(2006)The hyobranchial skeleton of the porolepiform rhipidistian Laccognathus panderi Gross is described. The double composition of the ceratohyal in crossopterygians is proposed. The urohyal of porolepiforms, like that of ...
-
(2006)It is shown that natural chiral catalysts, which could be formed e.g., from optically active amino acids on basic natural minerals, could lead, at early stages of evolution, to the formation of rather complex optically ...
-
(2006)The present-day state as well as the history of isotope organic geochemistry is reviewed. Theoretical aspects of isotope fractionation in a system of complex organic molecules, fractionation of carbon isotopes in the ...
-
(2006)A new unique and diverse biotic assemblage of the terminal Permian has recently been discovered in the town of Vyazniki (Central Russia). The Vyazniki terrestrial community is transitional between Permian and Triassic ones ...
-
(2006)Laboratory experiments showed the effect of the cyanobacterium Microcoleus chthonoplastes on the formation of magnesium calcites, using model solutions (2.14M MgCl2-0.05M CaCl2-0.6M NaCl-0.18M NaHCO3). The conditions of ...
-
A NEW SPECIES OF ADELOPHTHALMUS (EURYPTERIDA) FROM THE LOWER CARBONIFEROUS OF THE KRASNOYARSK REGION (2006)A new species of Adelophthalmus, a genus recorded infrequently in the former Soviet Union, is described from the Tournaisian of the Krasnoyarsk Region. © Pleiades Publishing, Inc. 2006.
-
(2006)Carbonatite dykes are described for the first time from the active natrocarbonatite volcano Oldoinyo Lengai, Tanzania. The dykes are fine grained, with a microporphyritic texture of polycrystalline, granular calcite ...
-
(2006)Thermochemical plumes develop at the core-mantle boundary in the presence of a heat flow from the outer core and at local chemical doping that decreases the melting temperature near the bottom of the lower mantle (this ...
-
(2006)A compilation of data on volumes and masses of evaporite deposits is used as the basis for reconstruction of the salinity of the ocean in the past. Chloride is tracked as the only ion essentially restricted to the ocean, ...
-
(2006)The paragenesis and compositional variation of banalsite-stronalsite solid-solution series, Ba1-xSrx Na2Al4Si4O16, from five new occurrences in nepheline syenite and ultramafic alkaline rocks are characterized; we also ...
-
(2006)The U-Pb geochronological study (by the classic technique and on an ion microprobe) of syenites from central Karelia has established their Archean age. The age values obtained for individual massifs are 2735 ± 15 Ma for ...
-
(2006)The paper examines the effect of air ionization on the thermal balance of the boundary layer of atmosphere. In seismically active areas the increased radon emanation from active faults and cracks before earthquakes is the ...
-
(2006)Eight new species of Ostreioceratidae are described from the Lower and Upper Devonian of Novaya Zemlya, Lower Devonian of the Pechora River basin, North Ural Mountains, and the Zeravshan Range: Ostreioceras admotum, O. ...
-
(2006)Lateral variations in lithospheric strength have been adopted often in flexural modeling (both 2D and 3D) to better fit the observed basement deflections, typically supported by gravity data. This approach provides essentially ...
-
(2006)Evolution of the prokaryotic biosphere is regarded from the system point of view. It starts with the appearance of the first organisms, the ~3.5 Ga date forming the boundary between the observed and imagined biosphere. The ...
-
(2006)A new generic name, Friisicarpus N. Maslova et Herman, is proposed to replace Platanocarpus Friis, Crane, et Pedersen, 1988. Pistillate capitate inflorescences of Friisicarpus nom. nov. are reported from the Cenomanian of ...
-
(2006)DC electric field in the ionosphere above seismically active regions can be formed in a process of external current insertion into the atmosphere–ionosphere electric circuit. This current arises as a result of convective ...
-
(2006)A new genus of organic-walled microfossils of supposed fungal origin, Petsamomyces Belova gen. nov., is described from the black shales of the Pechenga complex of the Early Proterozoic (Kola Peninsula). The find testifies ...
-
(2006)A method for detecting seismomagnetic signals is considered. These signals are generated during the course of the propagation of surface seismic Love wave from far earthquakes. Magnetic field vector of the seismomagnetic ...
-
(2006)The investigation of seismic noise in Kamchatka is carried out for the control of the medium stress condition and search of the strong earthquakes precursors. The main directions of this research are modulation of ...
