-
(2006)Interstratification-periodic or nonperiodic stacking of two different silicate layers along a c*-axis-is common in phyllosilicates. Published evidence indicates that some interstratified minerals precipitate directly from ...

-
(1997)Abundances of trace elements (La, Ce, Nd, Sm, Eu, Dy, Er, Yb, Ti, V, Cr, Sr, Y, and Zr) were determined using a Cameca IMS of ion microprobe in clinopyroxenes and garnets in peridotite xenoliths from Udachnaya kimberlite ...
-
(2001)Based on investigation of more than 170 samples taken from natural outcrops of the Maikop Formation (Oligocene–Lower Miocene) in eastern Azerbaijan, the genetic hydrocarbon potential and the organic matter (OM) maturity ...
-
(2001)The geochemical characteristics of peats and regularities in the distribution of mineral components have been studied in peat deposits in the Altai piedmont. These regularities depend on a number of factors including the ...
-
(PANGAEA, 1992-04-07)Data on behavior of iron, manganese, nickel, copper, and zinc in the zone where acidic volcanic waters of the Yur'eva River (Paramushir Island, Kuril Islands) mix with sea water are presented. Distributions of dissolved ...

-
(2011)Kamchatka Peninsula is one of the most active volcanic regions in the world. Many Holocene explosive eruptions have resulted in widespread dispersal of tephra-fall deposits. The largest layers have been mapped and dated ...
-
(1990)Since the time of Vernadskiy and Goldschmidt, chemical elements have been divided into siderophile, chalcophile, lithophile, atmophile, biophile and the like. In the classification proposed by different authors, though, ...
-
(2003)A large body of published geochemical data on the Phanerozoic granitoids of within-plate, collision, and subduction environments was used to revise the universally accepted methods for the determination of the geodynamic ...
-
(2004)Earlier studies of individual fluid inclusions in salt minerals of some Devonian evaporite basins showed that the brines in those basins were of chloride type with a high concentration of Ca2+. The genetic significance of ...
-
(2001)Results of a field experiment demonstrating the response of a reservoir (Ob reservoir) to the inflow of a restricted portion of an acid mine drainage solution (AMD) derived from the Berikul sulfide tailings is presented. ...
-
(1995)Changes in mineral stability and solubility due to temperature or pressure variations along fluid flowlines are potential causes of metasomatism in monolithologic hydrothermal systems. The conditions under which significant ...
-
(1996)Dynamic models are presented to investigate the consequences of melting and melt transport for stable trace element geochemistry in open systems. These models show that including explicit melt transport in 2-D adds non-trivial ...
-
(1997)Mixing of hydrothermal fluids and seawater at the ocean floor, combined with slow reaction kinetics for oxidation/reduction reactions, provides a source of metabolic energy for chemolithotrophic microorganisms which are ...
-
(2003)The Continental Flood Basalts in Franz Joseph Land, Russia, consist of basaltic andesites and tholeiitic basalts with basaltic andesites always underlying the tholeiitic basalts. Both lava types lack negative Nb-Ta anomalies ...
-
(2003)The ore mineralization at the Vernyi gold deposit in the Baikal-Patom area, eastern Siberia, was produced in two stages (metamorphic hydrothermal sulfide and quartz-vein stages). The compositions of the host and metasomatic ...
-
(1988)To obtain more complete petrological information, we thoroughly studied volcanic rocks of the Sovetskaya Gavan complex in the Koppi River basin on the Sovetskaya Gaan' Plateau and along upper reaches of the Samarga River ...
