SEQUENCE OF EARTHQUAKE GENERATION IN THE LITHOSPHERE OF THE SOUTHERN HALF OF THE KURILE ISLAND ARC (1989)We investigated the structure and sequence of earthquake generation in a seismic zone in the southern half of the Kurile island arc. The zone is about 150 km wide and about 1000 km long. The investigation was based on an ...
-
(1998)Analysis of local and regional stratigraphic relationships has permitted the assessment of the nature of tectonic structures and their distribution throughout the observed history of Venus, spanning the past several hundreds ...
-
(2001)The latest Mesoproterozoic Burovaya Formation is a 600–1000 m thick stromatolite/mud dominated carbonate unit demarcated by an erosional unconformity into two subformations containing stromatolite reefs of variable size ...
-
(1997)Comparative K-Ca and Rb-Sr data for extremely radiogenic muscovites (#Ca=2300 to 18,700; 87Sr/86Sr=52 to 991) from two unmetamorphosed Archaean pegmatitic rocks from the Jack Hills in the northwestern part of the Yilgarn ...
-
(2001)In order to elucidate high-pressure transformations of high-P clinopyroxene (C2/c) at kinetically low temperature where atoms are not thermally activated, the transformation processes of FeGeO3 clinopyroxene (C2/c) have ...
-
(2004)This study explores a chemo-thermo-dynamic subduction zone model that solves for slab dehydration during subduction. We investigate how changes in the incoming plate's hydration and thermal structure may effect the efficiency ...
-
(2004)High-resolution transmission electron microscopy (HRTEM) affords a close look at the complex structures and intergrowths of the serpentine minerals. All contain alternating sheets of cations in tetrahedral and octahedral ...
-
(2004)Serpentinitic mélanges containing eclogites, blueschists, and jadeitic rocks have been studied within the following foldbelts: Borus (West Sayan), Chagan-Uzun (Gorny Altai), Chara (East Kazakhstan), Kokchetav (North ...
-
(2003)The lithofacies characterization of beds in the Serpukhovian Stage stratotype, the Zabor'e Quarry site near Serpukhov, is presented. Ten members, boundaries of which do not coincide with those of local subdivisions formerly ...
-
(2004)Muratovka Paleokarst at the top of Venevian and Dashkovka Paleosol at the top of Steshevian are described in Zaborje Quarry. The Dashkovka profile is classified as a durisol with near-surface calcrete hardpan. The pre-Moscovian ...
-
(1998)In order to evaluate the mechanism of production of unusual high-Mg andesite (HMA) magmas, Pb–Nd–Sr isotopic compositions were determined for HMAs and basalts from the Miocene Setouchi volcanic belt in the SW Japan arc. ...
-
(2002)Settling velocities and entrainment thresholds of biogenic sedimentary particles, under unidirectional flow conditions, are derived on the basis of settling tower and laboratory flume experiments. Material consisting ...
-
(2001)The study of horned dinosaurs housed at the Paleontological Institute of the Russian Academy of Sciences revealed 19 structural parameters of the postcranial skeleton that distinguish males from females. Based on comparisons ...
-
(1998)An updated analysis of the global paleomagnetic database shows that the frequency distributions of paleomagnetic inclinations for the Cenozoic and Mesozoic eras (younger than 250 Ma) are compatible with a random geographical ...
-
(1986)The structure and seismicity of the Moon is very different from that of the Earth. One point of similarity is that statistics of seismic energy release in both bodies are dominated by the largest shallow-focus events. This ...
-
(2001)Slab detachment (or breakoff) has been proposed as a cause of temperature-related processes associated with subduction, such as postcollisional magmatism, mineralization, and metamorphism. In this study, we quantitatively ...

SHALLOW STRATIGRAPHIC DRILLING APPLIED IN HYDROCARBON EXPLORATION OF THE NORDKAPP BASIN, BARENTS SEA (2002)The Nordkapp Basin is a Late Palaeozoic rift basin characterised by numerous salt diapirs. The salt was deposited in the Late Carboniferous-Early Permian and has been remobilised several times. Upper Palaeozoic and Mesozoic ...
-
(2004)Leg 144 (1995) of the Ocean Drilling Program recovered basalts and volcaniclastic material from the volcanic basement of several guyots in the northwest Pacific, including MIT Guyot in site 878. Tectonic reconstruction ...
-
(2004)Quite unusual shapeless dark diamonds, yakutites, which are widespread in placers in the north of the Siberian Platform, were studied by methods of analytical scanning electron microscopy and analytical transmission electron ...
