-
(2006)This study presents an overview on the geological setting and geochemical characteristics of Pleistocene shallow gas accumulations in eastern Qaidam Basin, NW China. Five largest gas accumulations discovered in this region ...
-
(2002)Experiments have been performed in the multicomponent (natural) bulk system to constrain the conditions of generation and differentiation of a K-rich group II kimberlite (now also referred to as orangeite). The group II ...

GENERATION AND PROPAGATION OF CATASTROPHIC TSUNAMIS IN THE SEA OF OKHOTSK BASIN: POSSIBLE SCENARIOS (2006)Because of the probability of the occurrence of a strong earthquake in the central part of the Kuril–Kamchatka Arc, which corresponds to the seismic gap (SG) region, it is necessary to take into account the possibility of ...
-
(2003)Analysis of infrasonic pressure waves generated by active volcanoes is essential to the understanding of volcanic explosion dynamics. Unlike seismic waves propagating in the earth, infrasonic airwaves offer a relatively ...
-
(1988)According to the meteoritic model of earth differentiation, liquid iron with carbon was generated in the initial period of differentiation. Thus, this event was close in time to the absolute age of the captive minerals of ...
-
(2001)Some anomalous transient electric signals in the ULF band, the so-called SES, are claimed to be earthquake precursors. However, their origin remains widely unknown. Anomalous signals having the same characteristics as the ...
-
(2006)This paper presents the results of a comprehensive experimental study of the formation of granitoid melts at the expense of olivine-normative amphibolites. It was shown that trondhjemite-tonalite and granite-granodiorite ...
-
(2004)To understand the fundamental chemical processes of fluid-rock interaction during the pulverization of quartz grains in fault zones, quartz grains were crushed within pure water. The crushing experiments were performed ...
-
(2003)We show that partial melting of a preexisting mineral deposit during regional anatexis is likely to lead to incorporation of sulfide melt into silicate melt. Simple dissolution of metals in silicate melt during anatexis ...
-
(1989)The Kaidun meteorite is a highly heterogeneous polymict breccia with a unique set of components, namely, various types of carbonaceous and enstatite chondrites. This unusual association strongly implies unusual processes ...
-
(1998)The formation of plate tectonics from mantle convection necessarily requires nonlinear rheological behavior. Recent studies suggest that self-lubricating rheological mechanisms are most capable of generating plate-like ...
-
(1995)Experimental melting studies indicate that secular variations in the geochemistry of many komatiites were determined by secular variations in the depth of melt segregation in plumes. Higher pressures stabilize garnet ...
-
(2006)Mafic to intermediate enclaves are evenly distributed throughout the dacitic 1991-1995 lava sequence of Unzen volcano, Japan, representing hundreds of mafic recharge events over the life of the volcano. This study documents ...
-
(2001)Results of an experimental and theoretical study of the interaction of a first mode internal solitary wave with a localised bottom topography (sill) are presented. Laboratory experiments have been performed in a 10m long ...
-
(1988)The paper presents some results of drillhole logging studies in coal seams that function as seismic waveguides. The use of pulsed elastic-wave generators makes it difficult to identify nonlinear interaction of seismic ...
-
(1989)It is usually assumed that the asthenosphere resulted from partial melting of polycrystalline rocks of the upper mantle. In this connection, it is useful to turn to our earlier formulation of the problem of motion and heat ...
-
(1990)The Dnieper-Donets paleorift (DDR) of Late Devonian age is a typical province of continental, subalkalic and alkalic volcanism that was similar in its principal parameters to the volcanism of classical Cenozoic rift zones. ...
-
(2004)The paper considers the genesis, composition, and mineral assemblages of endogenous borates of the ludwigite-vonsenite series in magnesian skarns after dolomites, rocks simulating their composition, and calcareous skarns ...
-
(1989)The Udokan complex, whose deposits are exposed in the Udokan Range, in the Kalar Range and in the Kodar Massif in the southwestern part of the Aldan shield, traditionally has attracted attention because it is the Proterozoic ...
-
(2006)The genesis and composition of lazurite was considered in the metasomatic rocks and deposits of the Baikal area, Pamirs, Hindu Kush, and other regions. It was shown that formation of lazurite is related to the prograde ...
