-
(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, ...
-
(2000)Single crystals of tetragonal Ca3Mn2Ge3O12 garnet (space group symmetry I41/a, a = 12.3098(7) Å, c = 12.3277(9) Å) were characterized by X-ray diffraction and transmission electron microscopy. Their structure is topologically ...
-
(1989)Analysis of seismoacoustic sections shows that the Danube suprafan is composed of deposits of a thick stratified sequence, in which members of relatively homogeneous (acoustically transparent) sediments alternate with ...
-
(2001)Using adsorption, X-ray diffraction (XRD), rheological, electrokinetic, dielectric and calorimetric measurements, the mechanism for the gel formation of the alkylammonium derivatives of the Pyzhevsky montmorillonite (Ukraine) ...
-
(2004)This paper presents evaluation of cation distributions from diffraction data collected at high T, P, and is an extension of the spinel structure modelling procedure by Lavina et al. (2002). Optimised cation-to-oxygen ...
-
(1997)This paper presents the results of a 2.5-D simulation of marine magnetic measurements that were carried out during cruise 7 of the R/V Vulkanolog above an active submarine volcano in the Kermadec island arc.
-
(2004)Chlorine-35 magic angle spinning (MAS) nuclear magnetic resonance (NMR) spectra were collected at 14.1 and 18.8 Tesla fields to determine the atomic scale structural environments of the chloride ions in anhydrous and hydrous ...
-
(2000)The structural transformation of high pH Na-rich buserite (NaBu) to H-exchanged hexagonal birnessite (HBi) at low pH was studied by simulation of experimental X-ray diffraction patterns. Four HBi samples were prepared by ...
-
(2002)The local structures of divalent Zn, Cu, and Pb sorbed on the phyllomanganate birnessite (Bi) have been studied by powder and polarized extended X-ray absorption fine structure (EXAFS) spectroscopy. Metal-sorbed birnessites ...
