(2006)The magmatic andesitic eruption of Arenal volcano on July 29-31, 1968, after centuries of dormancy, produced three new fissural craters (A, B and C) on its western flank and a multilayered pyroclastic deposit emplaced by ...
-
(2006)Laboratory experiments have demonstrated that supercritical water has extremely low solubility for normal sea salts. This fact opens up the possibility for the precipitation of salt from seawater that circulates in faults ...
-
(2006)The western belt of the southern Albanian ophiolites consists of six major ophiolite massifs (Voskopoja, Rehove, Morava, Devolli, Vallamara, Shpati) and two smaller ones (Luniku and Stravaj). Each massif has a distinct ...
-
(2006)Twenty-two sediment cores raised from the central and eastern parts of the Barents Sea have been studied to reconstruct the evolution of the facies system since the Late Weichselian glaciation. Multiproxy records reveal ...
-
(2006)East Greenland is a classical area for the study of the Permianearliest Triassic H.trivialeTriassic boundary. The new ammonoid data indicate that deposition was continuous across the Permianmudstone contact in basinal areas ...
-
(2006)Carboniferous and Lower Permian Carbonate and terrigenous rocks with the total thickness of >4000 m serve as the productive units in the Paleozoic subsalt complex at the eastern flank of the basin surrounding the northern ...
-
(2006)Conditions and scales of the accumulation of dissolved manganese in waters of marine basins with hydrosulfuric contamination are considered. It is shown that the Kalamit ferromanganese nodule field, most probably, originated ...
-
(2006)This report summarizes data on the Permian deposits of the Verkhoyansk-Okhotsk region (tectonics, paleogeography, fauna, flora and stratigraphy). The Verkhoyansk-Okhotsk region covers the area of the Verkhoyansk fold-and-thrust ...
-
(2006)The composite section of upper Maikop sediments compiled for the central part of the Eastern Paratethys is presented. The section (more than 1000 m) comprises the Karadzhalgan, Sakaraulian, and Kotsakhurian regional stages. ...
-
(2006)On the basis of a study of the majority of Permian ammonoids known in Verkhoyansk Region, and an analysis of their age distribution, seven associations and four subassociations are established. These ammonoid associations ...
-
(2006)The results of study of the Ishkinino Co-Cu massive sulfide deposit hosted in ultramafic rocks of the Main Ural Fault Zone are discussed. The ore field is localized in a fragment of Early Devonian accretionary prism composed ...
-
(2006)We use the S receiver function method to study the lithosphere at the Dead Sea Transform (DST). A temporary network of 22 seismic broad-band stations was operated on both sides of the DST from 2000 to 2001 as part of the ...
-
(2006)Thermochemical equilibria are calculated in the multicomponent gas-solution-rock system in order to evaluate the formation conditions of fayalite, (Fe0.88-1.0Mg0.12-0)2 SiO4, Fa88-100, in unequilibrated chondrites. Effects ...
-
(2006)A preliminary definition of the Polystoechotidae (Insecta, Neuroptera) based on wing characters is provided. Tertiary Polystoechotidae are revised; the genus Palaeopsychops Andersen (10 species) and the new collective genus ...
-
(2006)Six new reconstructions illustrate the evolution of back-arc basins in the Black Sea-Caucasus region from the Mid-Triassic to the end of the Mid-Jurassic. The c. 2000 km long Tauric (Küre) basin opened in the Late Permian-Early ...
-
(2006)This review embraces approximately 100 publications on chlorine (Cl) in coal. Topics reviewed in this paper include: (a) historical introduction; (b) some peculiarities of Cl environmental geochemistry; (c) estimation of ...
-
(2006)The study of the final stage of halogenesis is one of the most topical problems of evaporite sedimentation and formation of fossil salt deposits. The spatiotemporal distribution of various sulfate, sulfate-chloride, and ...
-
(2006)A possible interpretation of the Sikhote'Alin accretion system (Asian margin of the Pacific Ocean) assumes that this region underwent an alternation of subduction and transform tectogenesis (here called the tectogenetic ...
-
(2006)Lithostructural composition of the dust storm material (DMS) sampled in the southern Far East in the spring of 2002-2004 has been analyzed. Samples were taken near Vladivostok, where the eolian dust precipitation varied ...
-
MINERALOGICAL AND GEOCHEMICAL ZONING AND GENESIS OF MASSIVE SULFIDE ORES AT THE OKTYABR'SKY DEPOSIT (2006)Fractional crystallization and emanation differentiation of sulfide magma and related mineralogical and geochemical zoning are exemplified in massive sulfide ores of the Oktyabr'sky deposit, Noril'sk district. The mineralogical ...
