(2006)Based on the study of more than 300 isophlebiid specimens from several Late Mesozoic sites in eastern Transbaikalia (Ukurei, Tergen', Glushkovo, and Byankino formations), new genera and species are described: Xeta olovica, ...
-
(2006)The palynological analysis of the Berriasian-Barremian of northern Siberia has once again demonstrated the great stratigraphic value of dinocysts. A succession of ten dinocyst zones has been established. Most of their ...
-
(2006)Six new genera, one new subgenus, and ten new species of trilobites are described from the Upper Cambrian Chopko Formation from a section of the Chopko River, Norilsk District, northwestern part of the Siberian Platform. ...
-
(2006)The period around the Permian-Triassic boundary was marked by one of the most important and interesting events in the evolution of life. The diversity of both marine and continental biotas decreased. The changes were global ...
-
(2006)A new lycopod, Novgorodendron conophorum gen. et sp. nov., is described from the Upper Visean deposits of the Kamenka River, near the town of Borovichi (Novgorod Region). The morphology of the leaf cushions of the new plant ...
-
(2006)A stratigraphic chart is developed of the Upper Cretaceous deposits of northern Siberia based on dinocysts. It covers the period from the Upper Cenomanian to the Maastrichtian, including 15 biostratigraphic units (beds ...
-
(2006)Two species of early lagomorph, Strenulagus solaris sp. nov. (Monogolia, Khaychin-Ula 2 and 3 localities, Middle Eocene) and Gobiolagus hekkeri (Kyrgyzstan, Andarak 2 locality, terminal Lower Eocene), are described. A ...
-
(2006)Body fossils of caddisfly larvae are described for the first time based on material from the Lower Cretaceous of Siberia (Baissa locality, Neocomian). The material includes a fully grown larva of Baissoplectrum separatum ...
-
(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 ...
