(1999)According to the present day knowledge, the stratigraphic equivalents of the Early Miocene volcanic rocks of Sakhalin in the East Sikhote-Alin must be the rocks of the Dembi Suite, a constituent of the Kizinsky Formation ...
-
(1995)Linear free energy relationships (LFERs) have been used to assess the general character of rare earth element (REE) solution complexation. These analyses demonstrate that the coherence of interelement complexation behavior ...
-
(2004)The high-pressure (HP) behaviour of a natural orthorhombic and tetragonal edingtonite from Ice River, Canada, has been investigated using in situ single-crystal X-ray diffraction. The two isothermal equations of state up ...
-
(1996)The structure of geminite was studied and compared with that of arsenates of Zn, Co, Mn, and Ca which are chemically close to it. The structural investigation was carried out on a single crystal of geminite from Salcine ...
-
(2006)The crystal structures of natural Ag-free lillianite of fumarolic origin from Vulcano, Aeolian Islands, Italy, Pb2.88 Bi2.12 (S5.67Se0.33) ∑6.00, with a 13.567(1), b 20.655(2), c 4.1216(4) Å, V 1155.0(2) Å3, space group ...
-
(2006)In this paper, comparative evaluation of various local and global learning algorithms in neural network modeling was performed for ore grade estimation in three deposits: gold, bauxite, and iron ore. Four local learning ...
-
(2003)Comparative observations of PdII and PtII hydrolysis in chloride solutions indicate that [PdCl3OH2-]/[PdCl42-] and [PtCl3OH2-]/[PtCl42-] concentration ratios in salinity 35 seawater (S = 35) are smaller than one at a typical ...
-
(2004)The concentrations of authigenic phases of Cd, Re, U, and Mo increase with depth in four 45-cm-long sediment box cores collected along the axis of the Laurentian Trough, Gulf of St. Lawrence. Average authigenic accumulation ...
-
(2006)This paper presents materials of granitoids from the western Angara-Vitim batholith and the country gneisses and migmatites of the Talanchan Metamorphic Complex. The granitoids of the older intrusive phases of the Barguzin ...
-
(2006)We report high resolution molecular abundance data for alkenones, dinosterol, long chain diols and n-alkanols from ODP Site 658 (20°45′N, 18°35′W; 2263 m water depth). These data are compared with previously reported data ...
-
(2001)Essential differences between the bryozoans of the order Fenestellida and those of other Paleozoic orders and Mesozoic-Cenozoic stenolaemates are shown based on the comparative analysis of their morphology and functions. ...
-
(2006)Time-invariant, long-range, and short-range forecasting models were fitted to the earthquake catalogue of Greece for magnitudes 4.0 and greater to optimize their ability to forecast events of magnitude 6.0 and greater in ...
-
(2006)New data is presented for five evolved, low-Ti lunar mare basalt meteorites from the LaPaz Icefield, Antarctica, LAP 02205, LAP 02224, LAP 02226, LAP 02436, and LAP 03632. These basalts have nearly identical mineralogies, ...
-
(2006)The importance of the discovery of jarosite at the Meridiani Planum region of Mars is discussed. Terrestrial studies demonstrate that jarosite requires a unique environment for its formation, crystallizing from highly ...
-
(2004)Cambrian events in the history of the different terranes comprising mosaic-block geological structures of the Altai-Sayan Folded Area is discussed. On the basis of the complex analysis of the paleontological, lithological ...
-
(1998)We selectively review noble gas data for the Earth and meteorites (the Q component) and for the sun (solar wind) and seek to understand possible genetic relationships among these components. The widespread distribution of ...
-
(2000)In the last few years, it has been shown that multi-proxy data are recorded in speleothems and that these secondary deposits can be used to retrieve records of environmental evolution in extra-glacial continental conditions. ...
-
(1999)The Early Miocene volcanic rocks of Sakhalin, constituents of the Chekhov Formation, are separated from the older Late Paleogene volcanics (phase I of Cenozoic volcanism) by a thick normal sedimentary sequence and, hence, ...
-
(2002)There are two basic approaches for estimating flood quantiles: a parametric and a nonparametric method. In this study, the comparisons of parametric and nonparametric models for annual maximum flood data of Goan gauging ...
