-
(2006)Tree-ring based mass balance reconstructions developed for Peyto Glacier, Alberta, Canada are compared with measured conditions in the Pacific Ocean over the last century and, using reconstructions of Pacific climate ...
-
(2006)The analysis of earthquake-related signals in hydrochemical time series is still a challenging task. Mostly it is unclear how the geometrical and energetic distribution of earthquakes is influencing variation in the ...
-
(2004)The first part of the paper is directed to the investigation of the practical importance of possible longterm trends in the F2-layer for ionospheric prediction models. Using observations of about 50 different ionosonde ...
-
(1999)Geomagnetic paleointensity measurements from sedimentary records can be severely affected by viscous remanent magnetization (VRM). We present a method for determining varying amounts of long-term VRM acquired during the ...
-
(2006)The Eastern Southalpine Basement on the southern side of the Brixen granodiorite pluton is comprised of two rock volumes separated by a shear zone and characterised by contrasting thermo-mechanical evolutions. The first ...
-
(2001)I report here the experimental results on the dynamics of equilibration of silicate melts suspended from Ni loops of different diameters at 1400°C and at constant oxygen fugacity. It is found that saturation of silicate ...
-
(1999)Loparite-(Ce) is a ubiquitous accessory mineral in modally diverse albite-rich metasomatic rocks of the Burpala alkaline complex, Siberia. Compositionally, the mineral approaches the ideal formula NaREETi2O6 (REE = Ce > ...
-
(2001)Five test runs were performed to assess possible bias when performing the loss on ignition (LOI) method to estimate organic matter and carbonate content of lake sediments. An accurate and stable weight loss was achieved ...
-
(2005)The common observation that smaller particle-size fractions of sedimentary rocks yield younger K-Ar apparent ages than the larger particle-size fractions of the same stratigraphic age was analyzed with the aid of the ...
-
(2003)Love waves are one of the major contributors of noise in SH -wave reflection data. Suppressing them can be difficult, most importantly because their group velocity is almost equal to the shear wave velocity. By using the ...
-
(2004)Explicit expressions for the displacements generated in a non-gravitating, homogeneous, semi-infinite half-space by uniform surface pressure applied over a rectangular region are presented. These complement expressions for ...
-
(2006)The GPS velocity field of the present-day deformation in Iran is modeled using a 3-dimensional (3D) finite element approach. The deformation can be accommodated either by a continuum medium or by faults which are modeled ...
-
(2001)The paper intends to review the current status of low-flow hydrology - a discipline which deals with minimum flow in a river during the dry periods of the year. The discussion starts with the analysis of low-flow generating ...
-
(2000)Regional precursors of near earthquakes can possibly be identified in low-frequency seismic signals preceding a main shock. A special software package was used to examine seismic records of more than 200 earthquakes. More ...
-
(1998)During Devonian pulse of alkaline magmatism (370 Ma ago) 18 ultrabasic-alkaline-carbonatite comlexes were formed on the Kola Peninsula.
-
(1999)In the absence of an externally applied stress, the segregation of small amounts of granitic or tonalitic melts from their residual mafic crystals is possible only if the melt forms an interconnected network phase. ...
-
(2002)Analysis of teleseismic receiver functions at digital stations along the Bratsk–Irkutsk–Ulanbaatar–Undurshil profile suggests that low-velocity layers in the Earth's crust exist not only beneath the Baikal rift zone, where ...
-
(2001)Endowed with the theoretical knowledge of carbonate evaporation and the precipitation of CaMg carbonates from aqueous solutions the authors systematically researched the low temperature: formation of dolomite-like carbonates. ...
-
(1999)In vitro enrichment cultures of dissimilatory sulfate-reducing bacteria precipitated FeS and catalyzed its transformation into FeS2 at ambient temperature and pressure under anaerobic conditions. When compared to purely ...
-
(2000)The magnetic and magnetoresistance behavior of La Ca (Mn,Fe) O materials was investigated at low temperature. The result shows that with the increasing replacement of Mn by Fe, the ferromagnetic interaction of samples ...
