(PANGAEA, 2018-08-27)Multibeam echosounder (MBES) data recorded during RV METEOR cruise M84-2 between 26.02.2011 and 02.04.2011 in the Black Sea. The aim of the cruise was to investigate the gas hydrate distribution in sediments of the Black ...
-
(2001)Postcranial axial anatomy of six Jurassic ichthyosaurs is described and used to define a generalized pattern of regional anatomy with four structural units (neck, trunk, tail stock, fluke). Functional interpretation of ...

SYMMETRICAL GRAVITY ANOMALIES AS EVIDENCE OF VARIATION OF THE SPREADING VELOCITY ON MID-OCEAN RIDGES (1989)Visual inspection of records, followed by the mathematical analysis, of the geophysical field of the ocean have long ago revealed a symmetry of several geophysical variables with respect to the axes of the mid-ocean ridges ...

(1997)Primary leonhardite, Ca2.55K1.59Na1.24Fe0.03Al 8.19Si15.87O48 · 13.93H2O, with a primitive Bravais lattice, is a leonhardite that cannot be hydrated and is not formed by the dehydration of laumontite. It crystallizes in ...
-
(2000)Symplectite growth is analysed in terms of non-equilibrium thermodynamics and maximum rate of energy dissipation. For a given reaction, the spacing λ of lamellae or rods is predicted to be proportional to the cube root of ...
-
(2003)We carry out high-frequency analyses of Claerbout's double-square-root equation and its (numerical) solution procedures in heterogeneous media. We show that the double-square-root equation generates the adjoint of the ...
-
(2003)Available geological, geophysical, and seismological data for 39 cases were compared and analyzed to understand the cause of intraplate earthquakes. The results revealed common features which can be used to test models for ...
-
(2002)Syn-tectonic sediments (growth strata) in compressional structures are three-dimensional (3D) features whose geometry reflects both the style of deformation and the distribution of accommodation space in the system. ...
-
(Pleiades Publishing, Ltd. (Плеадес Паблишинг, Лтд) (Род-Таун), 2013)We consider the results of the statistical analysis using the methods of the principal components and canonical coherences applied to the processing of long (1986–2005) time series of hydrogeochemical observations at the ...
-
(2002)In conjunction with the profound ecologic crisis at the end of the Permian, the most conspicuous geochemical event is the worldwide negative shift in the carbon isotopic composition (δ13C) of both carbonates and sedimentary ...
-
(2003)Real-time, temperature-resolved synchrotron powder X-ray diffraction data and Rietveld refinements were used to investigate the behavior of the todorokite structure from 100 to 820 K. At 298 K, the lower valence cations, ...
-
(2000)Material properties are dependent upon atomic arrangement. The structure provides a basis for calculation and for the interpretation of experiment. In the Earth context, mineral structure is composition, pressure and ...
-
(2004)The structure of shafranovskite, ideally K2Na3(Mn,Fe,Na)4[Si9(O,OH) 27](OH)2·nH2O (n ∼ 2.33), a K-Na-manganese hydrous silicate from Kola peninsula, Russia, was studied using synchrotron X-ray radiation and a MAR345 ...

SYNCHROTRON X-RAY POWDER DIFFRACTION STUDY OF NATURAL P2 /N-OMPHACITES AT HIGH-PRESSURE CONDITIONS (2001)Synchrotron X-ray powder diffraction experiments at high pressure conditions (0.0001-13 GPa) were performed at ESRF (Grenoble-F), on the beamline ID9, to investigate the bulk elastic properties of natural P2/n-omphacites, ...
-
(2000)The synchrotron-XRF microprobe set-up at HASYLAB, DESY (Deutsches Elektronen-Synchrotron, Hamburg, Germany) has been evaluated in terms of accuracy and precision of trace-element analysis using a standard-free fundamenta ...
-
(1990)The synergetic principle of the generation of prognostic solutions that are unaffected by stimuli was the basis for the Objective Forecast man-machine system that we developed. This system converts digital matrices of video ...
-
(2004)The study of synmetamorphic granites of the Ol'khon collisional system revealed the abundance of injection veins, dikes, and intrusions. Their emplacement was controlled by ductile strikeslips that postdate and occasionally ...
-
(2001)The stratigraphic record, distribution and composition of the selachian genus Lissodus is briefly reviewed. 38 species are currently recognised, with 26 further records not designated to species level. Teeth of the genus ...
-
(1989)Carbonization, a recently established new type of hydrothermal metasomatic alteration, leads to enrichment of elastic rocks in carbonaceous matter on the flanks of mineralized (primarily gold) zones, as well as in the ...
