(2002)A possible mesosiderite meteorite was found in the area of the Putorana Plateau, Noril'sk district, Siberia, Russia. Although this rock resembles a mesosiderite in its hand-sample aspect and in having Ni-bearing iron metal, ...
-
(1996)Continental records of Plio-Pleistocene climatic fluctuations are often confined to fragmentary, localized basins, and not easily dated. One exception is the Confidence Hills of Southern Death Valley. In this study, we ...
-
(2001)The Kolvitsa Belt in the south-western Kola Peninsula formed coeval with the earliest Palaeoproterozoic rift-belts in the Fennoscandian Shield. The Palaeoproterozoic history of this belt comprises the deposition of the ...
-
(1997)The reconstruction of geomagnetic field intensity variations during the last 200 kyr from paleomagnetic data is at present the subject of numerous studies and major debate. There is currently no generally accepted record. ...
-
(2003)An accurate and efficient 3-D finite-element (FE) forward algorithm for DC resistivity modelling is developed. First, the total potential is decomposed into the primary potential caused by the source current and the secondary ...
-
(1995)Three-dimensional (3-D) numerical modelling in a rectangular box is provided for the evolution of mantle structure induced by two floating continents. As initial state we take quasi-steady state mantle convection with many ...
-
(2000)Acid volatile sulfur extracted from ureilite meteorites carries a small 33S enrichment relative to carbonaceous chondrites, enstatite chondrites, ordinary chondrites, and troilite from iron meteorites: Δ33S (=δ33S - 1,000 ...
-
(2002)A high resolution, cross-borehole, 3D electrical resistivity tomography (ERT) study of solute transport was conducted in a large experimental tank. ERT voxels comprising the time sequence of electrical images were converted ...
-
(1986)New barometer based on the equilibrium: CaFe 2 Al 2 Si 3 O 12+2 \hspace{0.17em} TiO 2=2 \hspace{0.17em} FeTiO 3+ CaAl 2 Si 2 O 8+ SiO 2 garnet ( Gr 1 Alm 2) \hspace{0.17em} rutile \hspace{0.17em} Ilmeoite \hspace{0.17em} ...
-
(2002)We introduce a dynamic linear model in which the observation equations are perturbed by a form that has constant (over time), non-random coefficients and may represent the disturbing gravity field under investigation. ...
-
(2001)A sediment core taken from the Sea of Okhotsk, which is located in the western North Pacific rim with an extensive seasonal sea-ice cover, was investigated for lipid class compounds, total organic carbon, total nitrogen, ...
-
(1996)Measurements of Sr/Ca of benthic foraminifera show a linear decrease with water depth which is superimposed upon significant variability identified by analyses of individual foraminifera. New data for Cd/Ca support previous ...
-
(2001)The objective of this paper is to demonstrate the formulation of a numerical model for mass transport based on the Bhatnagar-Gross-Krook (BGK) Boltzmann equation. To this end, the classical chemical transport equation is ...
-
(2004)The reconstruction of the Late Weichselian glacial limits is based on geomorphological evidence combined with geological data. The maximum extension of the Last Glaciation has been established in Southeastern Lithuania. ...
-
(2001)Recent work with broadband sensors has demonstrated that useful data can be obtained from seismic sensors deployed on the deep seafloor for periods as long as 300 sec, but ocean-bottom seismometer (OBS) systems using ...
-
(1994)Four sections from the mid-Atdabanian to lowest Toyonian (middle Cambrian) along the Lena River of Siberia were sampled for carbon isotope stratigraphy. These show a mainly heavy but highly oscillatory δ13C signature for ...
-
(2001)A new computational method for the calculation of shallow water flows with moving physical boundaries is presented. The procedure can cope with shallow water problems having arbitrarily complex geometries and moving boundary ...
-
(2003)A Cenozoic multi-species record of benthic foraminiferal calcite Sr/Ca has been produced and is corrected for inter-specific offsets (typically less than 0.3 mmol/mol) and for the linear relationship between decreasing ...
