(2002)The crystal structure of burnsite, KCdCu7O2(SeO3)(2)Cl-9, a new mineral species from fumaroles of the Tolbachik volcano, Kamchatka, Russia, has been solved by direct methods and refined on the basis of F-2 for all unique ...
-
(1996)The paper present descriptions of the sections of the Saumalkol' Formation situated in the Northern part of the Karasor synclinorium in Central Kazakhstan. Particular attention was devoted to finds of fauna and flora and ...
-
(1990)There is little information about pre-Late Paleozoic volcanism in Siberia because the corresponding volcanic systems were largely eroded during the Mesozoic. However, by studying the few volcanic bodies now known and ...
-
(2001)A thorough revision of the lectostratotype of the Volgian Stage near the Gorodishche Village (Ul'yanovsk region) and neighboring section of the upper Kimmeridgian-lower Volgian (Dubki Village) revealed the radiolarian ...
-
(2003)Three possible scenarios can be proposed for generation of boninite melts in a suprasubduction zone of eastern Kamchatka: (1) plume model [11] that explains specific conditions of boninite petrogenesis under the influence ...
-
(1998)A section of Cenomanian-Santonian deposits in the Transaltai Gobi (southwestern Mongolia) is described and analyzed. In lithological features and composition of ostracode, mollusk, and charophyte assemblages these deposits ...
-
(1998)The described flora is studied near the village of Malomikhailovka, where it is confined to synonymous formation of an intermontane depression at the northern end of the Sikhote Alin volcanic belt. In its dominant taxa and ...

NEW DATA ON CRUSTAL STRUCTURE AT DEPTH UNDER THE CENTRAL PART OF THE KURILE-KAMCHATKA ISLAND SYSTEM (1988)In 1983 and 1984 we ran deep seismic sounding and correlation-refraction shooting surveys in the central part of the Kurile-Kamchatka island system, which allowed us for the first time to directly determine the crustal ...
-
(2001)The effect of trapping a trace element, i.e., increasing element partitioning to the solid phase due to interaction of its atoms with crystal lattice defects, is an important phenomenon in trace-element behavior in geochemical ...
-
(2004)Orthorhombic diarsenides of Fe, Co, and Ni of the löllingite group (löllingite FeAs2, safflorite CoAs2, and rammelsbergite NiAs2) are typical of deposits of the five-element (Co, Ni, Bi, Ag, and U) association and similar ...
-
(1998)Assemblages of spores, pollen, and organic-walled phytoplankton were studied in the Middle Eocene-Oligocene sequence of Severnye Ergeni. The dinocyst zonal assemblages were described, and anomalies in their composition ...
-
(2003)A section of lower and middle Norian deposits in the Tikhaya River lower courses of (the central part of Kotel’nyi Island, New Siberian Islands) is described. After revision, the taxonomic composition of fauna from the ...

NEW DATA ON GEOCHEMISTRY OF THE OLDEST (2.95-3.05 GA) ANDESITE ASSOCIATION IN EASTERN FENNOSCANDIA (2003)The paper presents results of geochemical study of the oldest (2.95–3.05 Ga) andesite association of the Chalka volcanic structure, which is a member of the Archean Vedlozero–Segozero greenstone belt located in the ...
-
(2004)In the Kolyma sector of the perivolcanic zone of the Okhotsk-Chukot Volcanogenic Belt (OCVB), we have discovered manifestations of an unusual complex (gold-silver-sulfide-rare metal) mineralization that can be economically ...
-
(2004)The hydrothermal oil in the Uzon caldera is represented by two fractions (generations) separated in time and, partially, in space. The first generation is observed as green (rapidly turning brown in air) heavy (0.9148-0.9767 ...
-
(2001)Reinvestigation of a fragmentary lindholmemydid turtle from a Mongolian locality Sheergeen Gashoon (late Turonian-Santonian) suggested reassignment to Lindholmemys martinsoni Čkhikvadze, 1975. This restricts the stratigraphic ...
-
NEW DATA ON MALLARDITE (NA2SIF6) DEPOSITED AROUND FUMAROLES OF THE GREAT TOLBACHIK FISSURE ERUPTION (1996)Samples of the material deposited around fumaroles were examined by X-ray diffraction on single crystals and polycrystalline aggregates and microprobe analysis. The material was found to contain a rare sodium silicofluoride, ...
-
(2004)We carried out a new quantitative estimate of the subsurface water (SW) in the major shells of the Earth's crust. The results obtained and calculation parameters are given. According to the updated estimate, the modern ...
-
(1989)Much of the Lok crystalline spur of the Transcaucasus median block consists of Paleozoic granite. These metamorphic rocks constitute mainly the western periphery of the spur, along the right-bank tributaries of the Moshevani ...
