(2006)Results of the study of isotopic compositions of C, O, S, and Sr in late Precambrian sections of the Patom Complex and its analogues are presented. Total scatter in δ13C values is more than 21% (from -13.5 to 8.1). The ...
-
(2006)The Kurile Arc consists of at least 100 submarine volcanoes and 5 submarine caldera located mainly in the rear arc. The arc is seismically very active, particularly in the south, and is characterized by extensive volcanism ...
-
(2006)The minerals of Oldoinyo Lengai natrocarbonatite lavas are unstable under atmospheric conditions. Subsolidus mineral assemblages in natrocarbonatites were studied in 105 samples from contemporary eruptions ranging from ...
-
(2006)Asteroids tens to hundreds of meters in diameter constitute the most immediate impact hazard to human populations, yet the rate at which they arrive at Earth's surface is poorly known. Astronomic observations are still ...
-
(2006)~82 000 P and S arrival times from ~3000 sources recorded by ~250 seismic stations from the revised ISC catalogue are employed to study a circular area of 6. radius centred on the Dead Sea.We use the linearized tomographic ...
-
(2006)We present palaeomagnetic results from Lower Cretaceous rocks in Bikin area of the Alchan basin (46.5°N, 134.7°E), Sikhote Alin orogenic belt, Far Eastern Russia. A high-temperature magnetization component with maximum ...
-
(2006)An internally consistent thermodynamic database has been compiled for the Ag-Se (-II, 0, +IV)-S (-II, +VI)-Cl-O-H system on the basis of published experimental data. This database is fit for predicting the chemical properties ...
-
(2006)A fish otolith assemblage from the Messinian 'Lago-mare' deposits of the Colombacci Formation cropping out in the Montecalvo in Foglia Syncline, Marche, central Italy, is described. The assemblage displays a low diversity ...
-
(2006)The Southern Prince Charles Mountains (SPCM) are mostly occupied by the Archaean Ruker Terrane. The Lambert Terrane crops out in the northeastern part of the SPCM. New geochemical and zircon U-Pb SHRIMP ages for felsic ...
-
(2006)It is shown that globular phyllosilicates subjected to deep categenesis are abundant in Middle Riphean sandstones and siltstones (lower subformation of the Arymas Formation) of the Olenek High. Their detailed structural- ...
-
(2006)The results of tectono-metallogenic, geological-structural, mineralogical, isotopic, and thermobarogeochemical studies at the Alshar deposit and in the adjacent area are discussed. The data obtained show that the gold ...
-
(2006)The current concepts of two competing sources of manganese deposited as oceanic Fe-Mn ore are reviewed and assessed critically. A new solution of this problem proposed in this paper is a further development of fundamental ...
-
(2006)The Sr, Nd and Pb isotopic compositions for the Kovdor phoscorite-carbonatite complex (PCC), Kola Peninsula, NW Russia, have been determined to characterize the mantle sources involved and to evaluate the relative contributions ...
-
(2006)Several gas seeps and near-surface gas hydrate deposits have been identified in 850-900-m water depth on the continental slope offshore Batumi, Georgia (eastern Black Sea) using deep-towed high-resolution sidescan sonar ...
-
(2006)The validity of some data in Karakhanian et al. [Karakhanian, A., Djrbashian, R., Trifonov V., Philip H., Arakelian S., Avagian, A., 2002. Holocene-historical volcanism and active faults as natural risk factor for Armenia ...
-
(2006)The meteorite collection of the Russian Academy of Sciences is the largest and most unique collection of meteorites in Russia, and one of the famous meteorite collections in the world. The collection contains more than ...
-
(2006)Results of the first detailed study of mineral and chemical compositions in the rift zone of Iceland near the town of Hveragerdi are presented. The major clayey components represented by dioctahedral smectites (mainly, ...
-
(2006)We propose a new technique to obtain source spectra and seismic moments of regional earthquakes from envelopes of seismic coda. As compared to existing methods, our approach is based on a physical model of the scattering ...
-
(2006)New isotope data on Lower Cambrian rocks of the Irkutsk amphitheater are reported in three communications. The first communication is devoted to the sulfur isotopic composition, which is most sensitive to ostsedimentary ...
-
(2006)The current concepts concerning the genesis of the unique ore-bearing reefs of the Witwatersrand Basin and its gold resource potential are considered. The results of microscopic examination of ore from the Black, Ventersdorp ...
