-
(2003)The interrelation between conductive and convective (hydrothermal) components of heat release was not taken into account in the previous interpretations of the thermal anomaly in the Baikal rift zone (BRZ). In this ...
-
(2001)The Sakha Republic (Yakutia) is the northern frontier territory of Russia, located partly above the Arctic Circle. It holds important natural mining resources for the country's current and future economic development. A ...
-
(2001)Mining of kimberlite diamond-containing ores in Yakutia has been considered. Deposits of kimberlite ores are under permafrost overburden which is very thick. Opencast mining of the ores is economically non-advisable. In ...
-
UNDERPLATING AS A CAUSE OF THE VOLCANIC CONTINENTAL MARGIN FORMATION DURING MARGINAL SEA SPREADING (2004)Problems related to the rifting zones and continental margins of the opening sea basins include the necessity of explaining the alternation of active magmatic and a magmatic segments of continental margins recognized as ...
-
(2000)Natural impacts in which the projectile strikes the target vertically are virtually nonexistent. Nevertheless, our inherent drive to simplify nature often causes us to suppose most impacts are nearly vertical. Recent ...
-
(2002)Perturbation is an operation defined on the simplex and can be used for centering compositional data in a ternary diagram, applying objective criteria. Because a straight line in the original diagram is still astraight ...
-
(2004)The electromagnetic (EM) activity observed before earthquakes has received a lot of attention of the scientific community. Various aspects have been proposed in order to interpret these observed EM phenomena, and the most ...
-
(1996)Quadrupole mass spectroscopy was used to analyze fluid inclusion volatiles in different types of nonmarine calcites including travertines, phreatic calcretes, hydrothermal vein calcites, and pedogenic calcites. The objectives ...
-
(2001)This paper presents the results of hydrochemical, hydrological, and hydrobiological studies that were conducted in Lake Karymskii in connection with an underwater eruption that had occurred in January 1996. Also presented ...
-
(1996)Presents the results of the seismic stratigraphic analysis of the data obtained on continuous reflection profiles shot above the subsiding areas of the E Kamchatka shelf, which are made up of sediments that were deposited ...
-
(2002)Deformation of porous crustal rock, through diagenesis, tectonic loading or other processes, can change pore volume and affect fluid pressure. The largest stress-induced pore pressure changes occur when fluid is trapped ...
-
(2001)Fluid inclusions were synthesized in quartz from silver oxalate (Ag2C2O4) and a 6-wt.% NaCl aqueous solution to produce a CO2-H2O-NaCl fluid, following the method of previous workers. Synthesis conditions of 500-650°C and ...
-
(2003)High concentrations of free C32bis-homohopanoic acids (up to 433 μg/g dry wt) occur in microbial mats at methane seeps in anoxic Black Sea waters. These compounds show a strong preference for the ‘geological’ 17α(H),21β(H)- ...
-
(2002)The principles of building an information retrieval system (IRS) for the logging and storage of the primary results of spore-pollen analysis are considered. The structure of the IRS Spore-Pollen Analysis (SPA) is described. ...
-
(2004)Using hierarchic ore-formation analysis methods it is shown that thin sulfidization zones in several regions represent the formations, whose composition most fully reflects mineralogical types of polychronous and monochronous ...
-
(2000)Intense magnetic remanence (100-1000 A/m) associated with MD hematite and/or titanohematite and associated with high Koenigsberger ratios (40-1000) indicate that magnetic remanence may dominate the total magnetization if ...
-
(2001)Structure of rocks influences geomechanical processes in rock mass and determines methodology of geophysical instruments. Complex structure of the rocks leads to necessity to design multi-channel systems for monitoring the ...
-
(2002)We used X-ray absorption spectroscopy at the Al K-edge to investigate the atomic structure of biogenic silica and to assess the effect of Al on its crystal chemistry. Our study provides the first direct evidence for a ...
-
(2003)A quantitative kinetic model for the growth of the different garnet porphyroblast microstructures (type 1 and type 2) of the Western Schneeberg Complex (WSC) is presented. These porphyroblasts formed by a multiple nucleation ...
-
UNROOFING HISTORY OF LATE PALEOZOIC MAGMATIC ARCS WITHIN THE "TURAN PLATE" (TUARKYR, TURKMENISTAN) (2002)Stratigraphic, sedimentologic and petrographic data collected on the Kizilkaya sedimentary succession (Western Turkmenistan) demonstrate that the “Turan Plate” consists in fact of an amalgamation of Late Paleozoic to ...
