(2000)The photogrammetric measurements of the morphological changes in the cone of Klyuchevskoi Volcano and the revision of the other consequences of its 1944-1945, 1984-1985, and 1944 eruptions resulted in the reinterpretation ...
-
(1985)Recent developments in the field of physical aspects of earthquakes, which encompasses in present-day terminology the analysis of focal dynamics and of catastrophic effects of earthquakes, are reviewed. In particular ...
-
(1990)In this paper we present and discuss new data on the petrography and chemistry of the principal ore-forming minerals in the lavas of the Piyp volcano and investigate their geochemistry; the data include the first determinations ...
-
(2003)The paper presents a geodynamic interpretation of the deep structure and active tectonics of the northern Tien Shan, with particular emphasis on strike-slip motions, which produced a pull-apart in the centre of the Issyk-Kul ...
-
(2002)Subsurface bacteria also occur in hydrothermal sediments with large temperature gradients (up to 12 °C/m) and with population numbers similar to non-hydrothermal sites at temperatures from psychrophilic to mesophilic. At ...
-
(1981)The Academies of Science and the Geodetic Offices of the countries in the Carpatho-Balkan region (CBR) have been examining the recent vertical crustal movements, mostly by geodetic methods. The total length of the levelling ...
-
(2003)We use the Sr-isotopic composition of rock and anhydrite, as a monitor of fluid composition, in DSDP/ODP Hole 504B to calculate the recharge flux to the axial high-temperature hydrothermal circulation. The fluid and rock ...

Recognition of Early Eocene global carbon isotope excursions using lipids of marine Thaumarchaeota. (PANGAEA, 2013-10-06)The Paleocene-Eocene Thermal Maximum (PETM; ~56 Ma) and Eocene Thermal Maximum 2 (ETM2; ~53 Ma) are geological short (<200,000 years) episodes of extreme global warming and environmental change. Both the PETM and ETM2 are ...
-
(2001)Classification of remotely sensed images is a rich research field wherein techniques from conventional statistics to recent developments such as Artificial Neural Network, Fuzzy logic etc. has wide applications. Conventionally ...
-
(2003)Mantle plumes are recognized by domal uplift, triple junction rift-ing, and especially the presence of a large igneous province (LIP), dominated in the Phanerozoic by flood basalts, and in the Proterozoic by the exposed ...
-
(1995)Integration of the neutron energy distribution for a water-moderated reactor with the most recent cross-section data yields mean recoil energies of 177 keV for 39K (n, p) 39Ar, 969 keV for 40Ca (n, α) 37Ar, and 140 eV for ...
-
(1999)In order to resolve the controversy over how to interpret experimental H2O speciation results using in-situ and quenching techniques, we have carried out an infrared spectroscopic study to determine whether the molecular ...
-
(2002)Two end-member types of pyroclastic density current are commonly recognized: pyroclastic surges are dilute currents in which particles are carried in turbulent suspension and pyroclastic flows are highly concentrated flows. ...
-
(1998)A model of Earth accretion in which the composition of the accreting material does not change with time (broadly homogeneous accretion), and the core is formed through metal phase segregation in possibly relatively ...
-
(2003)In northeastern Russia, reconnaissance analysis of the Anadyrsky and Khatyrsky sedimentary basins indicates that oil and gas fields were formed where strata of potential reservoir quality are present, and faults or zones ...
-
(2003)The northernmost Kamchatka Peninsula is located along the northwestern margin of the Bering Sea and consists of complexly deformed accreted terranes. Progressing inland from the northwestern Bering Sea, the Olyutorskiy, ...

RECONSTRUCTING AND MODELLING LATE WEICHSELIAN CLIMATES: THE YOUNGER DRYAS IN EUROPE AS A CASE STUDY (1999)The science of climatology has evolved rapidly during the last few decades due to the growing awareness that global climate is likely to change. Research has been focused on understanding climate change and on assessing ...
-
(2003)Deep-sea sediment pore fluids contain a record of past glaciations in their [Cl] and δ18O. The signal of the Last Glacial Maximum (LGM) ice volume increase remains in the pore fluids as a local peak in each of these species. ...
