(2002)In order to clarify Al2O3 content and phase stability of aluminous CaSiO3-perovskite, high-pressure and high-temperature transformations of Ca3Al2Si3O12 garnet (grossular) were studied using a MA8-type high-pressure apparatus ...
-
(2000)The behavior of monazite concentrate reduced by carbon, especially the decomposed procedure of rare earth phosphates, was investigated by X-ray diffraction , electron probe, TG method and chemical analysis. The results ...
-
(2001)Stability of two-dimensional stationary continental and marine ice sheets is studied using perturbations of ice sheet surface elevation and the margin position about a steady-state solution. Ice accumulation rate at the ...
-
(2002)The Ukrainian Dniepr-Donets Basin (DDB) is a Late Palaeozoic intracratonic rift basin, with sedimentary thicknesses up to 19 km, displaying the effects of salt tectonics during its entire history of formation, from Late ...
-
(2003)At least four styles of complex behavior are recorded in trace fossils: (1) Intricate, programmed behavior that is recorded in complex trace fossils, such as Spirophyton and Zoophycos. (2) Behavior that is complex in ...

STYLES OF SEDIMENTATION BENEATH SVALBARD VALLEY GLACIERS UNDER CHANGING DYNAMIC AND THERMAL REGIMES (2001)Glacier beds provide crucial information concerning past and present ice dynamics and thermal regime. In this paper we present structural and sedimentological data from four valley glaciers (Austre Lovénbreen, Midtre ...
-
(2001)In many areas of the world, the presence of shallow high velocity, highly heterogeneous layers complicate seismic imaging of deeper reflectors. Of particular economic interest are areas where potentially hydrocarbon-bearing ...
-
(2001)Using the principles of electro-osmosis, a sub-sampling technique for clay-rich sediments is introduced that produces undisturbed thin-sections from sediment cores. The fragile sample remains in the same disposable box ...
-
(2004)This article reports the discovery of numerous subaerial exposure surfaces which occur in the ca. 2200 Ma Kuetsjärvi Sedimentary Formation (KSF) from the Pechenga Greenstone Belt, NE Fennoscandian Shield, Russia. The ...
-
(2001)In this article, we report on the results of the investigation of trace and major element contents and compositions of minerals for the representative collection of subalkaline picritic basalts from the Putorana plateau ...
-
(2001)We report the data for melt and fluid inclusions from phenocrysts of subalkaline picrite basalts and tholeiitic plateau basalts from Putorana plateau, Siberian trap province. The analyses of reheated melt inclusions from ...

-
(2002)We present an analytical solution and numerical tests of the epidemic-type aftershock (ETAS) model for aftershocks, which describes foreshocks, aftershocks, and main shocks on the same footing. In this model, each earthquake ...
-
(2003)Cylindrical samples of water-saturated, initially loose, St. Peter quartz sand were consolidated using triaxial deformation apparatus at room temperature, constant fluid pressure (12.5 MPa), and elevated confining pressures ...
-
(1998)Upper Eocene, Oligocene, and lower Miocene units were distinguished in the Lower Cenozoic Machigar and Tumi formations of the Schmidt Peninsula, northern Sakhalin, using distribution patterns of 77 mollusk species. A ...
-
(2001)The isotope geochemistry of ocean island basalts has been used to infer the presence of ancient recycled oceanic crust in the mantle. The helium isotopic ratios of basalts from HIMU sources, having high U/Pb (μ) and low ...
-
(1996)The mechanism by which high-pressure metamorphosed continental material is emplaced at high structural levels is a major unsolved problem of collisional orogenesis. We suggest that the emplacement results from partial ...
-
(1989)One of the important problems in studying island-arc igneous activity is that of its sources. A key problem is that of demonstrating subduction of an oceanic plate beneath an island arc and the involvement of its component ...
-
(2005)Solar-type helium (He) and neon (Ne) in the Earths mantle were suggested to be the result of solar-wind loaded extraterrestrial dust that accumulated in deep-sea sediments and was subducted into the Earths mantle. To obtain ...
