-
(2003)Submarine pyroclastic eruptions at depths greater than a few hundred meters are generally considered to be rare or absent because the pressure of the overlying water column is sufficient to suppress juvenile gas exsolution ...
-
(2002)Upland and shield areas of central and northwestern Europe are characterised by an abundance of relict weathering mantles (saprolites). These saprolites, if accurately dated and interpreted, may serve as an important ...
-
(2001)Modern sand from the vast (2430000 km2), high-latitude Lena River watershed occupies a low-lying, mostly unglaciated craton covered by thick, widespread permafrost— totally different from the watersheds of large temperate ...
-
(1998)Analysis of experimental and natural data suggests that a pressure increase leads to an increase in the distribution coefficient of potassium between immiscible silicate and salt (carbonate or chloride) liquids, since the ...
-
(1986)A review of previous work on modern and ancient deep-water facies, processes and models is presented with a new classification scheme involving 40 distinct facies related to 15 conceptually distinct facies groups. These ...
-
(2001)The paper presents an attempt to describe water exchange in Lake Baikal proceeding from interpretation of tracer (freon-12) contents and temperature of water. Destruction of the metastable equilibrium of the surface water ...
-
(1988)For a comparative evaluation of the defect capacities of minerals of various structural types, we used microindentation with a Mikroharterprufer diamond indenter accessory of the MeF general-purpose microscope. The increase ...
-
(2001)Linear regression procedures can be applied to derive spectral endmembers using satellite images and superimposed abundance estimates of known components. A common problem, however, is represented by the spatial variability ...
-
(2001)We consider deformation due to sill-like magma intrusions using a model of a horizontal circular crack in a semi-infinite elastic solid. We present exact expressions for vertical and horizontal displacements of the free ...
-
(2004)Several ductile shear zones developed at depth of 680 - 1200m of CCSD. The main rock types in the shear zone include gneisses and UHP eclogites. The strain axes of deformed quartz in gneisses and stretch garnets and ...
-
(2001)High density of GPS network in the Tien Shan and long period of observations have allowed us to construct a velocity vector field of movement on the Earth's surface and a strain rate field. A compact uniform area of ...
-
(2003)Room temperature investigations on the shear stress and deformation mechanisms of (Mg0.9Fe0.1)SiO3 perovskite are performed in situ up to 32 GPa using radial X-ray diffraction and the diamond anvil cell as a deformation ...
-
(2002)The calculation of the deformation due to shear and tensile faults in a half-space is a fundamental tool for the investigation of seismic and volcanic sources. The solution of the two-dimensional problem of a long inclined ...
-
(2003)This paper analyzes the deformational behavior of mutually interacting spherical inclusions in a multiple inclusion system, considering two physical factors: viscosity ratio between inclusion and matrix (m) and the ratio ...
-
(2001)Experimental and natural investigations of partially molten granite are compared and reviewed. Experiments suggest that deformation of partially molten granite with low-viscosity melt (104 Pa s) exhibits a rheological ...
-
(Федеральное государственное бюджетное учреждение науки Геофизический центр Российской академии наук, 2016)The results of observation of Global Navigation Satellite Systems (GNSS) in areas of large earthquakes are analyzed in this article. The Earth''s surface deformation characteristics before, during and after the earthquake ...
-
(2019)Lava domes grow by extrusions and intrusions of viscous magma often initiating froma central volcanic vent, and they are frequently defining the source region of hazardous explosiveeruptions and pyroclastic density currents. ...
