-
(2001)A new gold deposit in Eastern Sayan located in a granitoid stock cutting hyperbasites of the Il'chir ophiolitic cover is described. Three types of ore bodies are distinguished: quartz-vein, quartz-muscovite-pyrrhotite, and ...
-
(2001)Evolution of the Euxinian-Caspian basin (Eastern Paratethys since the Oligocene) during the Tarkhanian (terminal early-initial middle Miocene) is considered, and its interrelations with the Alpine-Carpathian (Western ...
-
(2002)Evolution and confinement of biota to concrete sea zones, and paleogeography of the Euxinian-Caspian basin (the Eastern Paratethys since the initial Oligocene) at the beginning of the middle Miocene (Chokrakian) are ...
-
(2004)The Verkhnyaya Indigirka region of Yakutia includes central part of the Glavnyi gold-bearing belt of the Russian Northeast. Besides large placer gold deposits, many of which have been already mined out, this region contains ...
-
(2002)In addition to the genus Anderssonites Syomina, Solovieva, et Bensh, 1987, the direct descendants of the genus Jigulites Rosovskaya, 1948, include the groups "Pseudofusulina" kossovoii Alexeeva et Polozova and "Pseudofusulina" ...
-
(2000)The Pylga Suture Zone is a kind of a suture zone between the Paleozoic-Mesozoic island-arc rocks of the Taigonos Peninsula and the Precambrian rock complexes of the Avekovo Block. This zone is distinguished by its intensive ...
-
(2000)Described in this paper are the tectonic positions, as well as the geologic and seismologic manifestations, of some largest earthquakes which took place in north Eurasia during the last 15 years. Some information is also ...
-
(PANGAEA, 2000-04-17)We present the initial results of a U-Th-Pb zircon ion-microprobe investigation on samples from the Central Belt of Taimyr, in order to constrain its tectono-magmatic evolution. The zircon samples are from a deformed twomica ...
-
(2000)The temperature dependence of silica release from bytownite, a Ca-Al-rich feldspar, was determined in solutions of inorganic and organic ligands at neutral pH from 5°C to 35°C. The apparent activation energy of dissolution ...
-
(1994)The temperature dependence of the formation of polynuclear cationic complexes is analyzed on the basis of a simple electrostatic model of electrolytic dissociation proposed by Ryzhenko and Bryzgalin . It is possible to ...
-
(2001)Examples are presented of three temporal relationships between joints and faults: joints that pre-date faults; joints that are precursors to, or synchronous with, faults; and joints that post-date faults. Emphasis is placed ...
-
(1996)Climatic changes that resulted from the Late Ordovician glaciation coincided with the mass extinction and drastic alterations of the paleozoogeography of marine biota. The extinction of warm-water faunas in epicontinental ...
-
(2001)Conventionally the terrain/topographic reduction is based on the Bouguer Plate, which is flat and extends in the local tangent plane/horizontal plane to infinity. Here we aim at an error estimate of such a "planar ...
-
(2004)The two stable isotopes of Li are significantly fractionated by exchange reactions with clays near the Earth’s surface. The isotopic legacy of this process provides a robust tracer of surface material that is returned ...
-
(PANGAEA, 2003-08-25)
-
(2001)Questions on Tertiary Sanduga suite's toponymy and its section typification are considered. Taking into account the new data on Primorye volcanic plateaus, including the Sanduga suite's stratotype area, the improbability ...
-
(1987)Accepting that the opening or closure of seaways has consequences on the oceanic circulation which in turn influences sedimentation, major changes in Tethyan geometry are checked against major changes in sedimentation. ...
-
(2003)A non-linear theory of transresonant wave phenomena based on consideration of perturbed wave equations is presented. In particular, the waves in a surface layer of a porous compressible viscoelastoplastic material are ...
-
(1995)Involatile hydrocarbons were identified following the heating of 5α(H)-cholestane in water with reaction vessel walls composed of 316 grade stainless steel and borosilicate glass. These analyses were compared with the ...
