-
(2003)A new algorithm is applied to assess the maximum reliability of the parameters of oil and gas pools in the truncated Pareto series. The obtained estimates are processed using the Monte-Carlo statistics.
-
(2001)Laboratory simulation of wave shoaling over a medium sand bed (mean size=250μm) for a range of wave conditions (a natural spectrum, symmetrical and asymmetrical wave groups) showed that a distinct horizontal fractionation ...
-
(2001)We examined adsorption equilibrium and kinetics of an aquatic fulvic acid (XAD-8 resin extract) onto goethite (α-FeOOH). Molecular weight distributions were determined using high-pressure size exclusion chromatography ...
-
(2003)Charcoal analysis was conducted on sediment cores from three lakes to assess the relationship between the area and number of charcoal particles. Three charcoal-size parameters (maximum breadth, maximum length and area) ...
-
(2001)A correlation between melt inclusion composition and host crystal size has been discovered in a basaltic ash deposit from a volcanic arc setting. Least-evolved melt inclusions, featuring high H2O-CO2 saturation pressures, ...
-
(2001)The skarns and genesis were studied of the Huanggang Fe-Sn deposit and the nearby Sumugou Zn-Pb deposit in Inner Mongolia, China. In the Huanggang mine, Nos. 1 to 4 Fe ore bodies are arranged along a calcareous horizon ...
-
(2004)The Gumeshevsk copper skarn deposit, which is known from the early 18th century thanks for its high-quality malachite, is located in the eastern, marginal part of the Tagil volcanic zone in the Central Urals. The deposit ...
-
(2002)Skarns with magnetite-pyrite-chalcopyrite mineralization develop in the inner-contact portion of a D 3-C 1 small intrusion of quartz diorite porphyry. The bimetasomatic zoning of the skarn bodies comprises the following ...
-
(2001)When a piece of flint is broken to form an artifact, and then buried in sediment at a site, its outer surface is exposed to a higher beta-particle dose rate than is experienced by the interior of the flint. A layer about ...
-
(1998)Amodel with a new type of delamination of the lower lithospheric mantle is proposed to explain the Pliocene to recent tectonic evolution of the Eastern Carpathians. We suggest that, after the continental collision in middle ...
-
(2004)The problem of short-term earthquake precursors is discussed. In contrast to the increasing number of reports on short-lived precursors of various types, direct strain measurements cannot detect clearly expressed preseismic ...
-
(2001)A theoretical 3D model of a fault region includes a slip-dependent friction, tectonic loading from the sides, and deterministic, continuous time formulation of governing equations. The model reproduces such properties of ...
-
(2001)Hillslope runoff was studied in a subarctic, subalpine environment to improve understanding of runoff generation processes and the mechanisms whereby water moves from hillslopes to the stream. Runoff characteristics of ...
-
(2001)Tracer patterns in soil profiles observed in ten transport experiments using a dye and Bromide are analysed to investigate the spatial distribution of the susceptibility for preferential flow on the slope scale. Flow ...
-
(2004)Determination of long-term slip rate for the Altyn Tagh fault is essential for testing whether Asian tectonics is dominated by lateral extrusion or distributed crustal shortening. Previous slip-history studies focused on ...
-
SLOWNESS-WEIGHTED DIFFRACTION STACK FOR MIGRATING WIDE-ANGLE SEISMIC DATA IN LATERALLY VARYING MEDIA (2004)Wide-angle prestack depth migration is an important tool for studying the nature of reflecting boundaries in the earth's crust. The slowness-weighted diffraction stack (SWDS) method has been used to incorporate both two-way ...
-
(2001)The application of the Sm–Nd isotope system of scheelite to dating of low-sulfide, quartz-vein hosted Au mineralization is still under discussion. In the present work, new Sm–Nd and Rb–Sr data for scheelite from the giant ...
-
(1989)The Dzhugdzhur pluton, the largest in the East Asian anorthosite belt, is situated on the south margin of the Aldan shield. Sm-Nd dating of the Dzhugdzhur independent anorthosites indicates their Proterozoic age and, ...
-
(1988)This paper presents the results of an Sn-Nd isotope investigation of rocks from the anorthosite-granite association of the Ukrainian Shield. Geological data suggest that this association is the latest in the series of ...
