(1996)A temperature study (4°C, room temperature, 60°C and 90°C) employing a bacterial in vitro model (Southam and Beveridge, 1994) revealed a role for S and P in octahedral An formation. Ionic Au immobilized by Bacillus subtilis ...
-
(1997)The author's data on the migration and recurrence of great Pacific earthquakes, derived at the global scale of the Pacific belt and at the local scale of the northern Kurils-Kamchatka region, indicate that the southern ...
-
(1998)The OH contents of pyrope garnets synthesised at 1000°C and pressures between 2 and 13 GPa have been measured by infrared spectroscopy. We find that under the same conditions of pressure, temperature, aH2O and aSiO2 the ...
-
(2002)The Okhotsk-Sea plate is interpreted as an old volcanic oceanic plateau bounded by right-lateral strike-slip faults in the east and west, a Middle Cretaceous subduction zone in the north, and by a zone of ongoing subduction ...
-
(2004)Adakites are andesidacite–rhyolite rocks of trondhjemitic affinity characterized by high Na 2 O, Al 2 O 3 , Ba, and Sr contents and high Sr/Y and (La/Yb) n ratios [1, 2]. Adakitic rocks are only formed in a subduction ...
-
(1992)The Bakeyevo biota, the oldest biota discovered in the folded area of the Urals, is described for the first time, and the important stratigraphic consequences of this discovery are examined. The discovery of the Bakeyevo ...
-
(2004)It is established that in Transangara distinctly specified is the most early Neoproterozoic collision event in the range of 865-880 mln years ago. According to the determined geologic position, chemical composition and ...
-
(2001)There is first publication about found the archean ophiolite accotiacion in Irin-Gora, Karelia, Baltic shield, Russia
-
(2001)Ages in the range 3.6-4.0 Ga (billion years) have been reported for the oldest, continental, granitoid orthogneisses, whose magmatic precursors were probably formed by partial melting or differentiation from a mafic, ...
-
(2003)The earliest type of tissue differentiation in carbonaceous thallus has been discovered in the uniquely preserved material from the Vendian of the White Sea area (Russia). A new genus, Archyfasma gen. nov., with its type ...
-
(2003)Since Early Precambrian volcanic rocks are typically strongly altered by superimposed processes, they retain primary composition and texture only in exceptional cases. Such a case is observed in the Early Paleoproterozoic ...
-
(2002)The paper deals with the results of geological-structural, mineralogical-geochemical, thermobaro-geochemical, and isotopic studies of the Oleninskoe gold deposit in the Archean Kolmozero-Voron'ya greenstone belt. According ...
-
(1996)The results of research show that the main geologic events Western Siberia at the end of the Eocene occurred in a succession of negative and positive tectonic movements that brought about regression of the basin. The climate ...
-
(1987)The common upper mantle assemblage olivine-orthopyroxene-spinel may be used to calculate the oxygen fugacity at which mantle-derived peridotites have equilibrated. The equilibrium has been calibrated using the large amount ...
-
(2001)The number of global Carboniferous series and stages should be consistent with those of the neighbouring Devonian and Permian systems. Therefore, two series and seven to nine stages are preferred instead of two subsystems, ...
-
(2004)The fireball accompanying the Park Forest meteorite fall (L5) was recorded by ground‐based videographers, satellite systems, infrasound, seismic, and acoustic instruments. This meteorite shower produced at least 18 kg of ...
-
(2001)A detailed study of the conodont distribution within the condensed carbonate beds around the boundary of Billingen and Volkhov Stages (Lower Ordovician, Arenig) in northwestern Russia confirms the presence of a continuous ...
-
(1997)The results of a comprehensive study of the Ordovician lithology, ostracods, and articulate brachiopods recovered from the Ordovician part of the sections of Gavrilov Yam Wells 1 and 5 are presented. The subdivision of the ...
