(2006)New bryozoans from the Middle-Upper Devonian (Eifelian-Frasnian) and the Lower Carboniferous (Tournaisian) of the Holy Cross Mountains in central Poland are described: Bigeyella sparsa gen. et sp. nov., B. separata gen. ...
-
(2006)Behavior of gradient and phase velocity vectors of ULF (F < 1 Hz) geomagnetic disturbances was investigated for two earthquake (EQ) events in Japan in 2000 (M > 6) and 2003 (M = 5.8) years. The gradient and phase velocity ...
-
(2006)Geochemical and geochronological studies reveal three distinct groups of Neoproterozoic to Early Paleozoic mafic intrusions in the Biryusa metamorphic massif of southwestern Siberia. Group 1 includes mafic sills that ...
-
(2006)We present the first detailed seismic velocity models of the crust and uppermost mantle around the Mirnyi kimberlite field in Yakutia, Siberia. We have digitized vintage seismograms that were acquired in 1981 and 1983 by ...
-
(2006)We study preseismic behavior of the ULF geomagnetic variations at Karymshino (E158.13, N52.83), Russia, and Matsukawa (E140.94, N39.88), Japan. A depression of ULF power around local midnight is registered several days ...

LONG-PERIOD TRENDS IN GLOBAL SEISMIC AND GEOMAGNETIC ACTIVITY AND THEIR RELATION TO SOLAR ACTIVITY (2006)In the present paper, we are comparing the century-scale trends and decadal variations in seismic activity, and are looking for a relation to century-scale and decadal changes in solar and geomagnetic activity. The possible ...
-
(2006)Rock-Eval pyrolysis and microscopic analyses of Palaeogene terrestrial strata from the western Kamchatka coastal margin, Russia, indicate that good oil-prone source rocks are present in both coals and shales. Hydrogen ...
-
(2006)The Zapolyarnyi volcanic center is confined to the boundary between the oldest volcanic formations (I and II) of the Pechenga complex. Its structure and rock association are significantly different from those of numerous ...
-
(2006)The type species of the genera Echinospirifer Ljaschenko, 1973 Komispirifer Ljaschenko, 1973 and Mennespirifer Ljaschenko, 1973 were revised based on material from the memorial collection of A.I. Ljaschenko. Mennespirifer ...
-
(2006)Fragmentary remains of ornithomimids (Ornithomimidae indet.) from the Lower Santonian (Upper Cretaceous) Kansai locality in northwestern Fergana (Tajikistan) are described, and the composition of its dinosaurian assemblage ...
-
(2006)The solubility of Ni in silicate melts with variable SiO2 content was studied at a total pressure of 1 atm within a wide range of temperature and oxygen fugacity. The maximum solubility of Ni (minimum activity coefficient ...
-
(2006)The partitioning of a number of trace elements (Ba, Nb, Zr, Y, REE, etc.) between orthopyroxene, garnet, and carbonate-silicate melt was experimentally studied using a belt apparatus at pressures of 3.5-4.2 GPa and ...
-
(2006)Nymphs of fossil grylloblattid insects are revised. Newly described taxa are Lemmatonympha gracilissima gen. et sp. nov. and Kaltanympha vorcutensis sp. nov. from the Verkhne-Syr'yaginsk locality (Ufimian, Lek-Vorkuta ...
-
(2006)Members of the genus Glomites played a prominent role as plant mycobionts in the Early Devonian paleoecosystems. Remains of fossil fungi are studied from silicified tissues of the axial organs of several specimens of the ...
-
(2006)A new scheme of successive stages in the formation of radiolarian skeletons is proposed. Successive complication of symmetry patterns is considered. The morphology and evolutionary changes of five types of skeletal shells, ...
-
(2006)The boundaries of the Devonian, Carboniferous, and Permian stages of the Global Stratigraphic Reference Scale (abbreviated to Global Stratigraphic Scale-GSS) are described in relation to the biostratigraphic and/or ...
-
(2006)We have studied the polarized optical absorption and the EPR spectra of Ni-doped beryls grown by hydrothermal, flux and gas-transport methods, and chrysoberyl grown by the Czochralski and flux methods. In beryls, three ...
-
(2006)We have determined trace-element concentrations in fluorite mineral separates, host granites and residual melts trapped in quartz from a well-documented sequence of differentiated Li-F-rich granites in the Khangilay complex, ...
-
(2006)According to known resolution of the IUGS, the International Stratigraphic Commission entrusted its subcommissions with a task to prepare proposals for the official approval of boundaries between Phanerozoic stages. Specially ...
-
(2006)Geochemical data indicate that the protoliths of the overwhelming majority of the metamorphic rocks composing the Fedorov Complex in the Aldan granulite megacomplex were volcanic rocks of three groups, which occur in ...
