The serpentine substrate differed from the granite one by its greater stoniness,circumneutral pH and lower contents of available nitrogen and phosphorus.Extremely high concentrations of magnesium were found in the serpentine soil,some 79 times higher than in the granite substrate.High concentrations of nickel(94 times),chromium(59 times),cobalt(17 times),and iron(4 times)were found in the serpentine substrate,higher than in the granite substrate.The differences between the sites for available metal contents and for root and shoot metal contents were significantly less.Concentrations of most of the metals in the roots were higher than in the shoots.Despite higher metal concentrations and lower nitrogen and phosphorus levels in serpentine soils,E.atrorubens had a larger population and greater viability compared to those growing on granite.Plants on serpentine outcrops were characterized by the formation of a larger number of fruits,greater root lengths and thicker leaf blades,compared to plants on granites.The well-developed orchid mycorrhizae contributed to the survival of this species under unfavorable serpentine conditions.Hence,serpentine outcrops formed due to the mining of asbestos could be a suitable substrate for the light-demanding E.atrorubens due to its capacity to adapt to dry,rocky,nutrient-depleted soils and limited competition from other plants.

The Transformation of Power in a City: Social and Philosophical Aspects

The Transformation of Power in a City: Social and Philosophi...

引用

作者： Olga Lomako Olga filimonova Philosophical Faculty Saratov State University

Some aspects of transformation of power resulting from the intersection of macro-social trends and their specific spatial and social forms are studied. As the organizing principle of the analysis, the genealogy method was chosen. In the context of the overall conceptual field of philosophy of society, diverging and integrating trends of organization of urban communities and social networks based on motivated relations are considered. Interest is understood as a network attribute meaning that networks can effectively demonstrate power operations.

为了建立评价油气资源利用效益的方法,根据近几年的经验和现今评价标准的发展趋势以及对未来油气资源的预测,提出了三项对油气资源进行地质-经济评价的基本原则:第一是对石油天然气普遍需求原则,这一原则本身包含了合理开发油气藏的原则;第二是充分利用油气资源的原则,这一原则已被法律所固定,它决定着长期的经济效益,合理有效地利用油气资源关系到合理使用基本生产基金、劳动力和材料;第三是油气田开发的利润原理,根据复杂的国内外市场条件,确定油气田合理的开发方向,以获取最大的利润。执行上述油气田地质-经济评价的基本原则,可以确保石油工业长期稳定的发展、增加油气田的利润、吸收更多的资金,从而确保了国家在全球范围内的长期地质-经济利益。
