(1998)The loess/paleosol sequences of Central Asia are continuous terrestrial records of the Quaternary period and enable detailed comparison with paleoclimatic archives such as marine and ice core records in order to reconstruct ...
-
(1999)Loess rocks are widespread on the Earth. They occupy about 10% of global land area. Their thickness reaches up to 300 m in places and even more. Loess rocks differ in the different parts of the Earth. The 'warm' and the ...
-
(1988)According to the Second Law of Thermodynamics, 'natural processes tend from less probable to more probable states,' and we use the entropy of a system as a measure of the thermodynamic probability P of its state. For this ...
-
(2003)A paradox of volcanology is that the most fundamental part of its knowledge – the observation of volcanic processes and objects – is less strict and less well organized compared with experimental and theoretical approaches ...
-
(2003)Base-hydrolyzed sterols and long-chain alcohols of a marine eustigmatophyte, Nannochloropsis gaditana have been studied. Sterol composition of N. gaditana is similar to that of other member of this genus, with predominance ...
-
(1996)Data from literature have been verified and new estimates have been obtained for the total volumes of erupted material, average productivities, life spans, and other parameters of Kamchatkan volcanic centers that operated ...
-
(2004)A series of Cr-substituted goethites with (Cr:Fe molar ratio up to 0.12) were prepared. Thermal analysis of the solids indicates the formation of cation-deficient compounds that are more stable towards the transformation ...
-
(2001)Measurements performed by means of tiltmeters and extensometers in special-purpose underground observatories are an important part of the research on the crustal kinematic parameters in the northern Tien Shan. Long runs ...

-
(2001)Analysis of physical properties in long sediment cores (BDP96) from Academician Ridge in Lake Baikal indicates that major climato-limnological changes during the past 3.5 Myr occurred at about 2.5–2.8, 1.7–1.9, and 0.9–1.2 ...
-
(1999)Net flux of ferric iron from the subducted oceanic crust to the mantle has been estimated to constrain the evolution of the redox state of the Earth's mantle. The main mechanism responsible for the transfer of ferric iron ...
-
(2001)Combined results from time-series observations of currents and water properties from two moorings and a benthic tripod measuring near-bed velocity profiles are used to evaluate the potential for sediment transport 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 ...
-
(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 ...
-
(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 ...
