(2003)We analyzed normal saturated paraffins (n-paraffins) in 70 surface sediments in the northwest Pacific to examine the spatial distribution of organic materials. All sediments show bimodal n-paraffin abundance patterns against ...
-
(2004)Latitudinal variations in model biogenic apatite δ18O values were calculated using fractionation equations of vertebrates and weighted rainfall δ18O values along with mean annual air temperatures provided by IAEA–WMO ...
-
(2001)Lattice defects in lawsonite have been studied by transmission electron microscopy. It is proposed that twinning and easy glide systems are 1/2[110].{110}; the easy glide planes are coincident with twin planes. This mineral ...
-
(2003)Diffusion and solubility of Ar in optically clear natural and synthetic quartz crystals were examined at ~500 to 1200 °C by treating polished specimens in pressurized Ar (1-185 MPa) and characterizing the resulting ...
-
(2001)In order to investigate the evolution of lattice preferred orientation (LPO) obtained during deformation, we carried out post-deformational annealing experiments for rock analog materials, octachloropropane (C3Cl8) and ...
-
(2002)Quartz inclusions within intertectonic garnet porphyroblasts of metapelites from the southern Imjingang belt have a lattice preferred orientation. c-Axis fabrics of the quartz inclusions tend to show a single girdle pattern ...
-
(1990)The systematic, symmetrical distribution of the abundances of minerals that has been identified in the case of the earth and confirmed by data for the moon and meteorites is a general law of the universe, and as a consequence, ...
-
(2002)Vertically overlapping fault segments are common structures in faulted hydrocarbon reservoirs. Experimental work and field observations show a close relationship between the rotation of layers in the region of overlap, the ...
-
(1989)The idea of a concentrically zoned earth, consisting of a number of concentric shells, has long been established in science. But we are only beginning to realize that each shell constitutes a self-contained dynamic system. ...
-
(2004)In a sedimentary environment, quasi‐layered models often can represent the actual geology more accurately than smooth minimum‐structure models. We present a 2D inversion scheme with lateral constraints and sharp boundaries ...
-
(2001)On the basis of a synergetic approach, the phenomenon of layering in igneous melts is considered as a manifestation of self-organization under specific physicochemical conditions. It is assumed that plastic deformation ...
-
(2003)It is shown, using the example of the Baltic large Early Paleoproterozoic igneous province of the siliceous, high-Mg (boninite-like) series (SHMS), that the layered intrusions had been intermediate-depth magma chambers ...
-
(2004)Information on the structure of the upper mantle comes from two main sources. Regional seismic studies provide indirect information on large portions of the lithosphere, and mantle xenoliths provide direct information about ...
-
(2004)Peridotitic clinopyroxene (cpx) and pyrope garnet xenocrysts from four kimberlite pipes in the Kaavi-Kuopio area of Eastern Finland have been studied using major and trace element geochemistry to obtain information on the ...
-
(1997)The long-wavelength geoid and topography are dynamic effects of a convecting mantle. The long-wavelength geoid of the Earth is controlled by density variations in the mantle and has been explained by circulation models ...
-
(2004)The experimental results obtained indicate that under certain conditions sulfide melt in fluid-bearing silicate-sulfide systems separates into a high-S Mss liquid (enriched in Fe and Ni) and a low-S liquid of Cp or Bn ...
-
LAYERING OF THE EARTH AND MULTICELLULAR CONVECTION AS THE BASIS FOR A TRULY GLOBAL GEODYNAMIC MODEL (1989)The plate tectonics theory has laid the foundation for a realistic model of tectogenesis and of geodynamics in general. But we now know that this model explains more-or-less satisfactorily only the kinematics of that part ...
-
(2003)The study of inactive As-bearing tailings impoundments at the Khovu-Aksy mine-site (Russia) revealed high concentrations of As in the porewater of tailings solids and in their aqueous extracts, as well as in adjacent soils. ...
-
(2001)Sodium hexametaphosphate, Na6(PO3)6, is often used as a dispersant in wet grain size separation procedures to obtain the clay-sized (<0.002 mm) fraction of till and soil samples. However, the complexing properties of this ...
