-
(2001)Humic acids from highly decomposed peat were subjected to oxidation with alkaline cupric oxide (CuO) at 170°C (single oxidation). Oxidation products were isolated as three fractions, oxidized humic acids, fulvic acids and ...
-
(2003)It is difficult to reconstruct the pre-Cenozoic history of western Kamchatka, because Mesozoic deposits are fragmentarily exposed here. The Palana section, the most complete one among Mesozoic sections of the region, is ...
-
(2002)Olivine grain boundaries in deformed aggregates of olivine + basalt and partially molten lherzolite were analyzed with various electron microscopy techniques to test for the presence of thin (0.5-10 nm) intergranular melt ...
-
(2004)This paper presents geological, isotopic-geochemical, and geochronologic data on bimodal trachybasalt-trachyte and trachybasalt-trachyrhyolite-comendite associations of the Tsagan-Khurtei graben of Western Transbaikalia. ...
-
(2001)The structural behavior of synthetic gahnite (ZnAl2O4) has been investigated by X-ray powder diffraction at high pressure (0–43 GPa) and room temperature, on the ID9 beamline at ESRF. The equation of state of gahnite has ...
-
(2003)The subdivision and correlation scheme of the Vendian Complex is revised based on new data from outcrops along the eastern margin of the Baltic Shield (the southeastern White Sea area) and recently drilled boreholes. ...
-
(1997)The paper describes the results of the crustal and upper mantle studies in the region using the areal DSS technique. The territory covered is about 400 thousand sq. km. A number of contrasting anomalies have been discovered ...
-
(2005)The salt tectonics of the Glueckstadt Graben has been investigated in relation to major tectonic events within the basin. The lithologic features of salt sections from Rotliegend, Zechstein and Keuper show that almost pure ...
-
(2001)The Lesnaya thrust on the Kamchatka isthmus is part of the collisional suture separating the Upper Cretaceous complexes of the Achaivayam-Valaginskiy paleoarc from coeval terrigenous complexes of NE Asia continental slope. ...
-
(2001)The southern Urals of Russia contain a well-preserved example of a Paleozoic arc-continent collision in which the intraoceanic Magnitogorsk volcanic arc and its forearc basin sediments accreted to the East European Craton ...
-
(2001)The structure of active continental margins is characterized by development of volcanic and terrane fold-and-nappe orogenic belts, which collectively ensure the growth of continental margins both in area and crustal ...
-
(1999)The adsorption of organic molecules at mineral-fluid interfaces has a profound influence upon geochemical reaction and transport processes, yet little is known about the in situ structures or properties of organic layers ...
-
(2003)The Uralian Foldbelt is a natural western boundary of the West Siberian Petroliferous Megabasin. Lithotectonic zones making up the eastern sector of the Urals have a general NNE trend. They successively plunge beneath ...
-
(1990)The hydrothermaily worked reservoir rocks have predominantly vertical zoning. Up section through each of the highly permeable members, one observes a complication of the clastic component of the rock. Highly variable ...
-
(2004)The structure of CaGe2O5 between room temperature and 923 K has been determined by X-ray powder diffraction. A continuous phase transition from triclinic C1¯ to monoclinic C2/c symmetry at Tc*=714±3 K is observed. The ...
-
(1999)As a step toward structural characterization of magmatic liquids and to correlate their structure with melt properties, in-situ, high-temperature structural data have been obtained along the joins Na2Si3O7- Na2(NaAl)3O7,and ...
-
(1999)The Miocene andesite formation of southern Kamchatka consists of the Stenovaya, Yuzhno-Bystraya, Akhomteni, Zavoikovo, and Yushino volcano-plutonic rock associations. Each of these associations consists of a volcanic and ...
-
(2001)Semiconducting minerals are a unique class of materials that have a broad range of influence in near-surface geochemical environments. Many are electroactive and play an important role as natural solid phase electron sources ...
-
(2002)Multichannel seismic reflection data acquired by Marine Arctic Geological Expedition (MAGE) of Murmansk, Russia in 1990 provide the first view of the geological structure of the Arctic region between 77–80°N and 115–133°E, ...
