-
(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 ...
-
(PANGAEA, 2019-09-18)The Aktau succession is located at 44.03°N and 79.30°E in the Ili Basin, south-east Kazakhstan. The dataset contains measurement results from the Middle to early Late Miocene part of the succession (total height: 372 m, ...
-
(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 ...
-
(PANGAEA, 2016-12-13)During the Soviet Virgin Lands Campaign, approximately 23 million hectares (Mha) of Eurasian steppe grassland were converted into cropland in Northern Kazakhstan from 1954 to 1963. As a result Kazakhstan became an important ...
-
(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 ...
-
(PANGAEA, 2015-08-24)The present dataset includes results of analysis of 227 zooplankton samples taken in and off the Sevastopol Bay in the Black Sea in 1976, 1979-1980, 1989-1990, 1995-1996 and 2002-2003. Exact coordinates for stations 1, 4, ...
-
(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 ...
-
(PANGAEA, 2015-01-30)Relative to the past 2,000 years, the Arctic region has warmed significantly over the past few decades. However, the evolution of Arctic temperatures during the rest of the Holocene is less clear. Proxy reconstructions, ...
-
(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 ...
